Answer:
B
Step-by-step explanation:
2x + 4y = 6x - y
4y + y = 6x - 2x
5y = 4x
(4,5) when x=4, y=5
5(5) = 4(4)
25 = 16
is a false statement, so not (4,5)
(5,4) when x=5, y=4
5(4) = 4(5)
20 = 20
is a true statement, so yes
Answer:
<u>So, the way a ratio works is </u><u>"for every 1 of this, we have 4 of this"</u><u> for example. (the ratio I just described would be 1:4.) </u>

I believe I've seen this question before. If the ratio of dolls to teddy bears is 9:3 then for every 9 dolls you have 3 teddy bears.
So, since we have 240 dolls and a 9:3 ratio to teddy bears, all we have to do is take how many dolls we have (240) and divide it by 3 to see how many teddy bears we have.
So:
240 ÷ 3 = 80
If your ratio is 9:3, then 80 is your answer.

8 (x - 3) + 8 = 5x - 22
First, expand. / Your problem should look like: 8x - 24 + 8 = 5x - 22
Second, simplify 8x - 24 + 8 to 8x - 16. / Your problem should look like: 8x - 16 = 5x - 22
Third, subtract 5x from both sides. / Your problem should look like: 8x - 16 - 5x = -22
Fourth, simplify 8x - 16 - 5x to 3x - 16. / Your problem should look like: 3x - 16 = -22
Fifth, add 16 to both sides. / Your problem should look like: 3x = -22 + 16
Sixth, simplify -22 + 16 to -6. / Your problem should look like: 3x = -6
Seventh, divide both sides by 3. / Your problem should look like: x =
Eighth, simplify

to 2. / Your problem should look like: x = -2
Answer:
x = -2
Hi there, 2.5 to the third power=2.5*2.5*2.5=15.625, Therefore, the answer is D. 15.625
