160 km - 100%
100%+30%=130%
160*130%:100%=208 (km) - <span>the number sought</span>
4(x - 5) = 3x + 7
4x - 20 = 3x + 7
x - 20 = 7
x = 27
Hence there is only one solution. These types of equations are called linear equations and linear equations have a degree of 1, which means they have only one solution.
To help answer your question, a quadratic equation (an equation of degree 2) has 2 solutions, 1 solution, or no solutions (imaginary solutions).
I hope this helps ya.
Answer:
Half of 2 is 1(new radius)
1^1 = 1
1 x 3.14 = 3.14
Now we multiply the area of the circle by the height to get the volume.
3.14 x 3 = 9.42
He said he would pay 3.18 per every square foot so now we multiply 3.18 by 9.42.
9.42 x 3.18 = 29.9556 rounded = it is around $30.
The answer is -11
