11x + 15y +23 = 0 7x + 2y - 20 = 0 |
| Answer» 11x+15y+23=011x+15y= -23. (equ.1st)7x-2y-20=07x-2y=20. (equ.2nd)11x+15y=-237x-2y = 20multiply by (2) in equ. 1st &( 15) in equ. 2nd we get.22x+30y= -46. ( equ. 3rd)105x-30y= 300. (equ. 4th)_____________127x=254X=254/127X = 2.put the value of X in equ. 2nd7x-2y=207(2)-2y =20. (X=2)14-2y =20-2y=20-14-2y= 6y= 6/-2y=-3.Your answer => X = 2 , Y= -3. | |

How many numbers divisible by 6 between 100 to 1000 |
|
Answer» Take multiples of 6 after 100 ex = 102,108,114.........and last multiple before 1000 ex=996. Now a=102,d=6 and an=996.Now use formula an=a+(n-1)d.By this formula you can find n and this is your required answer.In this way you can solve your question. Take It as Ap: 102,108,114.......996There is 102 is first no. Which is divisible by 6 & 996 os last no. Which is divisible by 6 b/w 100 to 1000.Now, a=102,an=996,d=6,Now you can use the formulaAn=a+(n+1)d |

Find the HCF of 36,96,120 |
|
Answer» 36=2×2×3×396=2×2×2×2×2×3120=2×2×2×3×5Therefore HCF(36,96,120)=2×2×3=12 By Euclid\'s division lemma on 36 and 96a=bq+r , where r is equal to or greater than 0 and smaller than bSince 96 is greater than 36Therefore a= 96 and b= 36Now, 96=36×2+24 36=24×1+12 24=12×2+0Since 12 is the last divisore therefore 12 is HCF of 36 and 96Now, we will take HCF of 12 and 120By Euclid\'s division lemmaa=bq+r, where r is equal to or greater than 0 and smaller than bSince 120 is greater than 12 Therefore a= 120 and b= 12Now, 120=12×10+0Since 12 is the last divisore therefore 12 is HCF of 12 and 120.Therefore HCF of 120,96 and 36 is 12 On applying euclid\'s division Lemma for 36 and 9696 = 36 ×2 + 24Here, Remainder = 24≠0So take new Dividend as 36 and divisor as 24.36 = 24×1 +12Here, Remainder = 12≠0So take new Dividend as 24 and divisor as 12.24 = 12×2 +0Here, the Remainder = 0 and the last divisor is 12.So, HCF of 36 and 96 is 12.On applying euclid\'s division Lemma for 12 and 120120 = 12 ×10 + 0Here Remainder = 0So , HCF of 36, 96 and 120 is 12. |
