Question

Write the algebraic phrase corresponding to the phrase: Five times the sum of twice a number and -5.

Answer 1

Let's let the variable x represent the unknown number.

First, the expression "sum of twice a number and -5" can be represented by: (2x + (-5))

Five times that sum would be: 5(2x +(-5))

Note: Recall that "twice" means 2 times a value.
