each day, the sum of the average times spent on grooming for 20- to 24-year-old women and men is 86 minutes. the difference between grooming times for 20-to 24-year-old women and men is 12 minutes. how many minutes per day do 20- to 24-year-old women and men spend on grooming

eve and marks ratios are equivalent

step-by-step explanation:

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?

step-by-step explanation:

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.
