Answer»

Step-by-step EXPLANATION:

Answer

NUMBER of votes received by three candidates =687905+495086+93756=1276747

Number of INVALID votes =13849

Number of persons who did not vote =25467

∴ Total number of registered votes =1276747+13849+25467

We are also given with the answer obtained while solving those two rational numbers. But, we are not given with the second number that the FIRST number should be added with.

6. The sum of two rational numbers is -6/19.If one of them is 8/57,find the other.it's urgent plz answer

Answer»

★ How to do :-

Here, we are given with one of the rational number that should be added to the other number. We are also given with the answer obtained while solving those two rational numbers. But, we are not given with the second number that the FIRST number should be added with. We are ASKED to find the same. Here, we use the concept of shifting the numbers from one hand side to the other which changes it's sign. We can find the VALUE of other fraction. So, LET's solve!!

$\:$

➤ Solution :-

${\tt \leadsto \dfrac{8}{57} + x = \dfrac{(-6)}{19}}$

Shift the fraction on LHS and RHS, changing it's sign.

${\tt \leadsto x = \dfrac{(-6)}{19} - \dfrac{8}{57}}$

LCM of 19 and 57 is 57.

${\tt \leadsto x = \dfrac{(-6) \times 3}{19 \times 3} - \dfrac{8}{57}}$

Multiply the numerator and denominator of first fraction

${\tt \leadsto x = \dfrac{(-18)}{57} - \dfrac{8}{57}}$

Now, write both numerators with a common denominator.

${\tt \leadsto x = \dfrac{(-18) - 8}{57}}$

Subtract bith numerators to get the answer.

${\tt \leadsto x = \dfrac{(-26)}{57}}$

$\:$

${\red{\underline{\boxed{\bf So, \: the \: other \: number \: is \: \: \dfrac{(-26)}{57}}}}}$

━━━━━━━━━━━━━━━━━━━━━

Verification :-

${\tt \leadsto \dfrac{8}{57} + x = \dfrac{(-6)}{19}}$

Substitute the value of x.

${\tt \leadsto \dfrac{8}{57} + \dfrac{(-26)}{57} = \dfrac{(-6)}{19}}$

Write both numerators with a common denominator.

${\tt \leadsto \dfrac{8 + (-26)}{57} = \dfrac{(-6)}{19}}$

Write the second number in numerator with only one sign.

${\tt \leadsto \dfrac{8 - 26}{57} = \dfrac{(-6)}{19}}$

Subtract the values on numerator on LHS.

${\tt \leadsto \dfrac{(-18)}{57} = \dfrac{(-6)}{19}}$

Write the obtained answer in lowest FORM by cancellation method.

${\tt \leadsto \dfrac{(-6)}{19} = \dfrac{(-6)}{19}}$

So,

${\sf \leadsto LHS = RHS}$

$\:$

Hence verified !!

23.	51(2) The solution of the equation 3x –2.=+ x is ...2
Answer» ★ How to do :- Here, we are given with an EQUATION in which we have two variables and two constants and the equal sign. We are asked to find the value of the variable x. We can find the value of this variable easily by using other CONCEPTS. The concept used here is the transposition METHOD. This method helps us to find the value of x. In this method, we shift the variables on LHS and all the constants on RHS. By this, we can simplify the constants and then, find the value of the variable. We can also VERIFY our answer by verification method. So, LET's solve!! $\:$ ➤ Solution :- ${\tt \leadsto 3x - \dfrac{1}{2} = \dfrac{5}{2} + x}$ Shift the variable on RHS to LHS and constant on LHS to RHS. ${\tt \leadsto 3x - x = \dfrac{5}{2} + \dfrac{1}{2}}$ Subtract the values on LHS and add the values on RHS. ${\tt \leadsto 2x = \dfrac{5 + 1}{2}}$ Add the numerators on RHS. ${\tt \leadsto 2x = \dfrac{6}{2}}$ Simplify the fraction on RHS. ${\tt \leadsto 2x = 3}$ Shift the number 2 from LHS to RHS. ${\tt \leadsto x = \dfrac{3}{2} = 1.5}$ $\:$ ${\red{\underline{\boxed{\bf So, \: the \: value \: of \: x \: is \: \: \dfrac{3}{2} \: or \: 1.5}}}}$ ━━━━━━━━━━━━━━━━━━━━━━ Verification :- ${\tt \leadsto 3x - \dfrac{1}{2} = \dfrac{5}{2} + x}$ Substitute the value of x. ${\tt \leadsto 3 \bigg( \dfrac{3}{2} \bigg) - \dfrac{1}{2} = \dfrac{5}{2} + \dfrac{3}{2}}$ Write the numerators and denominators in a common fraction. ${\tt \leadsto \dfrac{3 \times 3}{2 \times 1} - \dfrac{1}{2} = \dfrac{5 + 3}{2}}$ Multiply the fractions on LHS and add the fractions on RHS. ${\tt \leadsto \dfrac{9}{2} - \dfrac{1}{2} = \dfrac{8}{2}}$ Write both numerators with a common denominator on LHS. ${\tt \leadsto \dfrac{9 - 1}{2} = \dfrac{8}{2}}$ Write the obtaining fraction. ${\tt \leadsto \dfrac{8}{2} = \dfrac{8}{2}}$ So, ${\sf \leadsto LHS = RHS}$ $\:$ Hence verified !!
