Step-by-step explanation:
hi I am from India nice to meet you bro
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:
True
Step-by-step explanation:
If the triangle was a right angled triangle then we can prove it using the Pythagoras theorem: c² = a² + b²
c is the largest side and a and b are the two smaller sides of the triangle.
So if this is true then √72² + 154² should be 170:
170² = 72² + 154²
28900 = 5184 + 23716
28900 = 28900
So we have proved using Pythagoras theorem that the triangle is a right angled triangle.
