Well, 217 miles ÷ 62 MPH is 3.5.
so it took the train 3.5 hours.
check it: 62 MPH x 3.5 hours, it went 217 miles
The perimeter of a triangle can be found by adding up all the sides
so the perimeter is :
5 + 8 + x =
13 + x <==

Start by dividing both sides by 3. Then take the square root of both sides. Then subtract 3 from both sides and divide by 2.
2 because the one side doubled and what happens to 1 side happens to them all, so 2
Answer:
Step-by-step explanation:
Just read it from left to right
13*155 = 2015
2015/26 = 77.5
You could also cancel the 13 and 26. If you do, you get
155/2 = 77.5
Either way works.
