Question

Is this equation true, false or open?

9p+8=10p+7

A) Open; There is a variable
B)True; The expressions are the same value of the variables.
C) False; The expressions are never the same.

Please help!

Answer 1

try to solve it first

Answer 2

Well do I start off by subtracting 9p from 10p? I just don't get these types of equations that much.

Answer 3

Collect like terms and solve for p

Answer 4

It is open because you don't know what p is therefore you cannot tell if it is true or false.

Answer 5

If I say, p=0, then it is false.

Answer 6

If I say p = 1, then it is true.

Answer 7

But as it stands, you cannot tell because it is open.

Answer 8

Okay, I get it kinda. When I collect like terms, would I add them or subtract them in this equation? And why?

Answer 9

You don't do anything with it except to answer the question by choosing A

Answer 10

Whether it is true or false depends on the value of p which you do not know.

Answer 11

Maybe p is the number of days until Christmas in which case the sentence is false.

Answer 12

Oh alright, I get it now. Thank you very much.

Answer 13

Maybe p is the age in months of a child born on September 5, 2013. Then the sentence is true.

Answer 18

It's a conceptual question. Mert explained it quite well.

Answer 19

I know, but without an effort from the student trying to figure out what those words meant first? :(
we're taking away the incentive of trying to figure out first
