Acell phone company charges $35 a month, plus $0.25 per text messages after the first 450 text messages. let c be the total monthly phone bill and t be the number of text messages sent. if sally texted more than 450 times in the following month of july, which of the following equations could she use to determine the total cost of her july phone bill?

a.) c = 35 + 0.25t
b.) c - 450 = 0.25t + 35
c.) c - 35 = 0.25 (t - 450)
d.) c = 35 + 0.25 (t + 450)

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

answer: 2 and 1
