I just told you the answer it is -5
Answer:
If 0.25 oz of yeast is used, then 50oz of flour is needed.
It would require 0.5 oz of yeast for 90 oz the flour.
Step-by-step explanation:
We know that the proportion of yeast (y) and flour (f) is 1: 200 when a maximum of 30 servings of bread is made. This is:

So if we use 0.25 oz of yeast:
if 0.25 oz of yeast is used, then 50oz of flour is needed.
If you make 60 servings of bread with 90 oz. Of flour, then you should keep the following ratio:

So, if we use f = 90 0z of flour:
It would require 0.5 oz of yeast.
To isolate b, add a and subtract c to the entire equation:
D - a + c = -b
Muliply b by -1 to eliminate the negative:
-D + a - c = b
Answer:
x = 41/3
y = 199/3
Step-by-step explanation:
Solve using system of equations
x is smaller number, y is larger
eq1> y + 2 = 5x > y = 5x - 2
eq2> 80 = x + y > y = 80 - x
equate
80 - x = 5x - 2
Solving:
x = 41/3
y = 199/3
