The answer is C. I'm pretty sure of it.
Answer:
Nope. It would take 32 and 4/13 minutes, which is longer than 30 min.
Step-by-step explanation:
The distance is 35 miles and the speed 65 miles/hour
Dividie the distance by the speed to obtian the time required,
(35 miles)/(65 miles/hour) = 0.538 hours
No, 35 miles at the speed limit of 65 mph would require 0.538 hours, 0.038 hours more than 1/2 hour. 2 and 4/13 minutes more than 30 minutes.
Answer:
[(1/12)(5/5) + (1/20)(3/3)](x hours) = 1
(5/60 + 3/60)x = 1
(8/60)x = 1 we can reduce 8/60 by dividing out a 4
(2/15)x = 1 x both sides by 15/2
x = 15/2
x = 7 1/2 or 7.5 hours
Answer:
The system of equations is:
x + y = 15
xy = 15
Step-by-step explanation:
solve the first for y and substitute in the second:
y = 15-x
x(15-x) = 15
15x - x� = 15
15x - x� - 15 = 0
-x� + 15x - 15 = 0
x� - 15x + 15 = 0
