Answer:Michael spent 53 1/4 hours
training.
Step-by-step explanation:
Over the course of four weeks Mia spent 35 1 2 hours training for a race. This can be written in decimal point as 35.5 hours.
Michael spent 1 1 2 times that amount training for the same race. Converting 1 1 2 to decimal, it becomes 1.5 hours.
This means that the number of hours that Michael spent training will be 35.5 × 1.5 = 53.25 hour.
Converting 53.25 hours to mixed fraction, it becomes
53 1/4 hours
27/36 is 0.75 as a decimal!
Answer:
There are no solutions.
Step-by-step explanation:
Let's solve your equation step-by-step.
9m−4=−3m+5+12m
Step 1: Simplify both sides of the equation.
9m−4=−3m+5+12m
9m+−4=−3m+5+12m
9m−4=(−3m+12m)+(5)(Combine Like Terms)
9m−4=9m+5
9m−4=9m+5
Step 2: Subtract 9m from both sides.
9m−4−9m=9m+5−9m
−4=5
Step 3: Add 4 to both sides.
−4+4=5+4
0=9
