A dime is a ten cent coin while a quarter is a 25 cent coin. The total of the money should be $8.40. Let x be the number of dime and y be the number of quarter. The equation that would best represent the given problem is,
                                  0.1x + 0.25y = 8.40
                                      x + y = 45
The values of x and y are 19 and 26, respectively. Thus, there are 19 dimes and 26 quarters.

What is the slope? Show work as well please.
stealth61 [152]

To find slope you want to do the rise over the run. First you identify your coordinates which in this case are (0,0) and (2,1). Then you do the rise over the run or in a fraction out the number of how many units you go up (rise) and how many units you go accross (run). So for this slope you would put your rise of 1 over your run of 2 and your answer would be s=1/2 (s stands for slope)
