Answer:

Length of the shorter pipe is 0.55 meters.

Step-by-step explanation:

Let the length of one longer pipe = x meters and the length of shorter pipe = y meters

Now we will form the equations to get the length of shorter pipe or value of y.

x = 7y -----(1)

x - 2.2 = 3y ----(2)

Now we put the value of x from equation 1 to 2.

7y - 2.2 = 3y

7y - 3y = 2.2

4y = 2.2

y = 2.2/4 = 0.55 meters

Therefore the length of the shorter pipe is 0.55 meters.

Express a(2) (2a(-1/2)+a) in its simplest form
Soloha48 [4]
First lets simplify the first term and yield (2a)

The second term:
1.   2a * (-1/2) = -a
2.   -a + a = 0

Now we have simplified both terms to: (2a) (0)

Anything multiplied by 0 is 0, so the answer is also 0.
