4h = 100
now divide by 4
h = 25
The least amount is 2 packs.
i know this becaus first i make a lcm chart which looks like this :
8: 8,16,24,32
12: 12,24
i then see that the lcm is 24 and 12+12 is 24 meaning that i will have to buy 2 packs of large plates.
X and y vary inversely means y is inversely proportional to x, this means:
y=k/x, where k is a constant.
We are given that when x=-4, y=7/2, we replace these values to find k.
7/2=k/-4
k= (-4*7)/2=-14
So we have y=-14/x
Therefore, when x=4, y=-14/4= -7/2
