25 - 6 = 19.
15 - 6 = 9 13 - 9 = 4 Therefore, 15 - 6 = 13 - 4.
$4.50
15
6 - (-9) = 15 15 + 2 = 17 17 - 4 = 13 is the answer.
25
c= 120
If you subtract 15 from -6 you get -21. If you worked out the problem on paper, this is what it would look like. -6 - 15 = ? (change the minus to a plus, and change the sign of 15 from positive to negative) -6 + -15 = ? ( now you can add negative 6 plus negative 15 which equals negative 21) -6 + -15 = -21
19 minus 6 equals 13.
If: 6/15 = 2x/25 Then: x = 5
x equals 15
-6 - (-8) = 2
