the sum of two numbers is 63. one ninth of the first number plus one sixth of the second number is 21. find the numbers
PSYCHO15rus [73]

Answer: x= -189, y =252

Step-by-step explanation:

Let the first number be x and second number be y

so

x + y = 63

x = 63-y

now

1/9 of x + 1/6 of y = 21

x/9 + y/6 = 21

substituting x's value from equation i

(63-y)/9 + y/6 = 21

(378-6y+9y)/54 = 21

378+3y = 1134

3y = 1134-378

so, 3y = 756

so, y = 756/3

so, y = 252

now

x = 63-252

so, x = -189

Gnom [1K]
Let's assume that the total daily allowance of fat is given, otherwise let's just assign a variable for it.

We can make the formula based on the given data.

Percentage = Total daily allowance of fat given / total intake of fat per day * 100

So, the equation Percentage = Total / 48 * 100 will be used in order to get the percentage of the total amount.
