Answer:
Student ticket: $12, Adult ticket: $14
Equations: 260=10x+10y, 94=2x+5y
Step-by-step explanation:
Set adult tickets as y
Set student tickets as x
First day: Total made is 260 so set that equal to 10x + 10y
--> 260=10x+10y
Second day: Total made is 94 so set that equal to 2x + 5y
--> 94=2x+5y
I find it easier to have simplified terms so simplify (divide by 2) the first equation to get: 130=5x+5y
All you have to do now is solve for the two variables.
94=2x+5y - (130=5x+5y) --> x=12, y=14
Answer:
D
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is

Here [ a, b ] = [ 2, 4 ]
From the table
f(b) = f(4) = 16
f(a) = f(2) = 4, hence
average rate of change =
=
= 6
Answer:
60 cm³
volume of triangular prism : area of base * Length
Given:
- angle between 4 cm and 3 cm : 90°
Find area of base:



Volume :
Answer: 130
Step-by-step explanation:
so 0.7x + x = 221
so 1.7x = 221
divide both sides by 1.7 to get
x = 130
