Kayleigh has a collection of quarters and nickels. a) write an equation to represent the total value of the coins. define your variables.
b) if the total value of the coins is $5.59 and kayleigh has 17 quarters, how many nickels dies she have?

the answer is 48m^2!

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.
