Answer:
b=2r+4
Step-by-step explanation:
I don't think that you can do this using only one variable because there are two unknown amounts. Blue (b) is Red (r) multiplied by 2 plus 4 more, so the expression is b=2r+4.
So the answer is : 5y + 10 = 6y + 3
5y - 6y +10 = 3
-y= 3-10
-y= -7 Now you are looking for y not -y so you have to multiply or divide both side by (-1). It will be :
(-1) -y = (-1) -7
So:
Y = 7 Final answer.
Y = k / x
2 = k / 4
k = 8
Therefore, the answer for this question would be (4,2)
Answer:
answer is the ratios are not equivalent or not in proportion
Step-by-step explanation:
you can find it by crops multiplication
4/7
8/11
4*11
8*7
44=56
Therefore it is not in proportion
