Step-by-step explanation:

The ratio of marked fish to caught fish is 4:10, we need to solve for x in 20:x, since 4 * 5 = 20, 10 * 5 = x so x = 50 fish.

Answer:

Step-by-step explanation:

65 ÷ b + 8 x 4 = 20

Putting value of b = 5 in the equation

65 ÷ 5 + 8 x 4 = 20

13 + 8 x 4 = 20

13 + 32 = 20

45 = 20

Bringing like terms on one side

45 - 20 = 25
