b) the sum of 8 times x and 3 means ----> the number 8x plus the number 3

(8x+3)

c) the square of the sum of 8 times x and 3 means ----> the number 8x plus the number 3 multiplied by itself

(8x+3)(8x+3)=(8x+3)^2

What is a system of equations for the following situation? There is a total of 40 questions on a test. Some questions are multip
Elden [556K]

First we define the variables:

m = multiple choice questions

s = short answer questions

Next we need to satisfy 2 conditions:

1) There are a total of 40 questions. We can represent this mathematically using the variables I defined:

m+s=40

2) The multiple-choice questions are worth 2 points and the short-answer are worth 4 points but they need to total 100 points. This can also be represented mathematically:

2m+4s=100

By satisfying the conditions provided we were able to create the 2 equations!

m+s=40

2m+4s=100
