Answer:
x=-3
Y=-5
Step-by-step explanation:
2x-y=-1 ×2
3x-2y=1. ×1
4x-2y= -2
3x-2y=1
eliminate y by subtracting
Answer:
The general admission ticket number is 160 and the upper box ticket number is 136
Step-by-step explanation:
In this case we can solve it using a 2x2 system of equations, like this:
let x be general admission tickets number
let y be upper box tickets number
So:
6.5 * x + 10 * y = 2400
x + y = 296 => x = 296 - y
Replacing, we are left with that:
6.5 * (296 - y) + 10 * y = 2400
1924 - 6.5 * y + 10 * y = 2400
10 * y - 6.5 * y = 2400 - 1924
3.5 * y = 476
y = 476 / 3.5
y = 136
Now to calculate x:
x = 296 - 136
x = 160
The general admission ticket number is 160 and the upper box ticket number is 136
An acute angle is one that measures LESS than 90˚
An obtuse angle is one that measures between 90˚ and 180˚
A reflex angle is an angle that measures between 180˚ and 360˚
There are other many types of angles such as alternate angles and corresponding angles, but those 3 are the main ones.
