Loosely, "varies inversely" means that as one quantity increases, the other decreases. Specifically, if x and y vary inversely, then y = k/x where k is some constant (a particular number).
Another way to write that relationship is xy = k. To find the value of k for this problem, you need a numbers for x and y that go together.
Suppose x = number of children and y = number of candies (it doesn't matter what order these go in as long as you keep track!).
"When 12 children are present, 140 pieces of candy are consumed." So when x = 12, the value of y = 140.
xy = k
(12)(140) = k
1680 = k
Now, when x = 8 children,
8y = 1680
y = 210
Your answer should be 168.40
Answer:
x = 2
Step-by-step explanation:
<em>Distribute</em>
3 (−4) = 2 (−2+1)
3 − 12 = 2 (-2x +1)
<em>Distrubute again</em>
3x - 12 = -4x + 2
<em>Add twelve to both sides of the equation</em>
<em>Simpfly</em>
3x = -4x + 14
<em>Add 4x to both sides of the equation</em>
<em>simpfly</em>
7x = 14
<em>Divide both sides of the equation by the same term</em>
<em>Simpfly</em>
x = 2
