Question

What is the algebraic expression for five times the sum of seven and a number?

Answer 1

To find the algebraic expression:

Let $x$ be the number.

Add $7$ with number $x$:

$7+x$

Now, Multiply $5$with $7+x$:

$5·\left(7+x\right)$

Hence, the algebraic expression is $\mathbf{5}\left(7+x\right)$.
