Answer:
The Correct option is C ) 25
Therefore the value of x is 25 when y =40.
Step-by-step explanation:
Given:
Variable 'y' is directly proportional to the variable 'x'.
......Direct Variation
Where,
k = Constant of proportionality
To Find:
value of x = ? when y = 40
Solution:
First we need to find Constant of proportionality
When x = 20 and y = 32
Substituting the values we get
Now when k =1.6 , y = 40 then x will be
Therefore the value of x is 25 when y =40.
The answer would probably be 36
X>10/-2
x> -5
so the answer is x>-5
It’s the third one, P > 38
Because if x > 9 the 16+13+x= 38 or more.
So P (16+13+x) is greater than 38.
Hope this helps!
