Final answer:
To solve the given proportion x/13 = 17/7, cross multiply and solve for x by dividing both sides of the equation.
Step-by-step explanation:
To solve the proportion x/13 = 17/7, you can cross multiply. Multiply 13 by 17 to get 221, and multiply x by 7 to get 7x. So the equation becomes 221 = 7x. To solve for x, divide both sides of the equation by 7. 221/7 = x. Simplifying, x = 31.57 (rounded to two decimal places). Therefore, the value of x is approximately 31.57.
