2(3z-2)+8=34
6z - 4 + 8 = 34
6z + 4 = 34
6z = 34 -4
6z = 30
z =30/6
z = 5

answer D. z=5

Step 1: 2(3z-2)+8=34
Step 2: 6z - 4 + 8 = 34
Step 3: 6z + 4 = 34
Step 4: 6z = 34 -4
Step 5: 6z = 30
Step 6: z =30/6
Step 7: z = 5

Hey everyone. I need the answer to this ASAP!: Michael knows that 2 cans of paint is the exact amount he needs to paint a 10-foo

Ivahew [28]

Answer:

See attachment for graph

Step-by-step explanation:

Given

$2 cans = 10ft\ by\ 12ft$

Required

Graph the relationship between both parameters

First, calculate the area;

$Area = 10ft * 12ft$

$Area = 120ft^2$

This implies that: (2, 120) i.e. 2 cans for 120ft^2.

So we have:

(0,0) and (2,120)

(0,0) implies that: 0 cans for 0 square feet

Calculate the slope:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{120 - 0}{2-0}$

$m = \frac{120 }{2}$

$m = 60$

The equation is:

$y = m(x - x_1) + y_1$

So, we have:

$y = 60 * (x - 0) + 0$

$y = 60 * (x )$

$y = 60 x$
