Question

bretts fish tank can hold up to 10.5 gallons of water before it overflows. brett has poured 9 gallons of water into his fish tank so far. let x represent how many more gallons of water brett can pour into his fish tank. which inequality describes the problem? 9 + x ≤ 10.5 9 + x ≥ 10.5 solve the inequality. then, complete the sentence to describe the solution. brett can pour at most \boxed{} more gallons of water into his fish tank.

Explanation:

Step1: Select correct inequality

The total water (9 + x) cannot exceed 10.5, so $9 + x \leq 10.5$

Step2: Isolate x via subtraction

Subtract 9 from both sides:
$9 + x - 9 \leq 10.5 - 9$

Step3: Simplify to find x

Calculate the result:
$x \leq 1.5$

Answer:

Correct inequality: $9 + x \leq 10.5$
Brett can pour at most 1.5 more gallons of water into his fish tank.
