Answer:
$697
Step-by-step explanation:
Given that :
Weekly earning = $375 plus 7% commission on sales
Earning if she sold $4600 worth of merchandise
Commision on sales = 7% of 4600
Commission = 0.07 * 4600
Commission on sales = $322
Total earning = $375 + $322
Total earning = $697
Steps:
1. Do a proportion
2/3 times x/12
2. Do 12 times 2=24
3. Divide 24 by 3
4. Your answer is 8 girls
Or you could do it this way
Steps:
1. You could have just multiplied the 2 by a 4 to get 8.12 boys divided by 3 boys is 4. That means you multiple the two by 4 to get the girls.
X-the $5 bills
y-the $10 bills
x+y=20
5x+10y=120
It's a system.

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.
