The senior class had a car wash to raise money for the senior trip. It cost them $35 for supplies. They washed 75 cars
and charged $6 for each car.
Which of the following expressions represents the money they raised for their trip?
$35 + 75 - $6
$35 - 75. $6
75 . $6 - $35
75 - $35 - $6

75 x $6 - $35

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.
