Answer:
w = 
Step-by-step explanation:
We can find the formula for the width by isolating w:
V = lwh
Divide each side by lh to isolate w:
= w
X=4. First, you do 15/12 and get 1.25. You do this to see what number you have to multiply 12 to, to get 15. Since the sides a proportional it should be the same for the sides with their variables. Then you create an expression that puts the numbers the same place where 15 and 12 were to equal 1.25. You cross multiply, solve and get 4.
Answer:
Isolate Y and X? I am not sure if there is a full question for this but I think this is what you meant.
Step-by-step explanation:
We can solve for either:
y = -2x+7
y - 7 = -2x
y - 7 / -2 = x
That's x.
If you were asking for the slope intercept: y = mx + b
m = slope
negative opposite direction
etc.
