If 8 widgets equal 4 curlicues and2 curlicues equal 3 goof-ups,then
16 widgets equal how many goof-ups?

Answers

Answer 1
Answer: so 8w=4c and 2c=3g. divide the first equation by 2 and you get 4w=2c. merge the two equation give you 4w=2c=3g, or 4w=3g. multiply 4 on both sides give you 16w=12g. So 16 widgets equal how 12 goof-ups?

I am needing to know the answer to 3/7 of what number is 9?

Answers

In math, "of" almost always means "times".

So your question is:  3/7 times (the number) = 9

Multiply each side of that equation by  7 :   3 times (the number) = 63

Divide each side by 3 :              The number = 21
The best thing to do is to find out what 1/7 is.
9/7= 1.28
1.28x3= 3.84
Therefore 3/7 of 9 is 3.84
Hope this helps :)

remember
you can do ANYTHING to an equation as long as you do it to BOTH SIDES
also
a/a=1
ab/ab=1

so
we want to solve for h or 1h

T=pirh
divide both sides by pir (since pir/pir=1)
T/(pir)=1h
T/(pir)=h


C
T=πrh
πrh=T
(πr) * h=T
h=T/πr

Answer: C    h=T/πr
