<h2>6.</h2><h3>Given</h3>
<h3>Find</h3>
- The side length of a regular pentagon whose side lengths in inches are represented by these values
<h3>Solution</h3>
Add 27 to get
... 5x = 2x + 21
... 3x = 21 . . . . . . . subtract 2x
... x = 7 . . . . . . . . . divide by 3
Then we can find the expression values to be
... 5x -27 = 2x -6 = 5·7 -27 = 2·7 -6 = 8
The side of the pentagon is 8 inches.
<h2>8.</h2><h3>Given</h3>
- a rectangle's width is 17 inches
- that rectangle's perimeter is 102 inches
<h3>Find</h3>
- the length of the rectangle
<h3>Solution</h3>
Where P, L, and W represent the perimeter, length, and width of a rectangle, respectively, the relation between them is ...
.... P = 2(L+W)
We can divide by 2 and subtract W to find L
... P/2 = L +W
... P/2 -W = L
And we can fill in the given values for perimeter and width ...
... 102/2 -17 = L = 34
The length of the rectangle is 34 inches.
The total cost is $43.5 and it is obtained from the equation c = 6.5n + 25
<u>Solution:</u>
Given that, while your family is visiting Deep creek lake, you and your mother decide to go boating.
The Rangers charge $6.50 per hour in addition to $25.00 deposit to rent a canoe.
If you wish to rent the canoe from 12:30 to 3:30 PM,
We have to write and solve a linear equation to find the total cost to rent the canoe.
Now, we know that,
<em>total cost = charges + rent fee
</em>
![\text {Total cost }=\text { number of hours used } \times \$ 6.5 \text { per hour }+\$ 25](https://tex.z-dn.net/?f=%5Ctext%20%7BTotal%20cost%20%7D%3D%5Ctext%20%7B%20number%20of%20hours%20used%20%7D%20%5Ctimes%20%5C%24%206.5%20%5Ctext%20%7B%20per%20hour%20%7D%2B%5C%24%2025)
Let total cost be "c" and number of hours rented be "n"
![\begin{array}{l}{c=n \times 6.50+25} \\\\ {c=6.5 n+25 \rightarrow(1)}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bl%7D%7Bc%3Dn%20%5Ctimes%206.50%2B25%7D%20%5C%5C%5C%5C%20%7Bc%3D6.5%20n%2B25%20%5Crightarrow%281%29%7D%5Cend%7Barray%7D)
Now, they used canoe from 12:30 to 3:30, which means 3 hours of time
So, put n = 3 in (1)
c = 6.5(3) + 25
c = 19.5 + 25
c = 43.5
Hence, the total cost is $43.5 and it is obtained from the equation c = 6.5n + 25
Answer:
CI = 52-2x
Step-by-step explanation:
Answer:
x=84
Step-by-step explanation:
multiply 6.5 times 15.5 times 3.2 which will give you 322.4 so your area is 322.4 cm
