x=2

Step-by-step explanation:

First, subtract 2 on both sides

7x+2=16

7x=14

Divide by 7 on both sides

x=2

Answer: x = 2

Step-by-step explanation: To solve for <em>x</em> in the equation you see here, our goal is to get <em>x</em> by itself.

Our first step will be to isolate the

term containing <em>x</em> which in this case is 7x.

To isolate 7x, we have to get rid of the +2 by subtracting 2 from both sides of the equation. On the left, +2 and -2 cancel out and we're simply left with 7x. On the right, 16 - 2 simplifies to 14.

So we have 7x = 14.

Now divide both sides by 7 and we find that <em>x = 2</em>.

Her senior year of college, Giselle decides to live off campus. In order to cover rent, she wants to get a job as a waitress.

SCORPION-xisa [38]

She would have to work at least 12 hours.

At Chili’s, she would be paid 11.75x + 33 per week, with x being the number of hours she worked.

At the Cheesecake Factory, Giselle would be paid 14.50x per week, with x being how many hours she worked.

We want to know how many hours Gisele would have to work for her pay at the Cheesecake Factory to be more than her pay at Chili’s

The inequality 11.75x + 33 < 14.50x is what has to be set up to solve the problem. At how many hours will the pay on the left be less than the pay on the right?

11.75x + 33 < 14.50x
33 < 2.75x
12 < x

So Giselle has to work greater 12 hours a week for her to make more money at the Cheesecake Factory.

MAXImum [283]

Answer:

Step-by-step explanation:

We are given fixed monthly charge = $70.

The cost of preschool per day = $45.

Number of days = d.

Total cost of d days = cost per day × number of days + fixed monthly charge.

Therefore, we get equation

880 = 45×d+70
