Question

Explain step by step please!

Answer 1

Answer:

2.5lb

Explanation:

In equation form the question is asking for x in

$30(x) = 75$

Since multiplication is reversible (to be division), we can switch the equation up.

$75$ ÷ $30 = x$

So the answer is

$75$ ÷ $30 = 2.5$

Answer 2

Answer:

Each book weighs 2.5 pounds.

Step-by-step explanation:

75/2.5 is 30.  Or you could also get the answer by 30* 2.5 which it would be 75. So, therefor, the answer is 2.5.
