10d+5n=220
divide both sides by 5
2d+n=44
d=13+n
sub 13+n for d in other equatin
2(13+n)+n=44
26+2n+n=44
26+3n=44
minus 26 both sides
3n=18
divide both sides by 3
n=6
sub back
d=13+n
d=13+6
d=19
19 dimes
6 nickles
Step-by-step explanation:
First divide 1100 by 2
550
Now that would be the amount the both of them would have to pay if they were splitting it equally. Since there not add 250 to 550.
250+550=800
Finally subtract 250 from 550
550-250=300
Jake has to pay $550
Danny has to pay $300
Answer: 20%
1/(1+4) = the answer
its just the amount of lemon juice over total volume
Answer: First, you identify how many rises and runs the line is from each point on a graph (intersection). Then you take the y's and the x's and do y2-y1/x2-x1 to get the slope!
730/27 or improper fractions 27 1/27
