Olivia and ray walk to school. olivia walks 1/4 of a mile to school. her walk is 2/3 of the distance that ray walks to school. what is the total distance, in miles that ray walks to school?
a) 1/6
b) 3/8
c) 5/12
d) 11/12

Ray walks to school 3/8 miles (0.375 miles)

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
