Answer:
Step-by-step explanation:
These types of equations are called simultaneous equations and the method we can use to solve these type of equations is either Substitution, Elimination and Graphing.
We use substitution here because it is easier.
Equation 1
Equation 2
Lets take equation 1
This is our equation 3 , now put it inside equation 2.
We found the value of y , now to find the value of x insert the value of y in equation 3
Solved ! See the attached image on both the straight line graphs i have attached for better understanding. Where both the lines intersect each other is our value of (x , y) respectively.
Answer:
Total inventory: $175,000
Inventory in the stockroom: $35,000.
Inventory on the selling floor: $140,000.
Step-by-step explanation:
Let x be the the total inventory.
We have been given that in the Holiday Shop the manager wants 20% of the total inventory in the stockroom. You placed $35,000 of inventory in the stockroom.
We can set an equation such that 20% of x equals $35,000.
Since $35,000 of inventory in the stockroom, so we will subtract $35,000 from $175,000.
Therefore, $140,000 of the inventory on the selling floor.
Answer:
1. {5,-9}
2.{4}
3.{9/2}
Step-by-step explanation:
The equation can be solved as follows:
Then, the solutions of the equation are .
Now, if , we can solve the equation
as follows:
So, the unique solution of this last equation is
The last equation is , where
. To solve this equation we can proceed as follows:
But, x=11/4 is not a solution of this equation. So the unique solution is x=9/2.
