Answer:
28 miles
Step-by-step explanation:
Let w stand for the number of miles Derrick runs each week. Then after 4 weeks of training, he wants the total mileage to be 100 miles.
16 + 3w = 100
3w = 84 . . . . . . . subtract 16
w = 28 . . . . . . . . divide by 3
Derrick will run 28 miles each week to achieve his training goal.
Answer:
An ordinary annuity is a series of equal payments made at the end of consecutive periods over a fixed length of time. The opposite of an ordinary annuity is an annuity due, in which payments are made at the beginning of each period.
Step-by-step explanation:
3x - 10 + x = 90
4x = 100
x = 25 degrees
The answer is about 43. In other words, it was going 43 mph.
(2,716 feet) x (1mile / 5,280 feet) = <em>0.5144 mile</em> (rounded)
