To make 90 tortillas, he needs to make 6 batches. 6*15=90
2 cups masa per batch ->. 2 * 6=12 cups Masa
1.5 water per batch -> 1.5. * 6= 9 cups water
Answer and Explanation:
Suppose Waheeda needs x more dollars.
Right now, she has $15. She needs x more, so we add x to 15. The end result we hope to have is $75. So, the equation is:
x + 15 = 75
To solve, we simply subtract 15 from both sides: x = 75 - 15 = 60
Thus, she still needs $60.
Hope this helps!
Do elimination
2x + y = 3
x - y = 3
Add these
3x = 6
X = 2
Plug in 2 for x
4(2) + 2y = 6
8 + 2y = 6
2y = -2
X = 2, y = -1
