Given the simultaneous equations


Subtract the equations







∵ 














Similarly,








Answer:
200
Step-by-step explanation:
156.7
since the number before the hundred is more than 4
it becomes 200
The greatest number of tables that can be made is; 24 tables
<h3>Limiting Resources</h3>
To determine the limiting factor;
- We must divide the number of all factors available by 72.
Hence, it goes that;
- Only, 48/72= 0.66 balloons per chair
- Only 24/72 = 0.33 flowers per chair
- Only 32/72 = 0.44 candles per chair
However, it follows from the question that; the same number of centerpieces be used on each table.
Hence, the ratio of flowers per chair is lowest and hence, 72×0.33 flowers are used, 24 tables can therefore be set up.

An operational definition can both define and measure the hypothetical construct. The hypothetical construct is also called psychological construct is an explanatory variable which cannot be directly observed. It is also a tool to understand someone’s behavior. For example measuring you friend happiness.
In this equation x = 49.
In order to find this, follow the order of operation of solving equations.
1/7x - 5 = 2 -----> Add 5 to both sides
1/7x = 7 ----> Multiply both sides by 7
x = 49
