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 m2+3 miles. 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.

"Samira ran 3 miles more that twice the number of miles Ada ran." This means that to get the number of miles that Samira ran, we will multiply the number of miles that Ada ran and then add 3 to the product.

Assume that Ada ran m miles, the following the steps mentioned above, we can calculate the number of miles that Samira ran as follows:
Samira ran: 2m + 3 miles

Comparing this to the choices, we will find that the correct choice is the second one:
 If Ada ran m miles, then Samira ran 2m + 3 ⁢ miles.

Here are the answers to the ones that i could see.
