Answer:
<h2>1 < x < 6 ⇒ x ∈ (1, 6)</h2>
Step-by-step explanation:
3x - 8 > -5 <em>add 8 to both sides</em>
3x > 3 <em>divide both sides by 3</em>
x > 1
2x - 7 < 5 <em>add 7 to both sides</em>
2x < 12 <em>divide both sides by 2</em>
x < 6
From x > 1 and x < 6 we have the solution 1 < x < 6 ⇒ x ∈ (1, 6)
Answer:
4 in
Step-by-step explanation:
volume = 64 in³
side = cubic root of 64 in³
side = 4 in
Check: If a cube has side 4 in, then its volume is 4 in × 4 in × 4 in = 64 in³.
This shows that the answer 4 in is correct.
