Question

concrete building blocks weigh 28 pounds each. Using b for the number of concrete blocks and w for the weight, write two equations that relate to the two variables. one equation should begin with w = and the other should begin with b=.

Answer 1

Answer:

The two equations are: $w=28b$ and $b=1/28w$

Step-by-step explanation:

Concrete building blocks weigh 28 pounds each.

Let b be the number of concrete blocks and w be the weight of blocks.

So, the two equations that relate to the two variables are:

$w=28b$ and $b=1/28w$

Answer 2

Concrete building blocks weigh 28 pounds each. 1b=28
28(5) = w
w= 140 pounds

56/28=b
b = 2 blocks
