HELP WITH MATH TEST

Variable p is 2 less than variable d. Variable p is also 1 more than variable d. Which pair of equations best models the relationship between p and d? (5 points)

a
p = d + 2
p = d − 1

b
p = d − 2
p = d + 1

c
d = 2p
d = 2p − 1

d
d = 2p
d = 2p + 1

Answer 1

b)

p = d − 2

p = d + 1

Explanation:

From the above question:

Interpreting the statement above to form algebraic expressions, we have:

Variable p is 2 less than variable d.

Less than means to subtract in this context

p = d - 2

Variable p is also 1 more than variable d

More than means to add in this context

p = d + 1

Therefore, the pair of equations tha best models the relationship between p and d is Option b :

p = d − 2

p = d + 1
