A. Translate each of the following into algebraic expressions. Write the answer in a sheet of paper. 1. One- half x minus 12
2. x diminished by thrice y
3. Twice the sum of x and y
4. The sum of thrice x and y
5. 4 times x decreased by 5
B. Copy the expressions below on a sheet of paper. Encircle the variable/s and box the constant term in each expression.
1. 2x + 10
2. y – 6
3. 3z + 2
4. 4x – 2y + 5
5. 6 (x + 4)

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.
