The equation 3x - y = - 1; - 3x - y = 5 when solved using the elimination method is x = -1 and y = -2 respectively.

3x - y = - 1

- 3x - y = 5

Subtract the equation to eliminate y

3x - (-3x) = - 1 - 5

3x + 3x = - 6

6x = - 6

divide both sides by 6

x = -6 / 6

x = -1

Substitute x = -1 into

3x - y = - 1

3(-1) - y = -1

-3 - y = - 1

- y = - 1 + 3

-y = 2

y = -2

Therefore, the solution to the simultaneous equation is (x, y) = (-1, -2)

The total interest paid for the period of three months will be $600 on the loan amount of $550000.

The interest is the charges levied on the amount which we borrow from any bank for a particular period of time.

Here in the question given data is

P= $550000

R=2.0%+2.8%=4.8%

T=1/4 years or three months

So from the simple interest formula

SI = PRT / 100

= 550000 x 4.8 x 1/4 / 100

= 6600

Hence, the total interest paid for the period of three months will be $600 on the loan amount of $550000.

The number of new jobs that would be created would be 1,120,000. This is calculated by multiplying the number of workers (16,000,000) by the projected job growth rate (7%) which equals 1,120,000.

The average of the numbers 11, 20, 13, and 16 is 15

The average may be calculated by dividing the total number of values by the sum of all the numbers. An average of the values in a sample of data may be used to determine a mean. In other words, the arithmetic mean is another name for an average. A mean is a term used to describe the average.

Finding an average helps us understand a general pattern of behavior or trend.

The equivalent equation to Paolo's equation is,

w = Start Fraction uppercase P minus 2l Over 2 End Fraction.

What is algebraic operation?

A basic algebraic operation in mathematics is any of the common arithmetic operations, such as addition, subtraction, multiplication, division, raising to a whole number power, and taking roots (fractional power).

Multiplication and division tasks should be completed first from left to right, followed by addition and subtraction tasks from left to right.

Given:

uppercase P = 2 (l + w)

Simplifying this,

uppercase P = 2l + 2w

Subtract 2l from both sides,

uppercase P - 2l = 2l  + 2w - 2l

uppercase P - 2l = 2w

Divide both sides by 2,

(uppercase P - 2l) / 2 = 2w / 2

Let x be the number of guppies Percious can purchase.

We know that the total cost of the goldfish, starfish and guppies is less than or equal to $80.

We can use this information to write an inequality:

This inequality represents the total cost of the goldfish, starfish, and guppies.

By solving this inequality we can find the number of guppies Percious can purchase.

To solve this inequality, we can first simplify it by combining like terms:

44 + 6x <= 80

Then we can subtract 44 from both sides:

6x <= 36

And finally, we divide both sides by 6:

x <= 6

So, Percious can purchase a maximum of 6 guppies if she wants to spend all of her money.

Step-by-step explanation:

One of the rules of ratio includes sorting ratio in order according to the question. In this case, squash is mentioned first, then water. Hence, the ratio is:

squash:water = 1:6

Use cross multiplication:

1       :       6

100  :        ?

Multiply 100 by 6 then divide it by 1: which basically means 100 * 6 = 600 ml.

If you are unfamiliar with cross multiplication, then simply find out how many times did you have to multiply the 1 in the squash ratio to result to 100, which is 100, then multiply 6 by that answer = 6 * 100.

The equation that represents circles that have a diameter of 12 units and a center that lies on the y-axis is x²+ (y-3)² = 36. Therefore, option A is the correct answer.

The equation of circle provides an algebraic way to describe a circle, given the center and the length of the radius of a circle. The equation of a circle is different from the formulas that are used to calculate the area or the circumference of a circle.

The standard equation of a circle with center at (x₁, y₁) and radius r is (x-x₁)²+(y-y₁)²=r²

The standard form for finding the equation of a circle is expressed as;

(x-a)²+ (y-b)² =r²

Where; (a, b) is the center of the circle and r is the radius of the circle

Given that, diameter = 12 units

So, radius = 12/2 = 6 units

If the center lies on the y-axis, the center will be at (0, 3)

Substituting into the formula, we will have (x-0)² + (y-3)² = 6² equivalent to x²+ (y-3)² = 36

Therefore, option A is the correct answer.

The tangent of the subtraction of angles x and y is defined as follows:

tan(x - y) = (36 - 20π)/(48 + 15π)

The tangent of the subtraction of two angles is obtained according to the identity presented as follows:

tan(x - y) = [tan(x) - tan(y)]/[1 + tan(x)tan(y)]

The tangent of angle x is given as follows:

3/4.

The tangent and cotangent are defined as follows:

Hence the tangent of angle y is obtained inverting the numerator and the denominator of the function, as follows:

tan(y) = 5π/12.

The subtraction of the two tangents is given as follows:

tan(x) - tan(y) = 3/4 - 5π/12 = 9/12 - 5π/12 = (9 - 5π)/12.

The quotient of the two tangents is given as follows:

tan(x)tan(y) = 3/4 x 5π/12 = 15π/48.

Then the denominator of the expression is given as follows:

The equation that can be used to determine the total cost, given the number of movie tickets, is c = 8. 50 c

The equation that shows the total cost when you buy a certain number of tickets, can only be found after you solve for the ticket price.

The ticket price is :
= Cost of tickets / Number of tickets

= 42. 50 / 8

= $ 8. 50

The equation for the total cost would therefore be:

Answer: Elijah's debt-to-credit ratio is 37%.

Step-by-step explanation:

Elijah's debt-to-credit ratio is the ratio of the amount of money he owes to the total amount of credit he has available.

To calculate the debt-to-credit ratio, we need to divide the amount of debt by the total amount of credit, and then multiply by 100 to get the answer in percentage.

Debt = $2,127.50

Credit = $5,750.00

Debt-to-credit ratio = (Debt / Credit) * 100

Debt-to-credit ratio = (2127.50 / 5750) * 100 = 37.29 ~ 37%

So the answer is: b) 37%

We can use the tangent function to solve for the height of the tower. The tangent of an angle is the ratio of the opposite side to the adjacent side in a right triangle.

First, we'll find the opposite side (the height of the tower) using the angle of elevation:

tan(21°) = opposite / 300

opposite = 300 * tan(21°)

Then we'll find the opposite side (the depth of the base of the tower below the window) using the angle of depression:

tan(20°) = opposite / 300

opposite = 300 * tan(20°)

Now we can add the two opposite sides we found to get the total height of the tower

height = opposite(elevation) + opposite(depression)

height = 300 * tan(21°) + 300 * tan(20°)

The angle should be converted to radians before using the tangent function, and the final answer should be rounded to 2 decimal places.

Step-by-step explanation:

Since Z and 92 both have vertical angles, they are equal. Subtract from 180 to determine the measure of the other angle, which is 88 degrees since it forms a straight line with the 92-degree angle. Solve the expression by setting the value at 88.

∠AOB + ∠BOC = 180°

92°+( 10x  +  32 )° = 180°

10x + 32° = 180 - 92

10x + 32° = 88

10x = 88 - 32

10x = 56

x = 56 ÷ 10

x = 5.6°
