Question

i cant get these two questions please help

|1+p/2| = 3
4,8
-4,-8
-4,8
4,-8



|3r - 12| = 0
-4,4
0,4
0,-4
4

Answer 1

The first equation means that 1+p/2 is exactly 3 units from 0 on the number line.
That means it could be either 3 or -3. So write and solve the two equations: 1+p/2 = 3 or 1+p/2 = -3

Answer 2

that didnt help but thanks i guess

Answer 3

What. You don't know how to solve the two equations?

Answer 4

if I did I wouldnt have came here.

Answer 5

To solve 1+p/2 = 3 first subtract 1 from both sides and get p/2=2. Now multiply both sides by 2 and get p = 4.

Answer 6

To solve 1+p/2 = -3 first subtract 1 from both sides and get p/2 = -4. Now multiply both sides by 2 and get p = -8

Answer 7

|3r-12|=0 can only be true if 3r-12 = 0
Add 12 to both sides and get 3r = 12. Now divide both sides by 3 and get r = 4
