Abox contains 8.75 in nickels, dimes, and quarters. there are 51 coins in all, and the sum of the numbers of nicole’s and dimes is 3 less than the number of quarters. how many coins of each kind are there

answer:

there are 17 coins of each kind

step-by-step explanation:

divide the 51 coins into three groups.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

the answer for this question is 38
