Question

P=a+b+c, p=29, a=6, b=11

Answer 1

The answer I got was 191

Explanation:

P=29

A=6

B=11

29x6+11+c

C=1 because it is a variable

29x6=174

174+6=180

180+11=191

The answer is 191.

Answer 2

Explanation:

1) Substitute 29 for p in the equation because p=29:

29=a+b+c

2) Substitute 6 for a because a=6:

29= 6+b+c

3) Substitute 11 for b because b=11:

29=6+11+c

4) Solve for c because it is the only variable left.

29=6+11+c

29=17+c

29-17=c

12=c

Answer: c=12
