) You and 4 friends evenly divide the total bill at a restaurant. If the total bill is B dollars, write an equation for S, your share of the total bill.
a) How many people are splitting the bill? _
b) Write an equation for S, your share of the bill _

a) 5 people is splitting the bill

b) B divided by 5=S

Step-by-step explanation:

a) You and 4 friends that means 5 people are dividing the bill

b) B equals the total bill then you divided by 5 to split the bill up evenly.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
