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

Last pair of equations.

Step-by-step 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.

to rewrite a literal equation you may need to divide by a number, or by a variable.

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
