Answer:

B. 300 Copies

Step-by-step explanation:

So inplace of the copies you input the value x. Then, create an equation...

3,255= 13.75x -2.90x

3,255= 10.85x

Next you have to isolate x

3,255/10.85 = 300

so, 300=x

2. Gerald was given the following problem to solve for the length of the "?". He has made a mistake in his work.
Degger [83]

Answer:

x = 18.7

Step-by-step explanation:

Gerald's answer is almost correct.  

He just needs to switch the 14 and the x.

it should be

24/x = 18/14

solve for x by cross multiplication

18x = (24)(14)

18x = 336

x = 18.7

**HELP!**
mr_godi [17]
If two figures or lengths are similar, then the ratios of the corresponding lengths are equal.
Thus, 8/32 =5/x
          8x = 160
            x = 20 feet
Therefore, the length of the flag pole was 20 feet long
