2:9 = 11
In total there will be 11 cups of solution.
2:9 = 11
?:36 = ?
Divide
36 / 9 = 4
Now that you have found the scale factor, multiply
2 × 4 = 8

Answer: its k2 because the division bar means subtract
Step-by-step explanation:
Since y=-3x -2 we shall replace this value of y in the second equation to get ..
5x+2(-3x-2)
=5x-6x-4
=-x-4,take the -4 to the other side and so we shall have
-x=4 ,divide both sides by -1 to get x=-4
So we shall go back to our first equation and replace x with the value we have so we shall get...
Y=-3(-4) -2
Y= 10
