The numerator of a rational number is greater than its denominator by 3. If the new number becomes 13/4 when the numerator is tr
GarryVolchara [31]

Answer:

Step-by-step explanation:

Let x represent the numerator and y represent the denominator.

The numerator of a rational number is greater than its denominator by 3. It means that

x = y + 3

If the new number becomes 13/4 when the numerator is tripled and the denominator is decreased by 23, it means that

3x/(y - 23) = 13/4

Cross multiplying, it becomes

3x × 4 = 13(y - 23)

12x = 13y - 299- - - - - - - - - - -1

Substituting x = y + 3 into equation 1, it becomes

12(y + 3) = 13y - 299

12y + 36 = 13y - 299

13y - 12y = 36 + 299

y = 335

x = y + 3 = 335 + 3

x = 338

The original number is 338/335

Twelve pounds less than twice janes weight is 270 pounds. What is Janes weight?
Tpy6a [65]
Janes weight = x
Twelve pounds less than twice janes weight is 270 pounds
12 less than 2x is 270 

2x -12 = 270   (add 12 to each side)
2x = 270 + 12
2x = 282   (divide 2 from each side)
x = 282/2
x = 141

The answer is 141 pounds
