The angle on a line is 180°
The sum of the three given angles is 180°:
![(6x-10)+(x-5)+(x-5)=180](https://tex.z-dn.net/?f=%286x-10%29%2B%28x-5%29%2B%28x-5%29%3D180)
Use this equation to find the value of x:
![\begin{gathered} 6x-10+x-5+x-5=180 \\ 8x-20=180 \\ 8x=180+20 \\ 8x=200 \\ x=\frac{200}{8} \\ \\ x=25 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%206x-10%2Bx-5%2Bx-5%3D180%20%5C%5C%208x-20%3D180%20%5C%5C%208x%3D180%2B20%20%5C%5C%208x%3D200%20%5C%5C%20x%3D%5Cfrac%7B200%7D%7B8%7D%20%5C%5C%20%20%5C%5C%20x%3D25%20%5Cend%7Bgathered%7D)
Then, the value of x is 25
To isolate b, add a and subtract c to the entire equation:
D - a + c = -b
Muliply b by -1 to eliminate the negative:
-D + a - c = b
1. The formula for calculate the perimeter of a rectangle, is:
P=2L+2W
P is the perimeter of the rectangle (P=320 feet).
L is the lenght of the rectangle.
W is the width of the rectangle.
<span>
2. The problem says that the length of the rectangle is three times the width, so you have:
</span>
L=3W
3. When you substitute L=3W and P=320, into P=2L+2W, you obtain:
P=2L+2W
320=2(3W)+2W
320=6W+2W
8W=320
W=320/8
W=40 feet
4. The barn forms one end of the rectangle. Therefore the linear feet of fence (x) is:
x=P-W
x=320 feet-40 feet
x=280 feet
<span>
How many linear feet of fence must he buy?
</span>
The answer is: 280 feet
Answer:
$ 14.65 million
Step-by-step explanation:
The question requires you to add the profits obtained from the two years to get the net profit for the two years.
Profit in the first year of business = $ 6.25 million
Profit in the second year of business = $8.4 million
Net profits the last two years : $6.25 + $ 8.4 = $14.65 million
