a. if ( p ) represents the number of miles pietra walked, which equation represents the total number of miles ( t ) the two girls walked?

a) ( t = p^2 + 7 )

b) ( t = p + (p + 7) )

c) ( t = p + (p - 7) )

d) ( t = p - (p + 7) )

part b

b. if pietra walked 9 miles during the week, how many miles did deanna walk?
______ mi

Explanation:

Step1: Define Deanna's miles

Deanna walked $p + 7$ miles.

Step2: Calculate total miles

Total $T = \text{Pietra's miles} + \text{Deanna's miles} = p + (p + 7)$

Step3: Solve for Deanna's miles

Substitute $p=9$: $9 + 7 = 16$

Answer:

B) $T = p + (p + 7)$
16 mi
