Rules is that:
a+b>c
a+c>b
b+c>a
let a = 5
let b = 7
let c = 9
5+7>9
5+9>7
7+9>5
Therefore, this satisfies the rules of a triangle
The answer is 14/20 or you can simplify it to 7/10 probability of choosing a red or blue stamp.

Answer:
$18
Step-by-step explanation:
Let's subtract the lunch from the trip total to get the remainding cost!
36.50 - 9.50 = $27
Now let's set up an equation to figure out the amount of the entrance ticket and the gift coupon!
let's have x = the entrance ticket
27 = x + 1/2(x) -----------> 1/2 is next to x, because the gift coupon is 1/2, or 50% of the entrance ticket! Now solve for x!
27 = 3/2x
(2/3) 27 = 3/2x (2/3)
18 = x, so the entrance ticket is $18!
