9p+8=10p+7
8=19p+7
15=19p
Then divide 15 and 19 to get p. So the equation isn't open or false because you can solve it.

how do you determine if the answer to a problem is negative or positive in division multiplication addition and subtraction

erica [24]

In multiplication, a negative times a positive has a negative answer. if both are positive or both are negative, the answer is positive.
5 * -5 = -25
-5* -5 = 25

in divisions say you have
-5/5 = -1
-5/-5= 1
5/-5= -1

in addition and subtraction, subtracting a negative means to add the two numbers. adding a negative means to subtract the second number.

5+ (-5) = 0
5- (-5) = 10

How do you do this and what are the answers

I can answer 1 to 4...
The area of a circle can be found by $\pi r^{2}$ . Reminder: $\pi = 3.14$ (usually used when finding out the area of a circle)

1. $4^{2} = 16$
$\pi *16$ or $3.14 * 16 = 50.24$
$50.24/4=12.56$

2. $6^{2} = 36$
$\pi *36$ or $3.14 * 36 = 113.04$
$113.04/10=11.304$

(Not really sure if this is correct) 3. $2^{2}=4$
$\pi *4$ or $3.14 * 4$
$12.56/2.66666667=11.70999999$

4. $6^{2}=36$
$\pi *36= 113.04$
$113.04/6=18.84$
