Karl is building a rectangular garden bed. The length is 6 feet. She has 20 feet of boards to make the sides. Write and solve an
natali 33 [55]

Answer:

The width of the garden bed must be less than or equal to 4 feet.

w\leq4

Explanation:

Given that;

She has 20 feet of boards to make the sides.

The perimeter of the garden bed must not be more than 20 feet

\begin{gathered} P=2l+2w\leq20 \\ 2l+2w\leq20 \end{gathered}

Given;

The length is 6 feet;

l=6

To get the inequality for the width w, let us substitute the value of the length into the inequality above and simplify;

\begin{gathered} 2l+2w\leq20 \\ 2(6)+2w\leq20 \\ 12+2w\leq20 \\ 2w\leq20-12 \\ 2w\leq8 \\ \frac{2w}{2}\leq\frac{8}{2} \\ w\leq4 \end{gathered}

Therefore, the width of the garden bed must be less than or equal to 4 feet.

w\leq4

Five more than the product of a number and 4 is equal to 8
Maru [420]

Answer:

4x+5=8

x=\frac{3}{4}

Step-by-step explanation:

Let

x ---> the number

we know that

The algebraic expression is equal to multiply the number by 4, add 5 and equal 8

so

4x+5=8

Solve for x

subtract 5 both sides

4x=8-5\\4x=3

Divide by 4 both sides

x=\frac{3}{4}

37 1/2% of _________ is 36, Please help show work I am really confused.
klio [65]

Before you start working on this problem, make sure you know
how to use a couple of the tools in your toolbox:

Tool #1:  37-1/2 percent means 0.375

Tool #2:  In math problems, "of" almost always means "times".

====================================

Your question says

                           "37-1/2 percent of blank is 36".

Translate it with your tools:

                                  0.375  times  blank  =  36 .

Divide each side by 0.375:              Blank = 36 / 0.375 .

Now grab your pencil or your calculator, and find the value of that
fraction (do the division).  Blank is equal to the value of the fraction.


To check your answer (find out whether it's correct):

Do exactly what the question says.

Multiply (0.375) times (your answer).  If you get 36,
then your answer is correct.  If not, it's not.
