You divide you total tickets by 2. so you would take 20 and divide it by 2= $10 for 20 tickets. So the rule is divide the total number of tickets by 2.
X=275+55= 330 biked
y=275-55= 220 bus
Answer:
GH = 17 units
GI = 39 units
HI = 39 units
Step-by-step explanation:
We are given the following information in the question:
Triangle GHI is an isosceles triangle.
![GI = HI](https://tex.z-dn.net/?f=GI%20%3D%20HI)
The measures of side are:
![GH = 3 + x\\HI = 4x-17\\GI = 6x - 45](https://tex.z-dn.net/?f=GH%20%3D%203%20%2B%20x%5C%5CHI%20%3D%204x-17%5C%5CGI%20%3D%206x%20-%2045)
It is given that
GI = HI
![4x - 17 = 6x -45\\6x - 4x = 45-17\\2x = 28\\x = 14](https://tex.z-dn.net/?f=4x%20-%2017%20%3D%206x%20-45%5C%5C6x%20-%204x%20%3D%2045-17%5C%5C2x%20%3D%2028%5C%5Cx%20%3D%2014)
Thus, the measures of three sides are:
![GH = 3 + x=14+3 = 17\\HI = 4x-17 = 4(14)-17 = 39\\GI = 6x - 45=6(14) - 45 = 39](https://tex.z-dn.net/?f=GH%20%3D%203%20%2B%20x%3D14%2B3%20%3D%2017%5C%5CHI%20%3D%204x-17%20%3D%204%2814%29-17%20%3D%2039%5C%5CGI%20%3D%206x%20-%2045%3D6%2814%29%20-%2045%20%3D%2039)
Use the formula for the volume of a triangular pyramid: V=13Ah , where A = area of the triangular base, and H = height of the pyramid.
Get all the x terms on one side, and the w on the other.
Add 37x on both sides to get 56x+rx=w.
Use the distributive property backwards to get x(56+r)=w.
Divide by 56+r on both sides to get x=w/(56+r)
