Answer:
7. Approximately 402.7 inches or 2pi times 64
8. 31.83 To solve this you know 2pi r is an equation for the radius. 2πr=200 and r=200/2π=100/π= 31.83.
9. The one with pi in the equation because 3.14 is only a piece of pi but the symbol represents the whole number which goes on forever.

I'm assuming this is a <em>combining like terms</em> question, in which case the answer would be 6n - 3c.
<u><em>Step-by-step explanation:</em></u>
I'm guessing your teacher wants you to combine the like terms, and 1n plus 5n = 6n, minus 3c is the answer, which is 6n - 3c. If your teacher wanted you to solve for each variable, you can't do that because you don't have enough information, and there's an infinite number of solutions.

Answer:
it's 4.5
Step-by-step explanation:
you have to find the difference between each number and the mean. then you find the mean of that sum
Since rectangle ABCD is similar to HGFE, the ratios of the lengths of their corresponding sides are equal. We can infer form our picture that AD is corresponding to EH and DC is corresponding to HG, so lets find the ratios of those corresponding sides and establish a proportion to find the length of HG:
We know that
,
, and
, so lets replace those values in our proportion:
We can conclude that the length of the segment
HG is 9.
