Cost of tape: 4.95
no. of tape : x
budget : 37.85
4.95x < 37.85
+++
4.95x < 37.85
<u>÷4.95 ÷4.95</u>
x < 7.65
* you have to buy tapes that are less than 7.65
Assuming you bought 7 tapes.
4.95x < 37.85
4.95(7) < 37.85
34.65 < 37.85 *inequality is correct
If you buy more than 7 tapes, then, the cost of the tapes will be more than your budget. making the inequality incorrect.
We start with:
-10 = xy + z
When you want to solve for a certain variable, you generally follow pemdas in reverse, so subtract z from both sides first:
-10 - z = xy
And finally, divide both sides by y:
(-10 - z)/y = x
and there we go! sorry for the badly typed equations, I'm on my phone so there's only so much a can do :( hope I helped, and let me know if you have any questions!
-3x-13
since there is no x value the equation can not be solved any further.

Answer:
Sam had 80 dollars in his pocket. He was feeling generous, so he handed out equal amount of money to each of his friends. After he handed out the money, he had 53 dollars left. How much did Sam give out to each one of his friends?
Step-by-step explanation:
In this real-world problem, the money he had at the beginning resembles the 80 in the equation. The -3x is the money he gives out to each of his friends. The 53 on the right-hand side is the money he has left after he gives the money away.
