Answer:

x = 8

z = 86

Step-by-step explanation:

6x + 46 = 13x - 10 (Because they're vertical angles)

6x - 13x = -10 - 46

-7x = -56

x = 8

6x + 46

6(8) + 46

z + 94 = 180

z = 86

1. In the formula V = lwh, the variable h needs

ANTONII [103]

Answer:

$H=\frac{V}{LW}$

see the explanation

Step-by-step explanation:

we know that

Using inverse operations, the formula can be rearranged to solve for any one of the variables that might be unknown.

we have

$V=LWH$

The operation of multiplication is used in the formula

The inverse operation of division should be used to isolate the variable H

Divide both sides by LW

$\frac{V}{LW}=\frac{LWH}{LW}$

simplify

$H=\frac{V}{LW}$

5x+8=9x+12 helpppppp

Marina CMI [18]

Hi there! :)

Answer:

$\boxed{X=-1}$

*THE ANSWER MUST HAVE A NEGATIVE SIGN!*

Step-by-step explanation:

First, you subtract by 8 from both sides of an equation.

5x+8-8=9x+12-8

Subtract.

12-8=4

5x=9x+4

Then, you subtract by 9x from both sides of an equation.

5x-9x=9x+4-9x

Simplify by equation.

-4x=-4

Divide by -4 from both sides of an equation.

-4x/-4=-4/-4

Divide by the numbers from left/right.

-4/-4=-1

$\boxed{X=-1}$ , is the FINAL/CORRECT ANSWER! :)

Have a nice day! :)

:D
