If one kilogram is 2.2 pounds how many kilograms would it make for 11 pounds
Mila [183]

Answer:

5 kg

Step-by-step explanation:

To solve this problem, we can use the rule of three.

In fact, we know that:

- 1 kilogram is equivalent to 2.2 pounds

- The ratio between the mass in kilograms and in pounds is constant for every value of the mass

- Therefore, the mass in kilograms corresponding to 11 pounds can be found by writing the following equation:

\frac{1 kg}{2.2 p}=\frac{x}{11 p}

Where

x is the mass in kilograms corresponding to 11 pounds.

Solving the equation for x, we find:

x=\frac{(11p)(1kg)}{2.2p}=5 kg

Marianna [84]

Answer: No, the equation is not accurate.

Step-by-step explanation: The proper equation is 4x + 40 = 129. This is because 16 is nowhere in the scenario, and the term before x is months, so the correct term would be 4x.
