j is the answer because 1/8 of the houses is 5 2/5 of 40 is 16 and 16 +5 =21 40-21 =19

Answer:

J. 19 houses

Step-by-step explanation:

Since there is a total of 40 houses in the neighborhood.

So, Number of houses Company X provide electricity is: [tex]\dfrac{1}{8}\times40 = 5[/tex]

and, Number of houses Company X provide electricity is: [tex]\dfrac{2}{5}\times40 = 16[/tex]

Hence total number of houses Company Z provide electricity is: 40 - (5 + 16) = 40 - 21 = 19

⇒ Total number of houses Company Z provide electricity = 19

Thus, Option (J) is correct.
