A table and 8 chairs weigh 235.68 lb together. If the table weigh 157.84 lb, what is the weigh of one chair in pounds

Verified Answer :

9.73 is the weight of one chair. if you take 235.68 and minus 157.84 you get 77.84. you then take that number and divide it by 8 to get your answer of 9.73.

The weight of one chair is \(\boxed{\bf9.73\,{\bftext{Pounds}}}\).

Further explanation:

The weight of a table and eight chairs is 235.68 pounds together.

Let the weight of a chair be \(x\).

Then, weight of eight chairs will be eight times  \(x\) that is  \(8x\).

It is given in the question that weight of a table is 157.84 pounds.

According to the given information, the mathematical equation for the statement that a table and 8 chairs weigh 235.68 lb together is written as,

\(8x+157.84=235.68\)

Above linear equation contain all the information of a given question.

On Solving the above linear equation as shown below, we obtain a unique value of \(x\).

\(\begin{aligned}8x+157.84&=235.68\hfill\\8x&=235.68-157.84\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\left({{\text{Subtract}}\,157.84\,{\text{from}}\,{\text{both}}\,{\text{sides}}}\right)\hfill\\8x&=77.84\hfill\\x&=\frac{{77.84}}{8}\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\left({{\text{Divide}}\,{\text{by}}\,8}\right)\hfill\\x&=9.73\hfill\\\end{aligned}\)

From the above calculation, the unique value of \(x\) is 9.73.

We assumed that variable \(x\) denotes the weight of one chair.

Thus, the weight of one chair is \(\boxed{\bf9.73\,{\bftext{Pounds}}}\).
