The trip was 6 hours long.
Step-by-step explanation:
Given,
The time to go to the island = 1
hours.
The return trip took 3/4 of the time of the original trip.
To find the time of the trip.
Let,
The time of the original trip is x hours.
The time for returning = ![\frac{3x}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3x%7D%7B4%7D)
According to the problem,
1
+
= x
or, x -
= ![\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D)
or,
= ![\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D)
or, x =
×4 = 6 hours
Hence,
The trip was 6 hours long.
Answer:
12
Step-by-step explanation:
get both x 's on the same side of the equation, 60= 9x-4x
then combine like terms so...
60=5x
do 60÷5=12
to get x alone so x=12
I think the answer is the second one b
Hope this helps
Gives an output of 1 I think
D. 8
you cross multiply. so 14x4=56
then divide 56 by 7 to get 8
