13x + 15 = 11x - 5 2x = -20 x = -10
11x + 8 = 8x + 20 3x + 8 = 20 3x = 12 x = 4
14/20 = 7/10 = 0.7 = 70%
Points: (0, -2) and (20, 42) Slope: 11/5 Equation: 5y = 11x-10 or as y = 2.2x-2.
It is: 14/20 = 7/10
13x + 15 = 11x - 5 2x = -20 x = -10
If that's - 11x - 20, the answer is (4x + 5)(x - 4). If that's + 11x + 20, it gets ugly in a hurry.
-11x=22011x=-220x=-220/11=-20
11x + 8 = 8x + 20 3x + 8 = 20 3x = 12 x = 4

If you mean: 3x squared -11x -20 = 0 Then: x = -5 or x = 4/3
7/10 of 20 = 20*7/10 = 14
7/10 of 20 is 14
$10 - $20
I presume that you mean 5x + 3y + 20 = 0 and 2x - y - 14 = 0. First put the formulae in the form y = mx + c. 3y = -5x -20 y = -5/3 x -20/3 and y = -2x + 14 Substitute the second formula into the first -2x - 14 = -5/3 x -20/3 -6x - 42 = -5x - 20 -42 = x - 20 x = -22 Substitute into equation y = -2x + 14 y = -2 x -22 + 14 y = 44 + 14 y = 58 Therefore the two lines meet at point (-22, 58).
14/20 = 7/10
14/20 = 7/10 = 0.7 = 70%
