Triangle JKL has a base that is 1 unit long
Triangle J'K'L' has a base that is 3 units long
3 units / 1 unit = 3
The scale factor is 3.
6.4 - 2x - 6.63x = 610.5
subtract 6.4 from both sides
-2x -6.63x =604.1
collect like terms
-8.63x = 604.1
divide both sides by -8.63
x= -70
You can set them equal to each other so -3x+4=4x-10 and then you add 3x and 10 on both sides and get7x=14 and then divided both sides by 7 and get x = 2 and check by plugging in and you get -2 for y on both so solution is x=2
1 mile = 1760 yards
Therefore you must times 13 by 1760
13x1760 = 22880
