600/100 as a mixed number would be 6
<h3>
Answer: G) -2</h3>
=======================================================
Explanation:
I'm assuming you meant to say (a+y)^2 + 2y
Replace each copy of 'a' with 5. Replace each copy of 'y' with -3. Use PEMDAS to simplify.
(a+y)^2 + 2y
(5 + (-3))^2 + 2(-3)
(5-3)^2 + 2(-3)
(2)^2 + 2(-3)
4 + 2(-3)
4 - 6
-2
So (a+y)^2 + 2y = -2 when a = 5 and y = -3.
Answer:
find the percentage equal to 70/80
First, plug in 448 for y:
448=7x+294
Secondly, subtract 294 from both sides to isolate x:
154=7x
Divide both sides by 7:
22=x
Refine:
x=22
The answer is D)22
