A woman is 3 times as old as her son. 8years ago the product of their age was 112. Find their present age. Anyone to explain hw to solve dis qustn. Thank Solution Mother age =x son age = y x =3y 8 YEAR AGO, YOU WILL HAVE TO SUBTRACT 8 FROM X AND 8 FROM Y, MULTIPLY BOTH TOGETHER [x -8][y-8]=112 SUBSTITUTE X=3Y INTO THE PRODUCT [3y-8](y-=112 3y^2-24y-8y+64=112 3y^2-32y - 48=0 [y-12][3y+4]=0 y=12, ignore the fraction so x= 3(12) =36 YOU CAN LEARN AT WWW.MATHSVILLAGE.ORG |

Re: Mathematics/further Maths by simeonabio(m): 3:43pm On Aug 15, 2013 |
Friend..... try to finish up the work, use quadratic formula (almighty formula) a=3 b =-32 c= -48 If you obtain fraction in your answer, then there is mistake in the question you posted because ages are whole number As for the site, it is going through. Possibly you network is slow. try it again www.mathsvillage.org |

simeonabio: Friend..... try to finish up the work, use quadratic formula (almighty formula)X=72 OR -8 |
Re: Mathematics/further Maths by Ujawissy: 5:26pm On Aug 15, 2013 |
Fynestboi: PLS SHOW D FULL WORKING THANKSok let start:let mother's age=m son age =s m=3s(she is 3 times as old as the son)...egn 1 [m-8][s-8]=122. . egn 2 subst. egn 1 into egn 2.u |
Re: Mathematics/further Maths by Ujawissy: 5:44pm On Aug 15, 2013 |
cont. . after subst 3s for m in egn 2 and expand. u will have:3s(sguare) -32s -48(after solving u gonna have:s=12,1/3 but ur ans can't be in fraction so u go with 12) NOTE:dat is for the son. mother we said m=3s =3[12=36 s=12, m=36 |

Found a similar questn A woman is 4 times older than her child. 5years ago the product of their age was 175. Find their present age. Here s d ansa i got...[10, 40] to mai ogas am i correct?? |
Re: Mathematics/further Maths by BRAINEE123: 5:23am On Aug 16, 2013 |
Fynestboi: Found a similar questn use the method proferred so far to get the ans.If truely you are learning that branch of quadratic word problems,then you should be able to solve similar problems by yourself without our attention. Open a new topic like cordinate geometry,calculus,trigonometry, matrix et |
Re: Mathematics/further Maths by Tosinisaac(m): 6:27am On Aug 16, 2013 |
for math guru.. solve this complex number (2+3¡)^2¡ |
Re: Mathematics/further Maths by BRAINEE123: 11:41am On Aug 16, 2013 |
Tosinisaac: for math guru.. (2+3i)^2*i [ (2+3i)(2+3i) ]^i [ 4+12i+9i^2)^i where i^2= -1 (4+12i-9)^i (-5+12i)^i or (-5+12i)^sq root of -1 |
