There should be no problem in finding the value of the unknown variable "b" in the equation given in the question.The equation is solvable for finding the value of "b" because it is the only unknown variable in the single equation that is given in the question.
45 = 3b + 69
Let us reverse both sides of the equation first. then, we get
3b + 69 = 45
3b = 45 - 69
3b = - 24
b = - (24/3)
= - 8
So from the above deduction, we can easily conclude that the value of b in the given equation is -8.
Perimeter = 2L + 2W (where L = length and W = width)
And we are given that L = 3W
So substituting for L, we have the equation:-
2(3W) + 2W = 64
6W + 2W = 64
8W = 64
W = 8 meters
So the length = 3*8 = 24 meters
Answer:- Length = 24 m and Width = 8 m.
Ordered pairs that work for this direct variation are (4, 3), (8, 6) and (12, 9).
In order to find these, we must first find the value of the direct variation coefficient. We can do that using the base equation y = kx and then by plugging in to find k.
y = kx
12 = k(16)
3/4 = k
Now that we have k, we can model the equation as y = 3/4x. We can also find any number of ordered pairs by using the x value and finding the y value. All of the above answers work.
The correct answer is x because u have to look on the x axis
