Percent means parts out tof 100 so 15%=15/100
divide by 5/5
3/20=lowet terms
Perimeter = 30 inches
Length = 3x
Width = X
P = 2L + 2W
30 = 2(3x) + 2(X)
30 = 6x + 2x
30 = 8x
30/8 = 8x/8
3 6/8 = 3 3/4 = X
X = 3.75 inches
The width is 3.75 inches and red length would be 3 times as much or 3(3.75) = 11.25 inches.

Step-by-step explanation:
I HOPE THIS HELPED!
The y-value changes sign when a point is reflected across the x-axis. The reflected point is (-3, -7).
The more painstaking way would be to divide the spinner up into 100 pieces, and shade in 5 of those pieces. Since 5/100 = 0.05 = 5% this means that landing on any of the 5 pieces has a 5% chance of happening.
A better way to do this is to use 20 slices instead. This works because 5/100 reduces to 1/20 (divide top and bottom by 5). Instead of shading in 5 slices, Mark should shade in 1. If you use a calculator, you should see that 1/20 = 0.05 = 5% as well.
The second option is more practical but even then a spinner with 20 sections is still a lot. I think it might be better for Mark to pull random numbers out of a hat, or let the computer generate random numbers.
