Answer:
5 cups of flour.
Step-by-step explanation:
I know the wording of the problem may be confusing at first, but if you look at it a little bit, it's just multiplication and division.
To start,
12 biscuits require 2 cups of flour,
meaning that 6 biscuits (half of the original) only require 1 cup.
<u>(12/2 = 6)</u>
Next,
We need to find how much flour is in 30 biscuits.
We know that 1 cup is in 6 biscuits, and if you were to find how much was in 30 biscuits, you would just need to divide 30 by 6.
<u>(30/6 = 5)</u>
5 cups of flour would be your answer.
To put it mathematically,
(12/2 = 6), (30/6 = 5)
Answer:

Step-by-step explanation:

-ab>0 is the answer cause the others make 0 not to be simplified
<span>7x - 2 = 2y
7x = 2y + 2
so
</span>7x = 2y + 2<span>
3x = 2y - 1
----------------subtract
4x = 3
x = 3/4
</span>7x - 2 = 2y
7(3/4) - 2 = 2y
21/4 - 2 = 2y
21/4 - 8/4 = 2y
13/4 = 2y
so
y = 13/4 * 1/2
y = 13/8
answer
<span>(3/4, 13/8)</span>
