Answer:
88.5
Step-by-step explanation:
75 x .18
tip= 13.5
75 + 13.5 = 88.5
Factors of 40: 1,2,4,5,8,10,20,40
Factors of 60: 1,2,3,4,5,6,10,12,15,20,30,60
Greatest common factor of both is 20.
Answer:
- 3.9 hours
- 90 mph
Step-by-step explanation:
<h3>1.</h3>
The sum of the rates of painting, in fences per hour, is ...
1/9 + 1/7 = (9+7)/63 . . . . fences per hour
The total rate in hours per fence is the inverse of that:
63/16 = 3 15/16 ≈ 3.9 . . . hours to paint the fence
__
<h3>2.</h3>
The relevant relationship is ...
distance = speed × time
Let t represent Tom's speed in miles per hour. Then George's speed is (t-36). They both have traveled the same total distance at the point where Tom catches up.
(2+3)(t-36) = 3t
2t = 180 . . . . . . . add 180-3t
t = 90 . . . . . . divide by 2
Tom's average speed is 90 miles per hour.
If you would like to know the equality of the expression 4 * x/5 - 2 * x/5, you can calculate this using the following steps:
<span>4 * x/5 - 2 * x/5 = (4 - 2) * x/5 = 2 * x/5
</span>
The correct result is 2 * x/5, which is none of the results written above.
