5/15 equals 1/3 2/6 equals 1/3 Yes. They are equivalent fractions.
15 plus -3 equals 12 12 divided by -6 equals -2
15-3 times 2 equals 15-6 equals 9.
d/3+3 = 5 d+9 = 15 d = 15-9 d = 6
6x - 3y = 6 y= 2x + 5 replace 2x + 5 for y into the first equation 6x - 3y = 6 6x - 3(2x + 5) = 6 6x - 6x - 15 = 6 0 - 15 = 6 -15 = 6 False So the system has no solution.

3/p = 6 p = 3/6 = 1/2 3/q = 15 q = 3/15 = 1/5 p - q = 1/2 - 1/5 p - q = 5/10-2/10 = 3/10

No! It equals 15, but 9-6=3.
15 over 15 equals One.. 6 over 10..
5X + 6 = 2X + 15 -2X -2X 3X + 6 = 15 -6 -6 3X = 15 ---- ----- 3 3 x = 5 im so smart.
d/3+3 = 5 d+9 = 15 d = 15-9 d = 6

It would be composite because a=1 and b=5 so it would be 3+1+6+5=15, and 15 can be divided by 3 into 5.
