Question

Is the equation true, false, or open? Explain.

9p+8=10p+7

Answer 1

It's true because if you subtract 7 from both sides, you will 9p+1=10p Then, when you subtract 9p from both sides, you will have 1=1p so it's true

Answer 2

It is open because true or false statements cannot have variables.

Answer 3

Okay, Kell1170, is Math>philosphy right in any way?

Answer 4

Well, if you divide by 1 on each side you have 1=p, which works, because when you plug it in, you have 9(1)+8 = 10(1)+7 So, 17=17.

Answer 5

17 = 17 is a true sentence. 9p+8=10p+7 is neither true nor false.

Answer 6

okay I just finished working the problem out, you are correct, so it appears! GO Girl!!!!!! Thank you sooo much!

Answer 7

It asked if the equation was true or false, which you can't determine until you work it out.

Answer 8

That's why it would have been an open statement, because it's undetermined until you solve for the variable

Answer 9

You're welcome!

Answer 10

exactly, i just was confused as to where the heck to begin, I am soo greatful for you right now!

Answer 11

Math>philosophy, if you went that route, every question would be open, which I highly doubt is the point of the problems. So, you must solve for the variable.

Answer 12

Every question is open..I thought the point of the problem was determine logic/sets
