2x+4(x-1)=2+4x [First, you would distribute the 4 into the x and -1]
2x+4x-4=2+4x [Then combine like terms(2x+4x)]
6x-4=2+4x [Next, subtract common numbers (6x-4x)]
2x-4=2 [Then you would combine like terms (2+4)]
2x=6 [Finally, divide the 2x by 6]
x=3
Hope this helped!
Answer:
D no its not
Step-by-step explanation:
If the ratio is 7 to 1, the width of the wing must be 1/7 of the length. So, we just divide 26.7 by 7 to get 3.81 meters.
Answer:
It'll take 10.6638 years to double his money.
Step-by-step explanation:
Since the invested capital is compounded continuosly we need to use the apropriate formula shown below:
M = C*e^(r*t)
Where M is the final value, C is the initial value, r is the rate of interest and t is the total time elapsed. In this case we want to double our investment, since the amount invested was 2800, then we need to have a final value of 2*2800 = 5600. Applying these values to the formula:
5600 = 2800*e^(0.065*t)
2800*e^(0.065*t) = 5600
e^(0.065*t) = 5600/2800
e^(0.065*t) = 2
ln(e^(0.065*t)) = ln(2)
0.065*t = ln(2)
t = ln(2)/0.065 = 10.6638 years
It'll take 10.6638 years to double his money.
