When 47 is added to a number the result is 37 less than 7 times the number

Answers

Answer 1

Answer: 47 is added to a number ⇒ 47 + x
37 less than 7 times the number ⇒ 7x - 37

47 + x = 7x - 37

x - 7x = -37 - 47
- 6x = -84
x = -84 / -6
x = 14

The value of the unknown number is 14.

47 + x = 7x - 37
47 + 14 = 7(14) - 37
61 = 98 - 37
61 = 61

James is setting up a fish tank. He is buying a breed of goldfish that typically grows to be 12 inches long . It's recommended that there be 1 gallon of water for every inch of fish length in the tank . What is the recommended ratio of gallons of water per fully grown gold fish in tank ?

Answers

12:12 is the ratio because each fish can grow up to be 12 inches long so 12 gallons would be in the tank per fish.

Final answer:

The recommended ratio of gallons of water per fully grown goldfish in a tank is 12:1. This means for every goldfish that grows up to 12 inches, there should be 12 gallons of water in the tank.

Explanation:

James is setting up a fish tank and planning to house a breed of goldfish that typically grows to be 12 inches long. Considering the recommendation, there should be 1 gallon of water for every inch of fish length in the tank. Therefore, for a fully grown goldfish of 12 inches, James will require 12 gallons of water per goldfish - this is the recommended ratio of gallons of water per fully grown goldfish in the tank.
