Answer:
To find the value of x in the proportion 7:x = 21:24, you can set up a proportion equation and solve for x.
The proportion can be written as:
7 / x = 21 / 24
To solve for x, cross-multiply:
7 * 24 = 21 * x
Now, calculate the products on both sides:
168 = 21x
To isolate x, divide both sides by 21:
x = 168 / 21
Now, simplify the right side:
x = 8
So, the value of x is 8.
