Answer 3

m = number of minutes over 200

19.50 + 0.25m = 29.50

Solve for m

Answer 4

thank you so much :)

Answer 5

I understand how these can be confusing. They're designed to be tricky.

Answer 6

One trick that might help you in figuring out how to setup your equation is to not only name your variable but also name the equation. For example:

The Cost of Last Month's Bill is represented by:
19.50 + 0.25m = 29.50

where m is the amount of minutes over 200.

@AravindG is the answer 5

Answer 10

Nope. Try again.

Answer 11

Is it 40

Answer 12

Are u guessing from options?

Answer 13

Yes I don't know how to solve it I tried but I got 5 from the equation that her gave me

Answer 14

That hero gave me

Answer 15

19.50 + 0.25m = 29.50


Subtract 19.5 on both sides. What do u get?

Answer 16

10

Answer 17

29.50-19.50 is 10

Answer 18

Now divide both sides by 0.25

Answer 19

For easier calculation u can take 0.25 as 1/4

Answer 20

2.5

Answer 21

0.25m=10

Dividing both sides by 0.25?

Answer 22

Try again

Answer 23

.025

Answer 24

M

Answer 25

No.

Answer 26

\[\dfrac{0.25}{0.25}m=\dfrac{10}{0.25}\]

Answer 27

40

Answer 28

How 40?

Answer 29

10\0.25 is 40 according to the calculator

Answer 30

Good :)

Answer 31

Yes 40 is the answer!

Answer 32

Congratulations @Pandabear78963 for figuring out how to the correct result. For future reference, we prefer that you show the steps you took to get to the result you believe is correct rather than just asking if a particular value is correct to avoid the appearance of guessing. For example, instead of asking if 5 is correct, take the following approach:

Say, I believe 5 is correct because...then list the steps you took to get 5. Or more preferably, you can just show your steps then conclude that a certain value is the correct answer.

Answer 33

Exactly. No learning takes place while guessing. And it would not help you at all in a real exam. So better change towards good learning than looking for an answer.
