Question

Problem 1:

Answer 1

Answer:

1) The variable is x

2) $1.5x > 51$ Solving the inequality we get x>34

3) $5b > 51$, solving the inequality we get b>10.2

Step-by-step explanation:

1. Define the variable:

The variable is x

2) Trini needs more than 51  cubic feet of soil to top up  his raised garden. Each bag  of soil contains 1.5 cubic  feet. Write and solve an  inequality to find how many  bags of soil Trini needs.

$1.5x > 51$

Solving the inequality

$x>\frac{51}{1.5}\\x>34$

Solving the inequality we get x>34

3) Write the inequality:

5 times b greater than 51

$5b > 51$

4) Solving the inequality

$5b > 51\\b>\frac{51}{5}\\b>10.2$

So, solving the inequality we get b>10.2
