Question

Variable c is 5 more than variable a. Variable c is also 3 less than variable a. Which pair of equations best models the relationship between c and a?

c = a − 5
c = a + 3
a = c + 5
a = 3c − 3
a = c − 5
a = 3c + 3
c = a + 5
c = a − 3

Answer 1

c = 5 + a @ c = a + 5
c = a - 3

hope this would help u

Answer 2

Last pair of equations.

Explanation:

variable c is 5 more than variable a can be represented with c = 5+a and variable c is 3 less than variable a can be represented with c = a-3. So, the pair of equations are:

c = 5+a

c = a - 3.
