The distance between mike’s house and the grocery store is 4/5 of a mile. mike has walked 1/2 of a mile from his house to the grocery store. how much farther does he needs to walk to reach the grocery store? a. 13/10 miles b. 3/4 of a mile c. 3/10 of a mile d. 2/5 of a mile

C. 3/10 of a mile

Step-by-step explanation:

1. You know that:

- The distance between Mike’s house and the grocery store is 4/5 of a mile.

- He has walked 1/2 of a mile from his house to the grocery store.

2. Keeping this on mind, you can calculate the rest of the distance he need to walk (which you can call d) to reach the grocery store by subtracting 4/5 of a mile and 1/2 of a mile, as you can see below:

3. The answer is the option C.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
