Step-by-step explanation:
Hope the picture helps!
Let's solve your inequality step-by-step. <span><span><span>−<span>3<span>(<span><span>−2</span>−x</span>)</span></span></span>+x</span>>20</span>
<span />Step 1: Simplify both sides of the inequality. <span><span><span>4x</span>+6</span>>20</span>
<span />Step 2: Subtract 6 from both sides. <span><span><span><span>4x</span>+6</span>−6</span>><span>20−6</span></span><span><span>4x</span>>14</span>
<span />Step 3: Divide both sides by 4.<span><span><span><span><span>4x</span>4</span></span></span>><span><span><span>144</span></span></span></span>
<span><span><span><span /></span></span></span><span>x><span><span>7/2</span></span></span>
Answer:
The score on the next test must be between 86 and 98, inclusive
Step-by-step explanation:
Write an inequality using the average:
86 ≤ 
≤ 90
Solve for x:
multiply everything by 3:
258 ≤ x + 83 + 89 ≤ 270
258 ≤ x + 172 ≤ 270
subtract 172 from everything:
86 ≤ x ≤ 98
The score on the next test must be between 86 and 98, inclusive
