Answer:
x is equal to 7
Step-by-step explanation:
Because the two horizontal lines are parallel, we know that the angles at which they intersect the diagonal line will be identical.
We also know that on either side of the diagonal line, the sum of the angles between that and either of the horizontal lines will be 180.
In short, we know that the two values given have a sum of 180. With that we can quickly solve for x:
(x + 67) + (x + 127) = 180
2x + 194 = 180
2x = -14
x = 7
X - y = -3
Move constant to the left by adding its opposite to both sides
x - y + 3 = -3 + 3
The sum of two opposites equals
your answer would be: x - y + 3 = 0
Answer:
Here x=10° ,2x=20° ,5x=50°

Answer:
Adult tickets cost $80, children ticket cost $40
Step-by-step explanation:
Given data
let the number of adults be x
and the number of children be y
so
x+y= 40-------------1
The adult tickets
cost 14 dollars and the children’s tickets cost 12 dollars.
14x+ 12y= 720-------2
solve 1 and 2
x+y= 40
14x+ 12y= 720
from 1
x= 40-y
put this in 2 in place of x
14(40-y)+12y= 720
560-14y+12y= 720
collect like terms
-2y= 720-560
-2y= 160
y= -160/2
y= -80
put y= 80 in 1
x+80= 40
x= 40-80
x= -40
Hence Adult tickets cost $80, children ticket cost $40
