4x + 9y = 24
X + y = 10
Help ASAP

Answers

Answer 1

Answer:

14

Step-by-step explanation:

Answer 2

Answer:

(x, y) = (-16/5, 13[tex]\frac{1}{5}[/tex])

Step-by-step explanation:

4x + 9y = 24

x + y = 10 $\Rightarrow$ x = 10 - y

Substituting the value of x (second equation) into the first equation, we get:

4 * (10 - y) + 9y = 24

40 - 4y + 9y = 24

5y = -16

y = -16/5.

So, x = 10 - (-16/5) = 10 + 3[tex]\frac{1}{5}[/tex] = 13[tex]\frac{1}{5}[/tex]

Find the slope of the line that passes through the points (1,-4) and (3,-1).
A)5/4
B)2/3
C)-3/2
D)3/2

Answers

Answer:

The slope of the line = m = 3/2

Hence, option D is correct.

Step-by-step explanation:

Given the points

(1,-4)(3,-1)

Determining the slope between  (1,-4) and (3,-1)

(x₁, y₁) = (1,-4)

(x₂, y₂) =  (3,-1)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [-1 - (-4)] / [3 - 1]

               = [-1 + 4] / [2]

               = 3/2

Thus, the slope of the line = m = 3/2

Hence, option D is correct.

If x = 3 and y = 5, work out the value of a) 4x - 2y
b) 2x2 + 3y2

Answers

Answer:

A) 12-10

B)36+225

Step-by-step explanation:

A) 3x4=12, 5x2= 10= 12-10

B) 3x2=6x6=36, 3x5=15x15=225=36+225

For x = 3 and y = 5 the values of the given expressions are (a) 4x - 2y = 2 and (b) 2x² + 3y² = 93.

What is substitution?

Substitution is a mathemaical technique for replacing variables with specific or covnient values according to the context.

When the values of variables are given to solve an equation we just have to replace those numerical values in place of the given variables.

Given, x = 3 and y = 5.

∴ 4x - 2y is,

= 4(3) - 2(5).

= 12 - 10.

= 2.

And

2x² + 3y².

= 2(3²) + 3(5²).

= 2(9) + 3(25).

= 18 + 75.

= 93.

He'll end up paying 5,382 more than he borrowed.

Step-by-step explanation:

12 months in one year right so multiply 10 by 12.

You get 120 months in 10 years. Multiply $179.85 times 120 months.

Then you'll get the total amount he'll end up paying in those 10 years which is 21,582.

Subtract 21,582-16,200 and you get the amount of how much more money he'll end up paying which $5,382.

Michelle compares 5.8 x 106and 2.32 x 107. What steps could she use to compare the two numbers?

Answers

Answer:

5.8 × 10^(6) is greater.

Step-by-step explanation:

The 2 numbers she wants to compare are;

5.8 × 10^(6) and 2.32 x 10^(7)

Now,for her to compare easily both numbers will need to have the same powers of 10.

To this effect, let's convert the power of ten of the second number to the power of 6.

We will divide by 10 to get it.

Thus; 2.32 x 10^(7) ÷ 10 = 0.232 × 10^(6)

Comparing 0.232 × 10^(6) to 5.8 × 10^(6), we can see that they have same power of 10 but the greater number that precedes the power of 10 is 5.8.

Thus, 5.8 × 10^(6) is greater.

A tree in leilas backyard has been growing for 3 1/5 years. It is 3/4 meters tall how many meters per year?

Answers

Answer:

The tree grew 15/64 meters per year.                  

Step-by-step explanation:

Given

Length of a tree = 3/4 metersTotal time taken by the tree to grow 3/4 taller = 3 1/5 or 16/5 years

To determine

Per year growth of the tree in meters

Per year growth of the tree in meters can be determined by dividing the total length of a tree i.e. 3/4 meters by the total time taken by the tree to get 3/4 taller.

Per year growth of tree = Total Length  / Total time to grow

                                       = 3/4 ÷ 16/5

                                        = 3/4 × 5/16

                                        = [3×5] / [4×16]

                                        = 15/64 meters

Therefore, the tree grew 15/64 meters per year.

Answers

Answer:

The volume is 22.44 cubic inches

Step-by-step explanation:

The formula for the volume of a sphere is  

We know the diameter, but we can easily convert this into the radius by dividing it by 2, since the diameter is twice as long as the radius.

3.5/2 = 1.75

Now we can find the volume.

So, the average volume of a clementine is 22.46 cubic inches

The closest option you have is 22.44 so if you round it that should be your answer.

Answer:

Step-by-step explanation:

In rectangle, diagonals bisect each other and diagonals are equal.

So, AE = DE

∠ADE = ∠DAE            {Angles opposite to equal sides are equal}

6x - 1 = 2x + 15

6x      = 2x + 15 + 1

   6x = 2x + 16

6x -2x = 16

4x      = 16

       x = 16/4

       x = 4

∠ADE = 6x - 1

         = 6*4 - 1

         = 24 - 1

        = 23

1). What is the perimeter of the triangle?
с
5 mm
12 mm

Answers

Answer:

30

Explanation:

To begin, first find the length of the third side of the triangle. We are given that the two short sides of the triangle have lengths of 5 and 12. Use the Pythagorean Theorem to find the length of the third side:

a2+b2=c2,

where a and b represent the two shorter sides of the triangle, and c is the hypotenuse:

a2+b2=c2

52+122=c2

25+144=c2

169=c2

169−−−√=c2−−√

c=13

Now that we have the lengths of all three sides, add them together to find the perimeter:

5+12+13=30

The perimeter of the triangle is 30.
