12. Roger got on a train and
traveled 3.6 miles. Then he switches
to a different train and traveled 7.3
miles more. How far did Roger travel
in all?

Ok but uh what do you need with?

step-by-step explanation:

yes it is1. move over 2 points on the x-axis2. move over 2 points on the y-axis

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

The variables should add up to equal 1
