Ashley is wrong. I have no clue what a placement chart is but I'll solve it anyway.
(5/10)x100 = (5x100)/10 = 500/10 = 50
Uhm I think you forgot something
x+y=120_______1
x=4*y_________2
x=4y
substitute 4y for x in equation 1
`4y+y=120
5y=120
eliminate the coefficient of y
y=120/5
y=24
now,input 24 for y in equation 2
`x=4y
x=4*24
x=96
thus, the numbers are
96 and 24

Answer:</h3>
19.5 inches
<h3>
Step-by-step explanation:</h3>
Let r represent the length of one of the sections of rope (in inches). Then the total length of the original rope is ...
... 8r +28.9 = 184.9
... 8r = 156 . . . . . . . . . . . . subtract 28.9; next, divide by 8
... 156/8 = r = 19.5
The length of each of the sections is 19.5 inches.
