Answer:
10 inches
Step-by-step explanation:
w = 1/5 P
Multiply each side by 5
5w = 1/5P *5
5w =P
We know the perimeter of a rectangle
P = 2(l+w)
We can set the two equations equal
5w = 2 (l+w)
l =15 inches
We can substitute 15 in for the length
5w = 2(15+w)
Distribute
5w = 30 +2w
Subtract 2w from each side
5w -2w = 30+2w-2w
3w =30
Divide each side by 3
3w/3 = 30/3
w =10
The width is 10 inches
Step-by-step explanation:
25. (+10)-(-6) = 10+6 = 16
26. (-14)-(+7) = -14-7 = -21
27. (-3)-(-9) = -3+9 = 6
28. 0-(-9) = 0+9 = 9
29. (-3)-(+6) = -3-6 = -9
30. (+8)-(-9) = 8+9 = 17
31. (+13)-(+7) = 13-7 = 6
32. (-6)-(-12) = -6+12 = 6
