-6x + 4 = -4x + 6

Add 4x to both sides:

-2x + 4 = 6

Subtract 4 from both sides:

-2x = 2

Divide both sides by -2:

x = 2 / -2

x = -1

The answer is C.

HELP! Given a pyramid l = w = 9.0 mm and V = 324.0 cubic mm , find h in mm

harina [27]

Answer:

The answer to your question is height = 12 mm

Step-by-step explanation:

Data

l = w = 9 mm

V = 324 mm³

h = ?

Formula

V = $\frac{Ab x h}{3}$

Solve for h

3V = Ab h

3V / Ab = h or h = 3V / Ab

Find the area of the base

Ab = l x w

= 9 x 9

= 81 mm²

Substitution

h = $\frac{3(324)}{81}$

Simplification

h = $\frac{972}{81}$

Result

h = 12 mm

Solve Systems of Equations Algebraically. <br> y=x-8 <br> y=5x

larisa86 [58]

Answer:

(- 2, - 10 )

Step-by-step explanation:

Given the 2 equations

y = x - 8 → (1)

y = 5x → (2)

Substitute y = 5x into (1)

5x = x - 8 ( subtract x from both sides )

4x = - 8 ( divide both sides by 4 )

x = - 2

Substitute x = - 2 into either of the 2 equations for y

Substituting into (1)

y = - 2 - 8 = - 10

solution is (- 2, - 10 )
