Answer:
4/5th of a cup of flour
Step-by-step explanation:
4 cups flour to 5 batches brownies = x cups flour to 1 batch brownies
4 / 5 = x / 1......cross multiply because this is a proportion
(5)(x) = (4)(1)
5x = 4.....divide both sides by 5
x = 4/5
so he used 4/5 of a cup of flour to make 1 batch of brownies <==
<span>Z + 1/z = 2
Multiply 1 by both sides
z+z=2
Add z and z together
2z=2
Divide both sides by 2
Final Answer: z= 1</span>
