Multiplying or dividing both sides by a negative number reverses the inequality.
Answer:
<c=152°
Step-by-step explanation:
We know that A and B are equal because it's an isosceles triangle.
x-14=x/2
2(x-14)=x
2x-28=x
x=28
<A=x-14=28-14=14
<B=x/2=28/2=14
<C=180-14-14=152°
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
