150(number of tissues)*20(length of tissues) = 3000cm.(total length)
Then to convert it to meters...
1 meter = 100 cm.
3000 ÷ 100 = 30
So 30 meters of paper is needed.
Does that help?
18x/18 = 2/3 • 18
Flip reciprocal of 18 which is 1/18 so it would be 2/3 • 1/18 the 2 and 18 can be simplified when cross multiples so it would then be 1/3 • 1/9 which is x=1/27
Because your gonna elminate the loners and soon your going to substitute them for numbers
Answer:
If y varies inversely as x, then we write it as:
y = k/x
where k is some constant.
If we multiply both sides of this equation by x we get an equation for k:
k = x*y
We are given that y=4 when x=7, therefore:
k = 7*4 = 28
Put this back into our original equation to get:
y = 28/x
