Answer:
i. 10 units (Carol's house is 10 units on the right from Ann's house)
ii. -10 units (Carol's house is 10 units on the left to Ann's house)
Step-by-step explanation:
A number line is a system that can be used to express the location of directed number on a straight line. It has an origin which is taken to be zero (0).
In the given question, Ann's house is located at 0 of the number line. Let 1 block be represented by 1 unit on the number line.
Thus, Ben lives 8 blocks from Ann implies that Ben's house is at 8 units from Ann's house.
Given that Carol's house is 2 blocks from Ben implies that Carol's house is 2 units from Ben.
So that,
The possible locations of Carol's house depends on its position with respect to Ann's house.
i. Carol's house = 8 + 2
= 10 units
This implies that Carol's house is 10 units on the right from Ann's house.
ii. Carol's house = - 8 - 2
= -10 units
This implies that Carol's house is 10 units on the left to Ann's house.

Answer:
.4 is the answer
Step-by-step explanation:
This is a right triangle problem. We have one leg as .5 in length and the other leg as 1.2 in length. The "straight" way to your grandma's house is the hypotenuse. We need to find that length which will give us the distance straight from your house to their house if you didn't have to go out of your way to avoid the water. The hypotenuse is found with Pythagorean's Theorem. It will be filled in and solved as follows:
and c = 1.3
That's the straight distance. You had to go out of your way to the tune of .5+1.2 which is 1.7 miles. You figure out how much shorter it is taking the straight path by subtracting 1.7 - 1.3 which is .4
