Let x=large boxes and y=small boxes.
x+y=110
60x+35y=5100
____________
You need to cancel out one of the variables to solve for one. Let's cancel out y.
-35(x+y=110)
-35x-35y=-3850
60x+35y=5100
____________
Add the two equations.
25x=1250
x=50
_____________
Plug in 50 for x into one of the equations to solve for y.
50+y=110
y=60
_____________
50 large boxes
60 small boxes
1,8 is the mid point of these two numbers
Answer:
-1, 9/18, 0.5
Step-by-step explanation:
I put into decimials
-1 = -1
9/18 = 0.5
1 8/16 = 1.5
(I think that is IXL, good luck!)
The answer is C because when you rotate 90 degrees clockwise (x,y) becomes (y,-x)
