Question

Translate this phrase into an algebraic expression 69 decreased by twice a number

Answer 1

Hey there!

First, let the unknown number mentioned be represented by the variable "x".

Now, since 69 is being decreased by a number identified as "twice" a number (x), you know that some number is being subtracted from 69. In addition, the number is twice an unknown value, x.

This would be represented by the algebraic expression:

69 - 2x

Hope this helps!
