if (2x3):(y+4)=k where k is a constant and x=4 when y=2 then find x when y=6
What does the : between the factor mean? (2x3) : (y+4)=k Multi[lication?
If so, substitute 4 for x and 2 for y to get
(2*43):(2+4)=k = 5*6
Then solve for x in
(2x3):(6+4)=30
If it means something else please post what it means.
It is suppose to be a ratio (:)
Ok, then solve
If so, substitute 4 for x and 2 for y to get
(2*43):(2+4)=k = 5/6
Then solve for x in
(2x3):(6+4)=5/6 or
2x3 = 5/6 * 2 = 5/3
Thankyou so much. That's all I have to ask. You were a huge help.
Plugging it in:
(83):(2+4) = 5:6
So,
(2x3):(6+4)
becomes
(2x3):(2)
2/6 = .33333
2x3 = .33333
2x = 2.66666
x = 1.33333
I'm not sure if this is what the question is asking, but if it's saying that k is a constant whose ratio is always 1:6, then x should be the above answer. I hope I helped.
