3(4x - 4) - 7x, when simplified, is 5x - 12. So your answer would be A, or the first one.
The estimated answer is 11. First you round 16.8 to 17 because the decimal is above 5. Then you round 5.94 to 6 because the first decimal place is greater than 5. Lastly you subtract 17 minus 5 to get 11.
45x+angle trs = 180 straight line
angle trs = 180-45x
angle trs + angle t + angle tsr = 180 (sum of angles in a triangle =180)
(180-45x) + 25x + 57+x = 180
combine like terms
180 +57 -45x+25x+x=180
237-19x=180
subtract 237 from each side
-19x =-57
divide by -19
x=3
27 - 9x +15y
Factor out common term 3 :
3(9-3x+5y)
hope this helps!
