A varies directly with b → a = kb where k is the constant of variation (i.e. slope)
-2 = k × 3 ← substitute values into the formula above
-2/3 = k ← result of dividing both sides by 3
Answer: k =
-2 = k × 3 ← substitute values into the formula above
-2/3 = k ← result of dividing both sides by 3
Answer: k =
Answer:
110
Step-by-step explanation:
Let the three numbers be 100, 110 and 120
100 + 110 + 120 = 330
Total numbers = 3
Answer:
Ms. Thomas was driving at constant rate of 52 miles/hour.
Step-by-step explanation:
Given:
Total time to travel (t) = 45 minutes
Distance drove (d) = 39 miles
we need to find the constant rate in miles per hour at which she was driving.
Solution:
Now we know that;
We need to find constant rate at miles per hour;
But time is given in minutes.
So we will convert minutes into hour by dividing by 60 we get;
time
Now we know that;
Distance is equal to rate times time.
framing in equation form we get;
distance
Or
rate
Hence Ms. Thomas was driving at constant rate of 52 miles/hour.
