Question

Bily is helping to make piZzas for a school function. He's made 25 pizzas so far His principal asked him to make at least 30 pizzas but no more than 75 Solve the compound inequality and interpret the solution 30 S x+25 75

Answer 1

5 ≤ x ≤ 50

Explanation:

To solve an inequality with terms on both sides, you have to isolate the variable in the center by cancelling out the terms on both sides. So in this case you would not only subtract 25 from 30 (on the left) and the 25 in the center, but you would also have to subtract from the 75 (on the right)

30 ≤ x + 25 ≤ 75

-25 -25 -25

5 ≤ x ≤ 50

Answer 2

The answer is Option B

We know that this inequality doesn't require any negative number division, there's no need to switch the ≤'s into ≥'s.

So now, all we have to do is subtract 25 from every number, giving us 5≤x≤50
