I am joyous to assist you anytime.
Not always. It depends on the teacher and the school. Depends on the rules and how your being tought.
Well, if the sulfur atoms is equal to 6 and the oxygen atoms is equal to twelve, then we are just multiplying by two so:
9 x 2= 18 so plug that in next
21 x 2=42
On the last one, you will want to divide by two to get the top
54/2=27
Hope I helped!
Answer: When y = -4, x = -10.
Explanation:
The equation for direct variation is y = kx^n, where k is the constant of variation. n is the exponent above the x value, but since this problem doesn’t involve exponents greater than one, we can ignore it.
First, find k.
y = kx
6 = k*15
k = 6/15 or 2/5
Now, we can solve for any x or y input. Let’s find x when y = -4.
y = kx
-4 = 2/5 * x
(to cancel out the fraction, multiply each side of the equation by its reciprocal, 5/2)
x = -4 * 5/2
x = -20/2
x = -10
