Number of times pencils are more than rubbers = 7 ÷ 2 = 3.5 times
Answer: 3.5 times
Y2-y1 / x2-x1
-1-4 / 2-(-3)
-5/5
-1
So the answer is A
Answer:
Step-by-step explanation:
If two variables are directly proportional, it means that an increase in the value of one variable would cause a corresponding increase in the other variable. Also, a decrease in the value of one variable would cause a corresponding decrease in the other variable.
Given that Y varies directly with X, and Y = 15 and X = 5, if we introduce a constant of proportionality, k, the expression becomes
15 = 5k
k = 15/5
k = 3
The equation would be
Y = 3X
Therefore, when X = 9, the value of Y would be
Y = 3 × 9
Y = 27
To solve this problem we can use proportion, but first its nice to transform our fraction into improper fraction, so
and
Now we can make proportion
