You would use 48 cans of pineapple juice for this fruit punch recipe.
Step-by-step explanation:
Let the first number be <em>x</em>
Let the second number be <em>y</em>
<em>x</em> = y - 9
3x = 4y + 12
3x - 4y = 12
3(y - 9) - 4y = 12
3y -4y - 27 = 12
-y = 12 + 27
-y = 39
y = -39
x = y - 9
x = -39 - 9 = -48

Answer: x = 65</h3>
==============================================================
Explanation:
We have a pair of vertical angles. The angles do not need to align vertically to be considered vertical angles. They simply just need to be opposite one another in this X configuration as the diagram shows.
Vertical angles are always congruent.
Set the expressions equal to one another. Solve for x.
2x+15 = 145
2x = 145-15 ... subtracting 15 from both sides
2x = 130
x = 130/2 .... dividing both sides by 2
x = 65
I^2 = -1
-6(3i) = -18i
-18i(-2i) = 36(i^2)
36(i^2) = 36(-1)
36(-1) = -36
i^2 = -1
2(3 - i)(-2 + 4i) :(do foil)
2(-6 + 12i +2i - 4i^2)
-2 (-6 + 14i +4)
-2(-2 + 14i)
4 -28i
4-28i is your answer
hope this helps
