Paige spent $7.55 on some report covers and one lanyard at the spirit shop. each report cover costs $0.35 and the layard cost $6.50.how many report covers did paige buy? write and solve an equation without decimals.

The answer is 3.

Step-by-step explanation:

7.55-6.50=1.05

1.05/.35=3

42.4

step-by-step explanation:

convert to decimal

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.
