Answer:

7x - 32

Step-by-step explanation:

1. Distribute meaning multiply -8 by 4 then by -3x; this results in -32+24x.

2. Afterward, you rewrite your expression: -32+24x-17x.

3. Subtract like terms and rewrite for final answer: 7x-32

1. distribute the -8 into the parentheses and you get -32+24x-17x
2. combine like terms and get -32+7x
3. if you need to make it simpler set the equation = to zero -32+7x=0 and then add the 32 on both sides
4. 7x=32 and then divide by 7 and you get 32/7 or approximately 4.571

I hope this helped!! :)

Answer:

the third side is 4.

Step-by-step explanation:

Using Pythagorean theorem of a^2 + b^2 = c^2 for right triangles, substitute

the numbers to show ( $\sqrt{65})^{2}$ + $b^{2}$ = $9^{2}$ and solve for b. The square root and square cancel each other out, so you get 65 + $b^{2}$ = 81.

Subtract 65 from both sides to get $b^{2}$ = 16.

Then take the square root of both sides to get b = $\sqrt{16}$ which equals 4.

Scott bought a pen and received change of $4.75 in 25 coins, all dimes and quarters. How many of each kind did he receive?

dangina [55]

Answer:

He received 10 dimes and 15 quarters.

Step-by-step explanation:

Dimes = $0.10

Quarters = $0.25

Variable x = dimes

Variable y = quarters

Create a pair of linear equations:

0.10x + 0.25y = 4.75

x + y = 25

Isolate any variable, using an equation of your choice:

x + y = 25

x = 25 - y

Plug in this new value of x into the other equation:

0.10(25 - y) + 0.25y = 4.75

Use the distributive property:

2.5 - 0.10y + 0.25y = 4.75

Combine like terms:

2.5 + 0.15y = 4.75

Isolate variable y:

0.15y = 2.25

y = 15

Plug in the value of y into any equation:

x + y = 25

x + 15 = 25

Isolate variable x:

x = 10
