x + y= 9 and x - y= 3
rearrange the second equation:
x - y= 3
x = 3 + y
x -3 = y
substitute y with "x-3" in the first equation and solve
x + y= 9
x + (x-3)= 9
2x -3 = 9
2x = 12
x = 6
you could also start with the first equation and substitute y in the second.
graphically speaking, it's the intersection point of to lines, at least the six-part of the point.
40/x=100/190 40/x=100/190
(40/x)*x=(100/190)*x
40=0.526315789474*x
(0.56315789474) to get x
40/0.536315789474=x
76=x
x=76 now we have 190% of 76
Answer:
25 mini loaves
Step-by-step explanation:
Using the first set you can divide and tell that 1 cup of flour is equal to 2.5 mini loaves, applying that to the other set you can inquire that it's true. So therefore what you need to do is multiply 2.5 times the amount of flour you are using.
10 cups = 25 mini loaves
