The equation for Louis's purchase is: 
The equation for Kate's purchase is: 
The equation for Biff's purchase is: 
Step-by-step explanation:
First of all we have to define variables for each item involved in the purchase
Let x represent burger
y represent soda
z be the slice of pizza
Then
"Louis bought a burger and soda for $8"
"Kate purchased a slice of pizza and soda for $9"
"Biff purchased a burger, a slice of pizza and a soda for $13.50"
The equation for Louis's purchase is:
The equation for Kate's purchase is:
The equation for Biff's purchase is:

• x+1.793= 2.42
x-1.793= 2.42-1.793 FALSE
• 5.25x = 15.75
Solve for x, by dividing both sides of the equation by 5.25
x = 15.75/5.25
x = 3 TRUE
• The equation x = 2.4 *11.62 can be rewritten as x = 11.62 * 2.4. TRUE
• The solution to the equation x + 9.43 = 16.09 is x = 6.66.
x+9.43 = 16.09
Subtract 9.43 from both sides of the euqation:
x-9.43+9.43= 16.09-9.43
x = 6.66 TRUE
Answer:
Limit is 2
Step-by-step explanation:
The last term approaches zero as n approaches infinity so the fuction approaches 2.
Well if you're asking for it to be in a fraction, then it's already in its simpliest form. but for a decimal, it would be 0.8833
9(3+5) is equivalent because factoring a 9 out of both 27 and 45 leaves us with 9(3+5).
