1) The digit in the tens place of a two-digit number is three times that in the onesplace. If the digits are reversed, the new number will be 36 less than the originalnumber. Find the number.2) The numerator of a rational number is less than its denominator by 3. If thenumerator becomes three times and the denominator is increased by 20, thenew number becomes . Find the original number. |
|
Answer» Step-by-step EXPLANATION: let the number be 10x + y so ACCORDING to condition 1 x=3y ___(1) if digit are reversed then the number formed 10y +x It is given that difference is 36 10x +y - (10y + x ) = 36 10x + y - 10y - x = 36 9x - 9y = 36 9(x - y) = 36 x - y = 4 3y - y = 4 ( from (1)) 2y = 4 y = 2 then from (1) x = 3y x = 3 ×2 x = 6 so the ORIGINAL number was 10x + y = 62 reverse it 26 and 62 - 26 = 36 Hence it is verified also |

First answer to get brwinspeech about health is wealth |
|
Answer» Step-by-step explanation: Health is wealth is a famous PROVERB which means that health is EVERYTHING and its importance is more than the wealth. If one maintains his/her health, he gets everything in the life very easily. We have PROVIDED below various speech on health is wealth under different words limit for the school children. They can select any health is wealth speech given below: Speech on Health is Wealth Health is Wealth Speech 1 Good MORNING to my respected teachers and all my fellow classmates. As we have gathered here to celebrate this auspicious occasion, I would like to speech over health is wealth. As we all know about the common saying that health is wealth but I do not think that we follow this proverb in our daily life to get maintained. Everyone of us knows well that a good health lead to the good way however no one of us take care of the health. If we are not living in discipline and following nature’s rule, we can never become HEALTHY in the life and never reach to the success. |

If x= 1/(7+4√3) and y=1/(7-4√3 )find 5x² -7xy -5y² |
|
Answer» Answer: -976.945 Step-by-step explanation: If x=1/(7+4√3) ==> x = 7-4√3 (by factorization) SIMILARLY for y, it is y = 7+4√3 And XY = (7+4√3)*(7-4√3) = (7)^2 - (4√3)^2 = 49 - 48 = 1 ==> x^2 - y^2 = (7-4√3)^2 - (7+4√3)^2 = -4*(7)*(4√3) = (-193.989) or (-112√3) Now, 5*(x^2 - y^2) - 7*(xy) = 5*(-193.989) - 7*(1) = -976.945 approx. |
