Directly proportional, both increase/decrease, Multiple k(constant you needed to solve for)..
Inversely --one increases as the other decreases, increase the denominator & fraction gets smaller.... So
Problem:
Dirextly to X (× by X)
Inversely to Y, (÷ by Y)
Z= k X/Y
Solve, working backwards: Z =5 becomes
5 = k (X) ÷ (Y). And
X=15 and Y =9 becomes
5= k(15)/(9). Undo ÷9, ×9 both sides
45= k(15). Now undo ×15 by ÷15 both sides
45/15 = 3. So k=3, (also called your constant of variation)....and your Equation/Proportion becomes...
Z = 3X/Y
Use the new #s.... X=23, Y=14
Z= 3×23÷14 = 69/14. If they want spirochete answer divide and round to corresponding # if decimals
Option C: Clifton takes 6 minutes and 30 seconds to run one mile.
Explanation:
Given that Clifton ran 6 miles in 39 minutes.
We need to determine the time it takes for Clifton to run one mile.
To determine the time that it takes for Clifton to run one mile, we shall divide 39 minutes by 6 miles.
Thus, we have,
-------(1)
To convert 0.5 minutes to seconds, let us multiply the value by 60.
Thus, we have,
Thus, substituting in equation (1), we have,
Therefore, it takes 6 minutes and 30 seconds for Clifton to run one mile.
Hence, Option C is the correct answer.
Answer:
positive to zero because its above the zero
