So, x + y = 42 and y - x = 5;
Then, y = x + 5;
Finally, x + x + 5 = 42;
2x + 5 = 42;
2x = 37;
x = 18.5;
y = 18.5 + 5;
y = 23.5;
<span>C = AB + D
AB = C - D
B = (C-D)/A
B = C/A - D/A</span>
2/4 = 0.5
3/4 = 0.75
7/8 = 0.875
3/8 = 0.375
There are 20 nickels in 1 dollar so you would do 20 x 5 which is 100
