To find the value of x in each of these proportions, we can set up proportions for each equation:
5/7 = 15/x
Cross multiply to solve for x:
5x = 105x = 105 / 5x = 21
Therefore, x = 21 for the first proportion.
Continuing with the next proportion:
15/x = x/28
15 * 28 = x^2x^2 = 420x = √420x ≈ 20.49
Therefore, x ≈ 20.49 for the second proportion.
Moving on to the third proportion:
x/28 = 30/x
x x = 28 30x^2 = 840x = √840x ≈ 28.98
Therefore, x ≈ 28.98 for the third proportion.
Lastly, for the fourth proportion:
30/x = x/77
30 * 77 = x^2x^2 = 2310x = √2310x ≈ 48.02
Therefore, x ≈ 48.02 for the fourth proportion.

Continuing with the next proportion:
15/x = x/28
Cross multiply to solve for x:
15 * 28 = x^2
x^2 = 420
x = √420
x ≈ 20.49
Therefore, x ≈ 20.49 for the second proportion.

Cross multiply to solve for x:
x x = 28 30
x^2 = 840
x = √840
x ≈ 28.98
Therefore, x ≈ 28.98 for the third proportion.
Lastly, for the fourth proportion:
30/x = x/77
Cross multiply to solve for x:
30 * 77 = x^2
x^2 = 2310
x = √2310
x ≈ 48.02
Therefore, x ≈ 48.02 for the fourth proportion.
