Answer:
V/lh = w
Step-by-step explanation:
V = lwh
To solve for w, we need to isolate w by itself.
Divide both sides by lh
V / lh = lwh/lh
V/lh = w
To solve a set of linear equations in 3 variables, you need 3 equations. As far as I can tell, you have 2 equations here, so the best you can do is write expressions for 2 of the variables in terms of the third.
If you have
x +z +5z = -3y -3
3x -y = -4
Then you can rewrite as
x = -1.5 -0.6z
y = -0.5 -1.8z
_____
You can get this by any of the usual methods of solving linear equations. Just treat the system as two equations in x and y with the z terms on the right side of the equal sign:
x +3y = -3 -6z
3x -y = -4
3x/4 = 7 - x/3 -> multiply both sides by 3
9x/4 = 21 - x -> multiply both sides by 4
9x = 84 - 4x
13x = 84
x = 84/13
Answer:
(1.5,1)
Step-by-step explanation:
The midpoint of G and H is at (2,2).
The midpoint if J and K is (1,0)
The midpoint of the two midpoints is (1.5,1)
You could also i.e. directly ask for the midpoint of H an K, OR, G and J, and you would get the same final result.
Answer:
x = 2, y = 4
Step-by-step explanation:
3x - y = 2
3(2) - (4) = 2
6 - 4 = 2
x + y = 6
(2) + (4) = 6
6 = 6
