Question

samira ran 3 more miles than twice the number of miles ada ran. which statement makes this comparison using the correct variable expression? if ada ran m miles, then samira ran 2m + 3 miles. if ada ran m miles, then samira ran 2(3)+m miles. if ada ran m miles, then samira ran 3m + 2 miles. if ada ran m miles, then samira ran $\frac{m}{2}+3$ miles.

Explanation:

Step1: Translate the description into math

Let the number of miles Ada ran be $m$. Twice the number of miles Ada ran is $2m$. Samira ran 3 more miles than that, so we add 3 to $2m$.

Step2: Form the expression

The expression for the number of miles Samira ran is $2m + 3$.

Answer:

If Ada ran $m$ miles, then Samira ran $2m + 3$ miles.
