Question

Evaluate the expression for the given value of the variable 39 +1/8n=? n= -1/2

Answer 1

Answer:

38  15/16

Step-by-step explanation:

39 + 1/8n

Since the n = -1/2, replace the 'n' in the original equation with that number

39 + 1/8 (-1/2)

Multiply numerator-to-numerator and denominator-to-denominator

1/8 times -1/2 equals -1/16

(Because a positive times a negative equals a negative)

Now your complete equation is:

39 + -1/16

Add those numbers together to get 38  15/16
