Question

PLEASE HELP QUICKLY!

Select TWO equations that have the same value of p when solved.
1) p+5=6
2) 2(p+2)=3
3) 0.2p−8=8.2p
4) 8p−12=−4
5) p+4=2p

Answer 1

1,5

Explanation:

Equations 1 and 5 have the same value of p when solved.

p+5=6 can be solved as:

p = 6 - 5 = 1

p+4=2p can be solved as:

p = 4

Answer 2

Answer:
1 and 4 solve to p = 1

Step by step solved:

To find which equations have the same value of p when solved, we need to solve each equation for p and compare the solutions.

1) p+5=6
Subtracting 5 from both sides:
p+5-5=6-5
p = 1

2) 2(p+2)=3
Distributing the 2:
2p + 4 = 3
Subtracting 4 from both sides:
2p = -1
Dividing both sides by 2:
p = -1/2

3) 0.2p−8=8.2p
Subtracting 0.2p from both sides:
-7.8p - 8 = 0
Adding 8 to both sides:
-7.8p = 8
Dividing both sides by -7.8:
p = -1.0256

4) 8p−12=−4
Adding 12 to both sides:
8p = 8
Dividing both sides by 8:
p = 1

5) p+4=2p
Subtracting p from both sides:
4 = p
So the equations that have the same value of p when solved are:

1) p+5=6 and 4) 8p−12=−4, both solve to p = 1
