Answer:
Step-by-step explanation:
length = 25 in
Perimeter = 86 in
2*(length + width) = 86
2*(25 + N) = 86
Divide both sides by 2
25 + N = 86/2
25 + N = 43
Subtract 25 from both sides
25 + N - 25 = 43 - 25
N = 18

Answer:
C. 3x + x = 67
Step-by-step explanation:
Means Mathew has 3 units and Daniel has 1 unit.
There's 4 units in total.
4x = 67
3x + x = 67
3x is Mathew's DVDs
x is Daniel's DVDs
Obviously it will be 0.25.
Because this number is a rational number not a integer number....
