Question

Which of these is the algebraic expression for "seven more than the product of three and some number?"

A. 7 + 3 + x
B. 3 + 10 ÷ x
C. 3x + 7
D. 3 + 7x

Answer 1

That would be 3x + 7

Its the third choice

Answer 2

Hi there! The answer is C.

We can easily find our answer by letting the words "some number" be represented by x.

When we know this, we can search for the product of 3 and "some number", the product of 3 and x. We therefore have to multiply 3 and x and get 3x.

Finally we need to add 7 to get our final answer: Your answer is 3x + 7. The answer is C.
