1) add 7 to both sides and get -5....so -5 >x
2) add 7 to both sides.....so get b<-5
3) add 17 to both side...so get z>1

Answer:
V≈50.27cm³
Step-by-step explanation:
Using the formulas
V=πr2h
3
l=r2+h2
Solving forV
V=1
3πr2l2﹣r2=1
3·π·42·52﹣42≈50.26548cm³
The values of the rates 4/5 mile in 8 minutes and 4 minutes to travel 2/5 mile are equal
<h3>How to compare and contrast the rates?</h3>
The rates are given as:
Rate 1 = 4/5 mile in 8 minutes
Rate 2 = 2/5 mile in 4 minutes
Calculate the above rates
This is done as follows:
Rate 1 = 1/10 mile per minute
Rate 2 =1/10 mile per minute
When the rates are calculated, the values are 1/10 mile per minute
Hence, the values of the rates 4/5 mile in 8 minutes and 4 minutes to travel 2/5 mile are equal

8x−7y=−5
Add 7y to both sides
8x−7y+7y=−5+7y
Simplify
8x=−5+7y
Divide both sides by 8
