2420 cups in March
1660 cups in April
2420 + 1660 = 4080
4080/4 = 1020
The cafeteria served 1020 total quarts of milk in March and April
Just do 8 1/3 divided by 5/9 or
25/3 / 5/9
25/3 * 9/5 = 5/1 * 3/1 = 15
So 15 tacos
* = times
/ = divided by
In the form of algebra substitution is the method used in simultaneous equations.
E.g y=2x+5 and y=5x-1
Solve for x and y
Since we know two examples of what y is, we can substitute one y in replacement of the other to get.
2x+5=5x-1 then we solve for x to get:
x = 2 sub this back in to get y = 2(2) +5
y = 9
