System of Equations
For the problem to solve we'll use the following variables:
x = number of the early bird tickets sold
y = number of the regular tickets sold
Haley sold a total of 20 tickets, thus:
x + y = 20 [1]
Early bird tickets cost $10 and regular tickets cost $15, thus the total money collected is:
10x + 15y = 225
Dividing by 5:
2x + 3y = 45 [2]
We have to solve the system of equations [1] and [2].
Multiply [1] by -2:
-2x - 2y = -40 [3]
Add [3] to [2]:
-2x - 2y +2x + 3y = -40 + 45
Simplifying:
y = 5
Substituting in [1]:
x + 5 = 20
Subtracting 5:
x = 20 - 5
x = 15
Solution: Hayley sold 15 early bird tickets and 5 regular-priced tickets
The order pair solution is (15,5)
Answer:
22.05
Step-by-step explanation:
21/2 has 5 halves
10.5 divided by 5= 2.1
2.1= 1/2 2.1 x 10 = 21
2.1 / 2 = 1.05
21 + 1.05= 22.05

Answer:
Step-by-step explanation:
<em>The correct question is</em>
If f(x)=3x-1 and g(x)=x+2, find (f-g)(x)
we know that
(f-g)(x) is equal to subtract the function g(x) from the function f(x)
so
substitute the given functions
Remove the parenthesis
