A rectangle of perimeter 74 cm is 7cm longer than it is wide. what is the length of each side?​
Mumz [18]

I assume that you mean: the length is 7cm more than the width, and the perimeter is 74 cm.

If so, we can write down the following system, where l and w represent, respectively, the length and the width:

\begin{cases}l=w+7\\2(l+w)=74\end{cases} \iff \begin{cases}l=w+7\\l+w=37\end{cases} \iff \begin{cases}l=w+7\\(w+7)+w=37\end{cases}

We can easily solve the second equation:

(w+7)+w=37 \iff 2w+7=37 \iff 2w=30 \iff w=15

And finally solve for the length:

l=w+7=15+7=22

Find the values of x that satisfy
mr_godi [17]
Setup 2 problems
2x - 7 < 15   and    2x - 7 > -15
2x < 22                  2x > -8
x < 11                    x > -4

Or you can write it  -4 < x < 11

Brut [27]

Answer:

x=5

Step-by-step explanation:

(5x+2)/3 = 9

Multiply each side by 3

(5x+2)/3 *3 = 9*3

5x+2 = 27

Subtract 2 from each side

5x+2-2 = 27-2

5x = 25

Divide by 5

5x/5 = 25/5

x =
