To solve this problem you must apply the proccedure shown below:

1. You have the following expression given in the problem above:

\frac{2}{x+2}+\frac{1}{5}=\frac{6}{x+5}

2. You need to sum the fractions located on the left member, as following:

\frac{10+(x+2)}{5(x+2)}=\frac{6}{x+5}

x=(12+x)(x+5)=6(5x+10)

3. Simplify it and you will obtain a quadratic equation. Solve it by factor out x:

x^{2} -13x=0\\ x(x-13)=0\\ x=0; x=13

Therefore, the answer is: x=0; x=13

Four different roads from Town A to Town B, and three different roads run from Town B to Town C. Two roads also run from Town A
LekaFEV [45]

Answer:

196

Step-by-step explanation:

To solve this, I broke it down into two parts.

A. Number of routes going to Town C

4 x 3 + 2 = 14

B. Number of routes going back to Town A

3 x 4 + 2 = 14

From here, it is easy to see what to do. Since there are 14 routes going to Town C and 14 routes going back, the answer is 14 x 14 = 196.

The circle below has a radius of 3 units . Find the area of the circle. Use 3.14 for π.
const2013 [10]

Answer:

28.26 units

Step-by-step explanation:

We know the radius of the circle is 3 units, so we'll end up plugging that into the formula.

A = π(3^2) or A = π * 3 * 3

When you substitute pi for 3.14, you'll end up getting 28.26 units.

Hope this helped! :)
