Answer: Choice A</h3>
0.10d + 0.05n = 2.25
d = 2n
================================================
Explanation:
n = number of nickels
d = number of dimes
we have twice as many dimes as nickels, so we could have something like 18 dimes and 9 nickels. Algebraically we would write d = 18 and n = 9. The equation that fits this is d = 2n. The answer is between A and B at this point.
We rule out choice B since the 0.05d is incorrect. It should be 0.10d to represent the total value of all the dimes.
Choice A is correct
d = number of dimes
0.10d = value of all the dimes in dollars
n = number of nickels
0.05n = value of all the nickels in dollars
0.10d + 0.05n = total value from both coins combined
2.25 = total value from both coins combined
0.10d + 0.05n = 2.25

Answer:
Ok to make this easier for us we should switch these equations into y=mx+b so that it's easier for us to identify the slope and y-intercept:
to switch into y=mx+b form do this:
3x-y=5
-y=5-3x
y=-5+3x
y=3x+(-5)
2y-15x=8
2y=8+15x
y=4+7 1/2x
y=7 1/2x+4
THe slope of any line in y=mx+b form is m. Therefore in this equation:
y=3x+(-5) 3 is the slope
The y intercept of any line is the +b:
y=7 1/2x+4 -therefore 4 in this equation is our y intercept.
Now we can construct our equation in y=mx+b then into standard form (Ax+By=C)
since 3 is our slope and 4 is our y intercept the equatuon is :
y=3x+4
NOw all we need to do is move this into standard form:
y=3x+4
-3x+y=4
-3x+y=4 is your final answer
-hope this helped
