Answer:
x=14
Step-by-step explanation:
If the y=8 then plug it in the equation:
3x-5(8)=2
It will be:
3x-40=2
3x=42
x=14
To answer this question we will use the following slope-point formula for the equation of a line:

Therefore, the equation of the line that has a slope of 1/3 and passes through the point (-3,3) is:

Simplifying the above equation we get:

Adding 3 to the above equation we get:

Answer:
It will take her about 7 days, because :
12*7=84
84+28= 112
112= +100
