Answer:
A. 7 years old
Step-by-step explanation:
6x-7=35 is the equation.
Add 7 to both sides, which gives you 6x=42.
Then both sides by 6, so 6/6=x and 42/6=7
So, x=7.
Since x is his daughter's age, x=7, so his daughter is 7.
Monday: t minutes
Tuesday: t + 15 minutes
Wednesday: t minutes
Thursday: t minutes
Friday: t minutes
Monday+Tuesday+Wednesday+Thursday+Friday= minutes ran
t+t+15+t+t+t=
5t+15 minutes
x + y = 50
x = 3y - 6
3y - 6 + y = 50
4y = 56
y = 14
