The sum of three numbers is . The second number is times the third. The third number is less than the first . What are the numbers?
I think your question is not complete.. :)
oops! sorry haha here The sum of three numbers is 96 . The second number is3 times the third. The third number is 6 less than the first . What are the numbers?
let the three numbers are x,y,z from the first sentence, "The sum of three numbers is 96" how do you say this in x,y,z ?
not sure i understand what you mean by how we say this in x,y,z
let's say that the three numbers are x,y, and z. the first sentence say that "The sum of three numbers is 96" , we can write the sentence as "x+y+z = 96" it's what I mean.. :) do you understand now?
oh ok yesss sorry haha so x,y, and z would be 32 bcause 96/3 =32
wait..., we have no information that x, y, and z are equals... from the second sentence, we have " The second number is3 times the third" if y is the second number, and z is the third number, how do you write this in math? (in y and z)
correct... :) now, from the third sentence, we have " The third number is 6 less than the first " let, x be the first number and z be the third number, how do you write it in term of x and z?
okay.., x - 6 = z, so x = z + 6, do you get it so far?
now, we have three equations x+y+z = 96 3z = y x = z + 6 now, substitute (change) the value of x and y in the first equation with the second and third equation, what do you get?
yes =) however i feel like that was the easy part.. and the hard part is coming =o
