Question

Translate this phrase into an algebraic expression.

7 more than twice Jose's height
Use the variable ; to represent Jose's height.

Answer 1

2x+7

Explanation:

Let's mark Jose's height with x. Of course, you can use any other letter or symbol.

We now need to express another value through this x. That other value we can mark with y.

This y is said to be 7 more then twice Jose's height. Jose's height is x, as we've already said, so:

y = 7 + 2•x (seven more than twice x)

That means that y = 2x+7.
