Answer:

x=\frac{23}{6} or 4.6

Step-by-step explanation:

3x + 2x + 7 = 10x - 16

5x+7=10x-16

Subtract 7 from both sides:

5x+7-7=10x-16-7\\5x=10x-23

Subtract 10x from both sides:

5x-10x=10x-23-10x\\-5x=-23

Divide both sides by -5:

\frac{-5x}{-5}=\frac{-23}{-5}\\x=\frac{23}{5} or 4.6

Daniel is working two summer jobs, making $8 per hour babysitting and making $15 per hour lifeguarding. In a given week, he can
natima [27]
If he makes $8 per hour while babysitting, then if he works 3 hours - then he’d get $24 for babysitting.

He still has to make $176.
He can work 18 hours, if he uses up 3 hours babysitting, he has 15 hours left.

15 hours times $15 = 225 (too much)
12 hours times $15 = $180 ( he saves three hours)

He has to do 12 hours of life guarding to meet his goal - he will have three spare hours.

Sorry if I’m wrong, I think I’m right tho
