X = 4y
3x - y = 70
substitute the x in the second equation with the other half of the first equation.
3(4y) - y = 70
12y - y = 70
11y = 70
y = 6.36 repeating, or 6 4/11
now use this to solve first equation
x = 4 (6 4/11)
x = 25.45 repeating

You need to add up all 3 mixed numbers to find the total laps.
2 + 1/4 + 1 + 1/2 + 3 + 5/8 =
(2 + 1 + 3) + (1/4 + 1/2 + 5/8) =
6 + (2/8 + 4/8 + 5/8) =
6 + (11/8) =
6 + (1 + 3/8) =
7 3/8 laps
A triangle angles all add up to 180 degrees and you have a 90 and 40 degree angle so you are at 130 degrees so the answer is B) x=50 degrees
