Translate each phrase into an algebraic expression. four inches less than kimi a. x – 4 c. x + 4 b. x ¸ 4 d. 4 – x

a) x - 4

Step-by-step explanation:

Given: four inches less than Kimi

Let "x" be Kimi

Four inches less than means subtraction

Therefore, it is x-4.

a) x - 4

Thank you.

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.

the answer to your question is b.
