Answer:

This means x equals zero

Step-by-step explanation:

For example when I have: 3x + 5 = 5, my next step would be to subtract the 5 from both sides;

I end up with 3x = 5 - 5;

Then I get 3x = 0

After this I divide the 3 to both sides to isolate the x on one side.

x = 0/3

Whenever a zero is on the numerator of a fraction it equals zero, whenever the zero is on the denominator it is undefined and this is a mathematical error.

x = 0

-15 (0) = 0

(-15)x=0  

(-15) x = 0 ( divide by -15)

x = 0/-15 ( eliminate 0)

x = 0

Answer:

the first recipe

Step-by-step explanation:

We can answer by finding the ratio of nuts to cereal. The one that has the higher ratio of nuts to cereal is the nuttier one.

Recipe 1: 2 1/2 cups of nut per 5 cups of cereal.

nuts to cereal ratio = 2 1/2 : 5 = 1 : 2

Recipe 2: 1 cups of nuts per 3 cups of cereal.

nuts to cereal ratio = 1 : 3

1 : 2 is a higher ratio than 1 : 3

Make x the subject y=3x-2
Sedaia [141]
First, let's add the two from both sides.
y + 2 = 3x - 2 + 2
y + 2 = 3x

Now, all we have to do is to divide both sides by 3.
(y + 2)/3 = (3x)/3
(y + 2)/3 = x

And now, flip both sides around so it looks nicer.
x = (y + 2)/3
