Answer:
<u>Problem A</u>
5 * 5 * x * x * x

<u>Problem B</u>
8 * 8 * 8

<u>Problem C</u>
4 * 4 * 4 * x * x * x * x

Answer:
-3/5
Step-by-step explanation:
First represent this with numbers. Less means subtraction -, times means multiplication *, is means equals =.
And let's represent "a number" with x.
63 - 15x = 72
Solve for x. First subtract 63 from both sides.
-15x = 72-63
-15x = 9
x = -9/15 = <u>-3/5</u>
Answer:
x=-5/7
Step-by-step explanation:
<span>12x+7 < -11:
Subtract 7 from each side.
12x+7 < -11
-7 -7
12x < -18
Divide each side by 12.
12x < -18
----- -----
12 12
x < -1.5 or x < -3/2
</span><span>5x-8 > 40:
Add 8 to each side.
5x-8 > 40
+8 +8
5x > 48
Divide each side by 5.
5x > 48
---- ----
5 5
x > 9.6
