3 1/3 minutes each since 3 1/3 times 3 is 10
Here are the steps for the equation:
3x+11=5x-9
subtract 3x
11=2x-9
add 9
20=2x
divide by 2
10=x
switch sides
x=10
Hope this helps! :)
-15 - X = -6; X = (-9); -15 + (-9) = -6
Answer:
16
Step-by-step explanation:
T = k/R where k is the constant of variation, T=time and R=speed.
Plug in the given values:-
12 = k/60
k = 12*60 = 720
So the equation of variation is T = 720/R
At 85 mph we have
T = 720 / 85 = 8.47 hours (answer)
