Given:

The equation is

-3(2x-3)=33

The incorrect solution steps are given.

To find:

The first error.

Solution:

We have,

-3(2x-3)=33

Using distributive property, we get

-3(2x)-3(-3)=33

-6x+9=33

The given step 1 is -6x+6=33, which is not correct.

Therefore, there is first error in step  1 because the distribution property is not used properly.

Hence, the correct option is D.

Safety regulations require that the time between airplane takeoffs (on the same runway) will be at least 2 minutes. When taking
Xelga [282]

Answer:

1 plane

Step-by-step explanation:

Let's suppose the number of planes waiting or on the runway " P "

the number of planes taking off per hour ' P_{takeoff}'

the time for waiting and the runway T_{wr} so:

P = P_{takeoff}   x T_{wr}

P_{takeoff} = 18 airplanes per hour

we know that 1 min = 60s

36s = 36/60 = 0.6 min

Also, 3 min and 30 s = 3 + 30/60 = 3.5 min

Next to find the time for waiting and the runway

∴T_{wr}= 0.6 + 3.5  = 4.1 min/60 (converting into hour)

T_{wr}= 0.068 hour

P = 18x0.068 = 1.23

therefore, there is 1 plane either on the runway or waiting to take off

So, there is 1 plane either on the runway or waiting to take off
