Required
Determine the cost of a table
Make T first equation
In the third equation, we have that:
By substituting 1275 for 2C + U
becomes
<em>Hence, a table costs $600</em>

Answer:
The base is 27 units long.
Step-by-step explanation:
This is a solve the system question. Call the length of the base B and the length of each leg L. We are told:
and
Sub the first equation into the second:
Now that we have the leg length, sub that into either of the original equations to find the base. I'll use the first equation:
