A cell phone company charges a flat rate of $2.50 per month, with an additional charge of $0.15 per minute. How many minutes did Laura talk on her cell phone if her monthly bill was $72.25?

465 minutes

Step-by-step explanation:

First things first, you have to make an equation! It would be...

2.50+0.15m=72.25

Keep in mind that m stands for minutes.

Now let's solve it!!

First let's subtract 2.50 from both sides.

0.15m=69.75

Now, let's divide 0.15 on both sides!

m= 465

465 minutes!!

Hope this helped!! :D

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
