Answer:
m = 57t, where the units of measurement of 57 are mph and that of t is hr.
Step-by-step explanation:
Use the given info to find the speed of the train, which is a unit rate:
95 miles 95 mi
------------------ = ------------- = 0.95 mile/min
1 hr 40 min 100 min
Better yet, use hours, not minutes.
95 miles 95 mi
------------------ = ------------- = 57 mph
1 hr 40 min 1 2/3 hr
Then m(t) = (rate)(time) = (57 mph)t This corresponds to Answer D.

Answer:
200 questions on the final exam.
Step-by-step explanation:
38% = 76 questions, 100% = 2.63157894737 x 76 = 200
(100/38=2.63157894737 hence this is the answer)
It is the exact opposite of an independent clause. It cannot stand alone as a sentence.
Answer:
Sarah bought 2 coach tickets and 3 first class tickets.
Step-by-step explanation:
Let c and f represent the numbers of coach and first class tickets purchased. Then c + f = 5, so that c = 5 - f.
The pricing equation is therefore
$380c + $1080f = $4000. Subbing 5 - f for c, we get the revised equation
380(5 - f) + 1080f = 4000.
After simplification, this becomes:
-380f + 1080f = 2100, or
700f = 2100.
Then f = 3 and c = 5 - f = 5 - 3 = 2.
Sarah bought 2 coach tickets and 3 first class tickets.
