Given:
The expression is
![8p+3q-18](https://tex.z-dn.net/?f=8p%2B3q-18)
To find:
The value of the expression when
and
.
Solution:
We have,
![8p+3q-18](https://tex.z-dn.net/?f=8p%2B3q-18)
Putting
and
, we get
![8(\dfrac{1}{2})+3(7)-18](https://tex.z-dn.net/?f=8%28%5Cdfrac%7B1%7D%7B2%7D%29%2B3%287%29-18)
![=4+21-18](https://tex.z-dn.net/?f=%3D4%2B21-18)
![=7](https://tex.z-dn.net/?f=%3D7)
Therefore, the value of the expression is 7 when
and
.
Answer:
Step-by-step explanation:
Economics is a branch of social science and it deals with more of observations, theories, laws, deductions and construction of abstracts model.
So, to do all of these, economists need to be good at mathematics to approach some of these abstracts model.
Like all other scientist, economists also do hypothesis to allow them study the economy growth and help them construct a model that solve this goals these requires a lot of mathematical models and abstract reasoning. They usually employ mathematical and graphical models and analysis to solve the economic issue e.g. demand and supply curves analysis
Economic models usually employ graphical and mathematical analysis to help explain and illustrate such economic processes.
All of these makes economic very hard to study. So to study economics, you need to be good at mathematics

Answer: 25
Step-by-step explanation:
From the question, we are informed that the piece of rural land sold ten years ago for 40000 and that the price for the same land this year is $800 more per acre, and it sold for 60000.
The size of the piece of land in acres will then be:
40000 + 800x = 60000
800x = 60000 - 40000
800x = 20000
x = 20000/800
x = 25
The land is 25 acres
