Answer:
the number of hamburgers sold on Thursday were 325.
Step-by-step explanation:
The total number of hamburger and cheese burger is missing
i will replace it with any figure, you can replace it wit your given data and you will get the solution.
A local hamburger shop sold a combined total of 593 hamburgers and cheeseburgers on Thursday
There were 57 fewer cheeseburgers sold than hamburgers
How many hamburgers were sold on thursday
Let h be the number of hamburgers and c be the number of cheeseburgers.
Using this information we can set up two equation as:

Now we need to solve these two equations to get the value of number of hamburgers. For that we use substitution method as shown below:

Therefore, the number of hamburgers sold on Thursday were 325.

Determine the additive inverse of each
The rule of additive inverse is as follows;
- For any positive number (n), the additive inverse is (-n)
- And for any negative number (-n), the additive inverse is (n)
Using the above, the solution is as follows:

Rule: <em>6 becomes -6 and - (-3) becomes +(-3)</em>
So, the additive inverse is 

<em />
Rule: <em>-6 becomes 6 and -3 becomes 3</em>
So, the additive inverse is 

Rule: <em>6 becomes -6 and -3 becomes 3</em>
So, the additive inverse is 

Rule: -<em>6 becomes 6 and -(-3) becomes +(-3)</em>
So, the additive inverse is 
<em />
For x^2+x-6/x-7=0, I think it should be x=~2.59262 or x=~-2.75153 or x=~-0.84108
