Question

Translate the sentence into an equation.

The sum of 8 times a number and 9 is 5.
Use the variable b for the unknown number.

Answer 1

8b + 9 = 5

Explanation:

The SUM of 8 times a number...

"The sum" means that we are adding and "times" means that we are multiplying. We can substitute a variable (b) for "a number:"

8b

And 9 is 5.

"And 9" suggests that we are adding 8b to 9 and "is" suggests that we have to also input an equal to sign.

8b + 9 = 5

Thus, the equation for this sentence is:

8b + 9 = 5
