X= 30/r is the answer because if you divide both sides by r you are left with x=30/r because you cant divide 30 by r

Answer:
Option (C)
Step-by-step explanation:
x and y are two rational numbers.
Two inequalities which define these numbers are,
x + y < 5 ------(1)
3 < x < 5 -------(2)
In this question we will substitute the values of y given in the options in the inequality (1) to get the value of x. If the value of x satisfies the inequality (2), it will be the answer.
Option (A). y =
From inequality (1),
x <
x < 2.33
But 3 < x < 5, therefore, y = is not the answer.
Option (B). y = 2
x + 2 < 5
x < 3
But x is greater than 3. Therefore, Option (B) will not be the answer.
Option (C). y = 0
x + 0 < 5
x < 5
Inequality (2) states the same thing.
Therefore, Option (C) will be the answer.
Option (D). y = 3
x + 3 < 5
x < 5 - 3
x < 2
But x > 3, therefore, Option (D) will not be the answer.
