Answer:
A
Step-by-step explanation:
2X^2+22x+318=1270
2x^2+22x-952=0
x^2+11x-476=0
(x+28)(x-17)=0
x=17
There will be 4 water stations.
Why?
3/4 = .75 as a decimal
Personally, I believe that it’s easier to use decimals, I can explain the way in fractions in the comments if you’d like, just ask.
Anyway, .75 • 4= 3
or 3 / .75 = 4 (division is easier with bigger numbers)
so, there will be 4 water stations, given that the one race is 3 miles long.
If this explanation seems unclear, I’d be happy to explain. Feel free to ask in the comments!! I’m happy to help.
Hope this helps!

Answer:
6 laps
Step-by-step explanation:
Each lap Jeffrey needs to run is one tenth of a mile he wants to run threee fifths of a mile how many laps does he need to run
One tenth of a mile = 1/0
Three fifths of a mile = 3/5
From the question:
1/10 mile = 1 lap
3/5 mile = x
Cross Multiply
1/10 mile × x = 3/5 mile × 1 lap
x = 3/5 mile × 1 lap/ 1/10 mile
x = 3/5 ÷ 1/10
x = 3/5 × 10/1
x = 6 laps
Therefore, for there fifths of a mile(3/5) he needs to run 6 laps
