Answer:
1:4
Step-by-step explanation:
there are 60 minutes in an hour
60/15=4
15:60=1:4
Perform indicated multiplications on left side.
8-40x=13 subtract 8 from both sides
-40x=5 divide both sides by -40
x=-5/40
x=-1/8
Note: There are no mixed numbers in this problem.
The base is 5 because 4×5 is 20
Most likely 5/9, I’m pretty sure
