If LllM then the consecutive angles shoud be supplementary(=180)
x-5+2x+5=180
x+2x=180
3x=180
x=60
Answer:x=60
You have to divide and 512/14=36 and 8/14 and that simplified is 36 and 4/7.
6x - 2y = 10
-2y = -6x + 10...reduce by dividing by -2
y = 3x - 5....slope = 3 and y int = -5
y = 3x + 2 ...slope = 3, y int = 2
These lines are parallel. Parallel lines will have the same slope, but different y int's. There is no solution to this because ur lines never intersect.
Mark's answer is correct
From what I can tell, this can't be simplified, because there are no factors of 42 that are perfect squares. I would leave it as the square root of 42.
4(6x+4)-5(3x-6) First you distribute 24x+16-15x+30 then you add like terms so 24x-15x is 9x. 16+30 is 46. So the answer is 9x+46
