The sum of 2 digits number and the number forward by interchange the digits is 132 |
| Answer» Let the two digit no. be 10x + yand the no. when reversed be 10y + xaccording to the question :10x + y + 10y + x = 13211x + 11y = 132taking 11 common11(x + y ) = 132x + y = 12 ----------- 1)lets do the second partNow,10x + y + 12 = 5(x + y)10x + y + 12 = 5x + 5y5x + 12 = 4y4y - 5x = 12 ------ 2)substituting y = 12 - x in equation 2)4( 12 - x ) - 5x = 1248 - 4x - 5x = 1248 - 12 = 9x36 = 9xx = 4x + y = 124 + y = 12y = 8so the no. is 48 | |

What is linear equation in two variable |
|
Answer» An\xa0equation\xa0that can be put in the form ax + by + c = 0, where a, b and c are real numbers and a, b not equal to zero is called a\xa0linear equation in two variables\xa0namely x and y. The solution for such an\xa0equation\xa0is a pair of\xa0values, one for x and one for y which further makes the\xa0two\xa0sides of an\xa0equation\xa0equal. An equation is said to be linear equation in two variables if it is written in the form of ax+by+c=0, where a,b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.For example, 10x+4y = 3 and -x+5y = 2 are linear equations in two variables. |

root 5 is an irrational number . prove that |
|
Answer» I know "√5 is an “irrational number”.Given:√5To prove:√5 is a rational numberSolution:Let us consider that √5 is a “rational number”.We were told that the rational numbers will be in the “form” of\xa0form Where “p, q” are integers.So,\xa0we know that \'p\' is a “rational number”. So 5 \\times q should be normal as it is equal to pBut it did not happens with √5 because it is “not an integer”Therefore, p ≠ √5qThis denies that √5 is an “irrational number”So, our consideration is false and √5 is an “irrational number”."
