Answer:
Both of the angles will add up to 180 degrees so let’s make an equation.
5x-5+2x+10=180
First we collect like terms
5x+2x-5+10=180
Add them up
7x+5=180
Move the constant to the right
7x=180-5
7x=175
7x/7=175/7
x=25
So yes it’s true x=25.
Now we find the respective angles,
5x-5
5(25)-5
125-5
120
So angle one is 120 degrees.
2x+10
2(25)+10
50+10
60
So angle two is 60 degrees.
Now to check,
120+60=180
Step-by-step explanation:
Here we are give the value for π and Diameter of the circle fence
π=3.14
Diameter = 16
Radius = Diameter/2
2πr = 2(3.14)(8)
Circumference = 50.27
Now to fine the square fence length so we do 16*4 = 64
64-50.27 = 13.73 in
Therefore, the square fence is 13.73 inches longer than the circle fence
Answer:
Hi there!
The correct answer is: 5
Step-by-step explanation:
Essentially they replace x with 14, so all you have to do is plug 14 into the equation. 14 multiplied by 1/2 is 7, because it's the same thing as 14 divided by 2. Then you minus 2 from 7, and you get 5.
Answer:
Step-by-step explanation:
The initial amount was $300 and the final amount $350. This $50 change occurred in 4 weeks. Thus, the rate of change was
$50
----------- = $12.50/week for the first four weeks
4 wks
For the first nine weeks, the rate of change was
$400-$300 $100
------------------- = ----------------- = $0.11/week.
9 wks 9 wks
Note that this second result makes little sense. Ensure that you have copied this problem down correctly.
Only add 1 and 5 first, then your denominator would be 32 because 8 times 4 is 32.
