Answer:
t < 1.5
Step-by-step explanation:
Mon-Thu: 5.5 hours
each of the remaining 3 days: t hours each day
total time: 3t + 5.5
The total time must be less than 10 hours.
3t + 5.5 < 10
3t < 4.5
t < 1.5
solve for x.
x+9y=18
Add -9y to both sides.
x+9y+−9y=18+−9y
x=−9y+18
solve for y.
x+9y=18
Add -x to both sides.
x+9y+−x=18+−x
9y=−x+18
Divide both sides by 9.
9y/9=−x+18/9
y=−1/9x+2
2(3x5) + 2(3x9) + 2(5x9) = 174 in2
I believe this is correct answer
