How to solve algebraic equation?

An algebraic equation can be solved in a variety of ways.

The method you use to solve an equation depends on the type of equation and the information you are given.

Some of the most common methods to solve algebraic equations include using factoring, using the quadratic formula, completing the square, graphing, and using the substitution method.

This question uses the algebraic equation solving technique.

Step 1: Create an equation that relates the two numbers.

Let x = the smaller number

Let y = the larger number

2x + 3y = 86

Step 2: Substitute the given information into the equation.

We know that y = x + 7, so we can substitute that into the equation.

2x + 3(x + 7) = 86

Step 3: Solve the equation.

2x + 3x + 21 = 86

5x + 21 = 86

5x = 65

x = 13

Step 4: Substitute the value for x into the expression for y.

y = x + 7

y = 13 + 7

y = 20

Therefore, the two numbers are 7 and 14.

3. Ato Liku purchases a house for Br. 250, 000. He makes a 20% down payment, with a balance amortized by a 30 year mortgage at an annual interest rate of 12% compounded monthly. a) Determine the amount of the monthly mortgage payment. b) What is the total amount of interest Ato Liku will pay over the life of the mortgage? c) Determine the amount of the mortgage Ato Liku will have paid after 10 years?​

Answers

Answer:

a) To determine the monthly mortgage payment, we first need to calculate the amount of the loan, which is equal to the purchase price of the house minus the down payment. In this case, the loan amount is 250,000 * 0.8 = 200,000. Next, we need to calculate the monthly interest rate, which is equal to the annual interest rate divided by 12. In this case, the monthly interest rate is 0.12/12 = 0.01. Using the formula for the monthly mortgage payment (P = L[i(1+i)^n]/[(1+i)^n-1]), where P is the monthly payment, L is the loan amount, i is the monthly interest rate, and n is the number of payments (in this case, 30 years * 12 = 360), we can calculate the monthly payment as:

P = 200,000[0.01(1+0.01)^360]/[(1+0.01)^360-1] = 1326.91

b) To calculate the total amount of interest Ato Liku will pay over the life of the mortgage, we can subtract the original loan amount from the total amount of payments made over the life of the mortgage. In this case, that would be 360 * 1326.91 - 200,000 = 480,596.

c) To determine the amount of the mortgage Ato Liku will have paid after 10 years, we can multiply the monthly mortgage payment by the number of payments made in 10 years (10 years * 12 = 120). In this case, that would be 120 * 1326.91 = 159,223.20.

Here x = 5, The two angles are ∠B = 41° and ∠C=  63°.

What is a  pentagon?

A pentagon is a 2D polygon with five sides and five angles.

Pentagon is formed from three triangles, so the sum of angles in a pentagon = 3 × 180° = 540°.

We are given in the figure , following information about a pentagon:

3 angles are 90 degrees, one angle is (6x+1) degrees, and the other angle is (8x-11) degrees.

To solve for x, we need to add all of the angles together.

The sum of the angles in any polygon is always equal to (n-2)*180, where n is the number of sides in the polygon.

In this case, n=5, so the sum of the angles is (5-2)*180 = 540 degrees.

We can now solve for x by substituting our known values into the equation.

540 = 90 + (6x + 1) + (8x - 11)

540 = 14x

Estimate the number of kilograms of rice in 1 başin.
Estimate the number of grams of rice in 1 cup.
(b) A trader buys a sack of rice for 6 000 and sells it at 200 per basin.
Estimate the profit on a sack of rice.

(c) A trader charges #5 000 for a sack and 140 for a basin for beans.
Four women buy a sack of beans between them. They share the beans equally.
How many basins does each woman get?
How much does each woman save by buying the beans in this way?​

Answers

(a) 1 sack of rice contains 100 kg of rice. If 1 basin of rice is equal to 20 cups, then 1 sack is equal to 40*20 = 800 cups.

Therefore, 1 basin of rice contains 100/40 = 2.5 kg of rice.

1 cup of rice contains 2.5/20 = 0.125 kg of rice.

(b) A trader buys a sack of rice for 6 000 and sells it at 200 per basin. If 1 sack contains 800 cups of rice, then the total revenue from a sack of rice is 800*200 = 160,000.

Therefore, the profit on a sack of rice is 160,000-6,000 = 154,000

(c) A trader charges #5 000 for a sack of beans and 140 for a basin. If four women buy a sack of beans between them, they share the beans equally, so each woman gets 1/4 of a sack of beans, which is equal to 1/440 = 10 basins of beans.

Each woman gets 10 basins of beans which cost 14010 = 1,400. If they had bought the beans individually at 140 per basin, they would have spent 140*10 = 1,400.

On the following graph, use the purple line (diamond symbol) to plot this economy's long-run aggregate supply (RAS) curve. Then use the orange line segments (square symbol) to plot the economy's short-run aggregate supply (AS) curve at each of the following price levels: 90, 95, 100, 105, and 110

Answers

The purple line would be plotted at the level of output $60 billion, and the orange line segments would be plotted at 90, 95, 100, 105, and 110 respectively.

1. Plot the purple line at the level of output $60 billion.

2. Plot the orange line segments at 90, 95, 100, 105, and 110 respectively.

The long-run aggregate supply (RAS) curve is used to represent the natural level of output for an economy. In this case, the natural level of output is $60 billion of real GDP with a price level of 100. Therefore, the purple line should be plotted at the level of output $60 billion on the graph. The short-run aggregate supply (AS) curve is used to show how the level of output reacts to the price level. Therefore, the orange line segments should be plotted at 90, 95, 100, 105, and 110 respectively. This will show how the level of output changes when the price level is different from the natural level. This will help to illustrate how the economy may react when the price level is different than expected.

Tan x = 1/ cot x or sin x / cos x

Cot x = cos x / sin x

We have,

Right triangle ABC.

∠C = 90

The other two sides are a = 8 and b = 8

This means,

The angle opposite to the side a = 8 and b = 8 are equal.

Now,

∠A = ∠C

∠C + ∠A + ∠B = 180

90 + ∠A + ∠B = 180

2∠A = 180 - 90

∠A = 90/2

∠A = 45

∠B = 45

Now,

c² = a² + b²

c² = 64 + 64

c² = 128

c = √128

c = 11.31

Thus,

Sin A = a/c = 8/11.31 = 0.71

Cos A = b/c = 8/11.31 = 0.71

1. Fractions equal to 1/2

Answers

Answer: Answers vary…

Step-by-step explanation:

Equivalent fractions can be written by multiplying or dividing both the numerator and the denominator by the same number. Some fractions equivalent to 1/2 are: 2/4, 3/6, 4/8, 5/10, 6/12, etc. This is because equivalent fractions have the same value in reduced form.

A group of researchers establish a p-value of 0.05 for their hypothesis test. What does this mean?


a. The probability of getting a significant result for the test is 5%.

b. There is 5% probability that a true null hypothesis will be rejected.

C. The chi-square critical value for their dataset is 0.05

d. Only measured values of 0.05 or greater will be included in the test.

Answers

Answer:

b

Step-by-step explanation:

b. There is 5% probability that a true null hypothesis will be rejected.

A p-value of 0.05 represents the probability of obtaining a test statistic as extreme or more extreme than the one observed under the assumption that the null hypothesis is true. In other words, it is the probability of observing the data or more extreme data assuming the null hypothesis is true. It is also the threshold level of significance beyond which the null hypothesis is rejected in favor of the alternative hypothesis. A p-value of 0.05 means that there is a 5% probability that the observed results occurred by chance under the null hypothesis and that there is a 95% probability that the observed results occurred due to a real effect.

A bottle of liquid laundry detergent priced at $16.99 for a 52-load bottle has been changed to $16.49 for a 48-load bottle. By what percentage has the price per load changed?

Answers

Answer:

  5.1% increase

Step-by-step explanation:

You want the percentage change in price per load when the price of detergent went from $16.99 for 52 loads to $16.49 for 48 loads.

Percentage change

The percentage change is given by the formula ...

  ((new price)/(old price) -1) × 100%

Price per load

The price per load is found by dividing the price of the bottle of detergent by the number of loads it will wash.

  old price per load = $16.99/52 ≈ $0.32673

  new price per load = $16.49/48 ≈ $0.34354

Application

Then the percentage change is ...

  (0.34354/0.32673 -1) × 100% ≈ 0.05145 × 100% ≈ 5.1%

The price per load has increased by about 5.1%.

which choice is equivalent to the product below? √6/8 x √6/18

Answers

Answer: √6/8 x √6/18

Step-by-step explanation: The square root of A over B is the same as the squared of A, so it's important to know that before I start with this product. To go over the square.

I can do that if I combine the two square roots under the exact square root. This is only for multiplication.

I could take the square root of the term separately

Since I'm using fractions, I'll add the tops and bottoms to the equation.

The square root is eight times 18 and the squared root is six times six. It is the square to 36 over. It's eight times 18. There are 44 items.

The square to 36 is a question. I don't know what time it gives me. There were 36. 36 times six is 6. Six Over would be this. What time gives me 1 44?

Twelve times. 6/12 would be the day. It doesn't want me to reduce that, but I could.

The answer would be 6/12.
