Answer:
Q+D = 65, multiply both sides by 2525Q + 25D = 162525Q + 10D = 950 subtract to get 15D = 675 D = 675/15 = 135/3 = 45 dimes Q = 65-45 = 20 quarters25(20) + 10(45) = 500+450 = 950
They are the same because the first one you do 2 x 3 which equals 6 and then you do 2 x 6 which equals to 12. Then you do 12 x 6 which equal to 72. Then for the second one you do parentheses first so that 2x6 which equals 12 and then you x 6 so now it would be 12 x 6 equal to 72. SO YOUR ANSWER IS THEY ARE THE SAME
The grouping has changed in the equation.
3(mn) = (3m)n
This is the associative property of multiplication.
