When the family arrived in New Delhi from Rome, the youngest son asked the pilot how fast he was flying the plane. The pilot tol
Elden [556K]

Answer:

7 hours

Step-by-step explanation:

It is given that the plane was flying at 847 km/hour. So the speed of the plane was 847 kilometers per hour.

It is also given that the distance between Rome and New Delhi is 5,929 kilometers.

We know that the distance is equal to the product of speed and time, so we have,

d= s\times t, where 'd' represents the distance, 's' represents the speed, and 't' represents the time.

Putting the values we get,

5929= 847 \times t

Solving for 't' we get,

t= \frac{5929}{847}=7

So the time taken to fly from Rome to New Delhi is 7 hours.

Identify the solution(s) of the system of equations, if any.<br> -6x - 4y = 12<br> 12y = -18x - 36
UkoKoshka [18]
-6x - 4y = 12|\div 2\\&#10;12y = -18x - 36|\div 6\\\\&#10;-3x-2y=6\\&#10;2y=-3x-6\\\\&#10;-3x-2y=6\\&#10;-3x-2y=6

Both equations are equivalent, so there are infinitely many solutions.

Which of the following is a solution of y - x &lt; -3?<br><br> (6, 2)<br> (2, 6)<br> (2, -1)
Snowcat [4.5K]
Personally I'd solve this inequality for y first:  y < x-3.

That immediately eliminates (6,2) and (2,6).

Starting from y < x-3 and letting 2 sub for x and -1 sub for y, is the following true or false?

-1 < 2 -3     NO.  -1 < -1 is false.  Was there a fourth answer choice?
