Expand and simplify (x+3)(x+5)

A number,x, decreased by the sum of 2x and 5 represent what equation

Annette [7]

We set up this expression that we have to simplify. Although, to make it an equation, we set the expression given equal to the variable y, making this a function too.
y=x-(2x+5)
distribute the negative symbol
y=x-2x-5
combine like terms
y=-x-5
and that is our final answer

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

Mariana [72]

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 $\boxed{\bf9.73\,{\bftext{Pounds}}}$ .
