Cost per friend will be total cost of cab ride / number of friends
so z = 12.75 / y
Answer:
23, 33, and 92
Step-by-step explanation:
If the three numbers are x, y, and z, then:
x + y + z = 148
y = x + 10
z = 4x
Substitute:
x + (x + 10) + (4x) = 148
6x + 10 = 148
6x = 138
x = 23
y = 33
z = 92

hey u have any pictures that can explain it
On the sheet, it's not even asking you for the dimensions.
It's just asking you to set up the <em>equation that you would use</em>

==========================================
Call the width of the window 'W' .
We know that the length is 5 feet more than the width, so the length is (W + 5).
The area is (length times width).
Area = (W + 5) times (W).
36 = (W + 5) W
36 = W² + 5W
Subtract 36 from each side:
W² + 5W - 36 = 0
That's choice-4 .
