Answer 2

Answer: The value of x in the proportion x:30::7:5 is 42.

Step-by-step explanation:

The given statement, "x:30::7:5" is a proportion, which implies that the ratio of x to 30 is equal to the ratio of 7 to 5. We can write this as:

x/30 = 7/5

To find the value of x, we can cross-multiply both sides of the equation:

5x = 30 x 7

5x = 210

x = 42

Therefore, x is equal to 42.

To check if this answer is correct, we can substitute the value of x in the given proportion and verify if it is true.

x:30::7:5 can be written as x/30 = 7/5, which is the same as x/30 = 42/30. Simplifying this expression, we get:

x/30 = 7/5

x = 30 * (7/5)

x = 42

Thus, our solution is correct.

In summary, the value of x in the proportion x:30::7:5 is 42.
