Answer:
Step-by-step explanation:
Town B breaks the population down to men women and children. That has meaning, although I did not check to see if the total is the same as what is stated above the total.
For the second question, the answers in order are
does not
cannot
does not.
You can't add things that do not have the same meaning.
does
can
does
You can add these 3 numbers together because all three numbers tell something about the people in town B

Answer: 60 muffins</h3>
=========================================================
Explanation:
x = some positive whole number
2x = amount Helen baked initially
5x = amount Rebecca baked initially
Notice that the ratio 2x:5x reduces to 2:5 after dividing both parts by x.
So (2x)/(5x) = 2/5
Helen then bakes another 12 muffins, bumping the 2x up to 2x+12. The ratio is now 1:2, which means,
(amount Helen bakes)/(amount Rebecca bakes) = 1/2
(2x+12)/(5x) = 1/2
2(2x+12) = 5x*1 .... cross multiply
4x+24 = 5x
24 = 5x-4x
24 = x
x = 24
From here, we then can say,
- Helen = 2x+12 = 2*24+12 = 48+12 = 60
- Rebecca = 5x = 5*24 = 120
Helen baked 60 muffins and Rebecca baked 120 muffins. We see that 60:120 reduces to 1:2 after dividing both parts by the GCF 60.
Furthermore, note how
- 2x = 2*24 = 48
- 5x = 5*24 = 120
- 48:120 reduces to 2:5 after dividing both parts by 24
This helps confirm we have the correct answer.

Answer:
A
Step-by-step explanation:
(-2x^3y^2+4x^2y^3-3xy^4)-(6x^4y-5x^2y^3-y^5)
-2x^3y^2+4x^2y^3-(-5x^2y^3)-3xy^4-6x^4y-(-y^5)
-2x^3y^2+4x^2y^3+5x^2y^3-3xy^4-6x^4y+y^5
-2x^3y^2+9x^2y^3-3xy^4-6x^4y+y^5
-6x^4y-2x^3y^2+9x^2y^3-3xy^4+y^5
