X = advance
y= same day
x+y=70
30x+15y=1650
--------------------------
30x+15y=1650
- x+y=70 (x15) -> 15x+15y=1050
--------------------------
30x+15y=1650
-15x+15y=1050
--------------------------
15x=600
x=600/15
x=40
so now u can insert the price of x AKA the price of the advanced ticket to find our the price of the same day ticket.
x+y=70
so
40+ y=70
y=70-40
y=30
x = advance =40
y= same day =30
Answer:
x=5, y=3
Step-by-step explanation:
5^3=125
3^3=27
125+27=152
Answer:
The first one
Step-by-step explanation:
5x-6y=10
-5x -5x
-6y=-5x + 10
y-yV1=m(x-xV1)
y+1 = -5 (x+6)
destribute the -5 to the parinthease.
y+1 = -5x - 30
-1 - 1
y= -5x -31
Answer:
P(d) = 62 - 2d
Step-by-step explanation:
