One square grid has an area of 400.
Another square grid has an area of 256.
The area of the third grid can be:
(squares in third grid) + 256 = 400
OR
256 + 400 = (squares in third grid)
We get this by applying the Pythagorean theorem.
So, the squares in the third grid can either be 144 or 656. And we only have 144 as an option, so that is your answer.
Your final answer is D. 144.
Answer:
The amount of 65 cents per pound flour to use is 40 pounds and the amount of 95 cents per pound flour to use is 60 pounds
Step-by-step explanation:

x ----> amount of 65 cents per pound flour to use
y----> amount of 95 cents per pound flour to use
we know that
---->
----> equation A
----> equation B
substitute equation A in equation B

Solve for x




Find the value of y

therefore
The amount of 65 cents per pound flour to use is 40 pounds and the amount of 95 cents per pound flour to use is 60 pounds
