Final answer:
To find the value of x that makes the ratios 2:x and 12:18 equivalent, we can set up a proportion and solve for x. The value of x is 3.
Step-by-step explanation:
To find the value of x, we can set up a proportion using the given ratios. The first ratio is 2:x and the second ratio is 12:18. Setting up the proportion, we get:
2/x = 12/18
To solve for x, we can cross-multiply: 2 * 18 = 12 * x
36 = 12 * x
Dividing both sides by 12, we find x = 3.
