<h3>What is a system of inequalities?</h3>
A system of equations is when two or more variables are related, and inequalities are built to find the values of each variable.
The variables are given as follows:
- Variable x: Number of color copies.
- Variable y: Number of gray scale copies.
She needs to print no fewer than 8 copies, hence:
.
It takes 4 minutes to print a color copy and 2 minutes to print a grayscale copy. She has at most 25 minutes, hence:
.

Answer:
4(3x+12)=4x+22
Step-by-step explanation:
Okay. It would be written like this: n/7 - 2 = 10. Add 2 to both sides and then you get n/7 = 12. Multiply by 7 to isolate the “n”. Then, you should get n = 84. Plug it in. 84/7 is 12. 12- 2 = 10. There. n = 84.
You mean 23 is what percent of 16 right?
Well let's divide and multiply by 100.
23 / 16 = 1.4375 ≈ 1.440
1.440 * 100 = 144.0
Therefore 23 is approximately 144% (exact. 143.75%) of 16.
You can confirm by answer by multiplying 16 by 1.4375.
