Okay, so I'm kinda stuck right now. "Last week Amy ran 18 miles more than Anjali. Amy ran 45 miles. Write and solve an equation to find out how many miles Anjali ran."

This is a two-step equation so you know the drill. What I got is x+8=45
Is this right? Or wrong?

= 27

Step-by-step explanation:

x + 18 = 45

   -18      -18

x = 27

Anjali ran 27 miles.

Step-by-step explanation:

So if you make that 8 an 18 it would be right. Hope this helps!

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.
