(t-7)/w = (-3-7)/-2 = -10/-2 = +5 ( minus over minus = plus)
3x2 - 2x - 5 = (3x - 5)(x + 1) = 0 gives a solution of x = 5/3 or -1. Was that what you wanted?
In order to answer, we must know what bequals.
10 - 5 = 5
-8

3 fifteenths minus 5 fifteenths equals minus 2 fifteenths.
-2
5 - (-3) = -8
3 - 5 = -2
5 tenths minus 3 hundredths equals 0.47.
-3 minus -2 is -1.
The answer is "FALSE".
8
3 - x = 8x = 3 - 8x = - 5
you do 3 plus 5 first then you get 8 you have to find out what minus 7 equals 8
