The answer is 8 .
Step-by-step explanation:
f(x)=36
36=3x+12
36-12 and 12 -12
36-12=24
24 divided by the 3 that left in the equation equals 8 .
36=3x+12
-12 -12
24=3x
divided 24 by 3 and get 8
Lets get all the information we need first.
A week has 7 days, you practice 30 min each day, so in a week you will practice a total time t of 30 min for 7 times, that is:

t = 210 min
So in a week you will practice a total of 210 minutes.
Rounded to 1 decimal place
