Answer:
21
Step-by-step explanation:
Of means multiply and since we want an estimate we can round 72 to 70
30% * 70
.30 * 70
21
Subtract 40 from both sides
-vp+40-40<95-40
Simplify
-vp<55
Multiply both sides by -1 (reverse the inequality)
(-vp) (-1) > 55 (-1)
Simplify
vp> -55
Divide both sides by v
vp ÷ v > -55 <span>÷ v
</span>
Simplify
p> -55 <span>÷ v </span>
When you multiply or divide two positives or two negatives, the answer is positive.
72/9 = 8
-72/(-9) = 8
Correct answer: Choice D.
First you would divide by 2 in both sides
P/2 = l + w
Then you would subtract w from both sides
P/2 - w = l
This is the easiest method do isolate l
You can also distribute the 2 to ( l + w) first
P= 2l + 2w
Then subtract 2w from both sides
P - 2w = 2l
Then you would divide by 2
(P - 2w) / 2 = l
P/2 - w = l
