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 =
Answer:
answer: 2:2
Step-by-step explanation:
1:2+2:2 to get 3:4
Answer:
To figure out the change, we subtract the original temperature by the following after temperature.
18°F - original
-9°F - subsequent time after original
So we set up the equation;
18°F - (-9°F)
(Two negatives combine to form a positive)
18°F + 9°F
= <u>27°F</u> was the change in temperature.
