a table and 8 chairs weigh 235.68lb together if the table weighs 157.84 lb, what is the weight of one chair in pounds
2 answers:
The weight of one chair is .
Further explanation:
The weight of a table and 8 chairs together is .
The weight of the table is 157.84 lb.
Therefore the weight of 8 chairs is calculated as follows:
The weight of 8 chairs is obtained as 77.84 lb.
Consider the cost of 1 chair as .
Then the cost of 8 chairs can be written as .
Therefore the equation can be written as follows:
Here, represents the weight of 1 chair.
Thus, the weight of 1 chair is obtained as .

The domain of a function f(x)/m(x) = 1/√x(x² - 4) is (0, ∞) - {0, 2, -2} for other function is shown in the solution.
<h3>What is a function?</h3>It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have:
f(x) = 1/√x
m(x) = x² - 4
Domain of f(x)/m(x):
f(x)/m(x) = (1/√x)/(x² - 4)
f(x)/m(x) = 1/√x(x² - 4)
The denominator cannot be zero:
√x(x² - 4) ≠ 0
x(x - 2)(x+2) ≠ 0
x ≠ 0, 2, -2
and x > 0
Domain of f(x)/m(x) is: (0, ∞) - {0, 2, -2} or
Domain of f(m(x)):
f(m(x)) = 1/√(x² - 4)
x² - 4 > 0
Domain:
Domain of m(f(x)):
= ((1/√x)² - 4)
Domain:
Thus, the domain of a function f(x)/m(x) = 1/√x(x² - 4) is (0, ∞) - {0, 2, -2} for other function is shown in the solution.
