Trey pays a $6 monthly fee plus 8. Cents per minute. Last month, Trey's long distance bill was $12.72. For how many minutes was
Anit [1.1K]

Hello!

Since Trey pays a flat monthly $6 fee, we can subtract that from the total bill:

$12.27 - $6 = $6.72

That leaves us with a total of $6.72 paid for minutes. We are told that Trey is charged 8 cents per minute of usage. Using the information above, we can create the following equation:

$0.08 x (minutes) = $6.72

Now divide $0.08 from both sides of the equation and simplify:

\frac{0.08}{0.08} x (minutes) = \frac{6.72}{0.08}

minutes = 84

We have now proven that Trey was billed for 84 minutes.

I hope this helps!

WHAT IS THE SLOPE OF THE LINE PASSING THROUGH THE POINTS (-2, -7) AND (3, 5)?????? PLZ ANSWER QUICKLY!!​
jarptica [38.1K]

Answer:

The slope of the line with points A(-2, -7) and B(3,5)  is  m =  (12/5).

Step-by-step explanation:

The two pints are given as A(-2, -7) and B(3,5)

Slope of a line with points (a,b) and (c,d) is given as

m =( \frac{d -b}{c-a} )

So, here the slope of line AB is

m =( \frac{5 - (-7)}{3 - (-2)} )  = \frac{5+ 7}{3 +2}   = \frac{12}{5}

or, m = 12/5

Hence, the slope of the line with points A(-2, -7) and B(3,5)  is (12/5).
