4. Would the value of (18-6)divided by3 + 2
change if the parentheses were
removed? Explain.

answer: options?

step-by-step explanation:

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

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.
