bellla is three times as old as edward,jacob is one-half the age of alice. alice is 4 year older than edward bella is 24 years old . who is the youngest
b =3e j=a/2 a = e+4 b=24 just transcribe the words into eqns. start plugging in, find e from b=3e and b=24. when you have e, find a with a=e+4. continue until you have all of them.
i still dont get it
a= Alica b = Bella e = Edward j= Jacob whenever you have this type of word problems, show relations with variables and equations...it makes it easier
when they say someone (let's call them x) is 3times as old as y, the eqn would be : x=3y
so like how do i find out the awnser
make mathematical equations (relationships between the variables) from the story they give you. Then, start plugging in your knowns
do you understand the eqns?
24=3xE that means E = 8 A = E+4 that means A = 12 J = A/2 that means J = 6 Answer: Bella - 24 Edward - 8 Alice - 12 Jacob - 6
in other words, jacob is the youngest.
thank you i get it
no problem :D
