Let x be the number of tickets sold to adults and y the number sold to students:
x + y = 315. But we know that y was double x, then :
y = 2x
Plug the value of y (in the 1st equation) by 2x:
x+ 2x = 315
3x = 315
and x = 105 (which is the number of tickets sold to adults
Answer: H = 20
Step-by-step explanation:
To find the hypotenuse , we will use Pythagoras theorem, which states that
The square of the hypotenuse = the square of the adjacent + the square of the opposite.
Since , we are dealing with isosceles right triangle , this means that :
both the adjacent and the opposite are equal, using the formula to find the hypotenuse , let H represent the hypotenuse , then
=
+ 
= 400 + 400
= 800
Take the square root of both sides
H = 
can be written as
x
Therefore :
H =
x
H = 20x 
H = 20

Answer:
y=-4x+3
Step-by-step explanation:
as x=0
put in y= -4x+3
y= -4(0)+3
y=3
now put x=1 in y= -4x+3
y= -4(1)+3
y= -1
now put x=2 in y= -4x+3
y= -4(2)+3
y=-5
