I don't really have an explanation, I'm just good at quick math,
I'm sorry if you wanted an explanation, I would explain but I am really bad at explaining math.
Answer:
2 miles
Step-by-step explanation:
We can use ratios to solve this problem
3/4 miles x miles
--------------- = ---------------
3/8 hours 1 hours
Using cross products
3/4 * 1 = 3/8 * x
Multiply by 8/3 to isolate x
3/4 * 8/3 = 3/8*8/3 *x
8/4 = x
2 =x
Answer:
㏒₃7=2x-5
Step-by-step explanation:
80% because I did the math
Answer: 8 7/10 hours
whole part = 8
fractional part = 7/10
========================================================
Work Shown:
x = number of hours driving
(5/6)x = total number of gallons of gas used
(5/6)x = 7 & 1/4
(5/6)x = 7 + 1/4
(5/6)x = 28/4 + 1/4
(5/6)x = 29/4
x = (29/4)*(6/5)
x = (29*6)/(4*5)
x = 174/20
x = 87/10
x = (80+7)/10
x = 80/10 + 7/10
x = 8 + 7/10
x = 8 & 7/10
This is the same as writing 8 7/10
Amy drove 8 full hours, plus an additional 7/10 of an hour.
That mixed number converts to the decimal value 8.7
