Lets say, I bought 3 cakes in the store and I spent $300, how much does a cake cost?
The equation representing that situation is the following, calling x the cake cost, our unknown factor:
3x = 300
we can solve this equation by dividing all equation by 3:
x = 100
therefore each cake costs $100

I want to buy eight bracelets, I don't know how much each bracelet costs, but the final cost will be $39.67.
The equation would look like this:
8 x <em>c</em> = 39.67
Where <em>c</em> equals cost.
To find the answer I would do the following:
8 x <em>c </em>= 39.67
<em>c</em> = 39.67 / 8
<em>c</em> ≈ 4.95
Each bracelet costs about $4.95.

Explain how solving 4x &lt; -16 is different from solving -4x&lt; 16.
nalin [4]

Answer:

Dividing by 4 and -4

Step-by-step explanation:

Solving 4x < -16 is different from solving -4x< 16, because for 4x < -16, you are dividing by a positive 4 on both sides, but for -4x< 16, you are dividing by -4 on both sides.
