One of the elephants in the zoo is on a special diet. Every day, the elephant eats the same amount of carrots that the rabbit eats in 1 year (365 days). The rabbit eats the same amount of carrots every day. Together, in one day, the elephant and rabbit eat 122 kilograms of carrots. How many kilograms of carrots does the rabbit eat in one day?

1/3 kg.

Step-by-step explanation:

The ratio of the amount of carrots the elephant eats to the amount of carrots the rabbit eats in the same length of time is 365:1.

So if the total they both eat is 122 kg in one day, the rabbit eats 122 * 1/ 366

= 1/3 of a kg,

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
