OlgaM077 [116]

The solution to the inequality expression is x ≥ 30

<h3>How to solve the inequality expression?</h3>

The inequality expression is given as:

8x - 3(2x - 4) ≤ 3(x - 6)

Open the brackets in the above inequality expression

8x - 6x + 12 ≤ 3x - 18

Collect the like terms in the above inequality expression

8x - 6x - 3x  ≤ -12 - 18

Evaluate the like terms in the above inequality expression

-x  ≤ -30

Divide both sides of the above inequality expression by -1

x ≥ 30

Hence, the solution to the inequality expression is x ≥ 30

Marta is solving the equation S = 2Πrh + 2Πr2 for h. What is the result?
yulyashka [42]
<span>S = 2Πrh + 2Πr2
Manipulating the equation for h.
Step 1. subtract </span><span>2Πr2 on both sides.

</span>S - 2Πr2 = 2Πrh + 2Πr2 - 2Πr2
S - 2Πr2 = <span>2Πrh
</span>
Step 2 . divide <span>2Πr on both sides
</span>
(S - 2Πr2)/2Πr = 2Πrh/<span>2Πr

</span><span>h = </span>(S - 2Πr2)/2Πr
