zhannawk [14.2K]

Answer:

C. 4 miles; it represents the original distance of the bee from its hive

Step-by-step explanation:

We are given,

The graph showing the distance between a bee hive for a certain amount of time.

Now, from the graph, we see that,

When the time is 0 mins, then the distance from the bee hive is 4 miles.

Thus, the initial value of the graph is 4 miles and it represents the original distance of the bee hive from the hive.

So, option C is correct.

Sushil is 6 years older than Brian. Caroline is 5 years younger than Brian. If the total of their ages is 64, how old is the you

Nadusha1986 [10]

Answer:

16 years old

Step-by-step explanation:

Let's use the letters s, b, and c for Sushil, Brian, and Caroline's ages. Sushil is the oldest, followed by Brian, and then Caroline, the youngest. From the problem description, we can set up three equations:

s = b + 6 (Sushil is 6 years older than Brian)

c = b - 5 (Caroline is 5 years younger than Brian)

s + b + c = 64 (The total of their ages is 64)

Since s and c are already in terms of b, we can substitute them into the last equation and solve to find Brian's age:

(b + 6) + b + (b - 5) = 64

3b + 1 = 64

3b = 63

b = 21

Now that we know Brian's age, we can simply subtract 5 to find Caroline's:

c = b - 5 = 21 - 5 = 16 years old.
