Evaluate 4<br> M-n if m= -7 and n = 2.

gregori [183]

Answer:

-30

Step-by-step explanation:

I'm assuming the equation is $4m-n$ . If it is not please tell me.

If we know the values of m and n, we can just substitute inside the expression.

$4(-7) - 2\\\\-28 - 2\\\\-30$

Hope this helped!

A small airplane flies 1200 miles with an average speed of 300 miles per hour. 2 hours after the plane leaves, a Boeing 747 leav

inysia [295]

The small plane has the following parameters

Distance = 1200 miles

Speed = 300miles/hour

time = ?

$\begin{gathered} \text{Speed =}\frac{dis\tan ce}{time} \\ time\text{= }\frac{1200}{300} \\ \text{time = 4 hours} \end{gathered}$

If a Boeing 747 leaves 2 hours later, the total time becomes 4hours + 2 hours = 6 hours

Considering the distance of the small plane after 6 hours, we have

$\begin{gathered} \text{distance = sp}eed\times\text{ time} \\ d\text{ = 300 }\times6 \\ d\text{ =1800 miles} \end{gathered}$

So the total distance = 1800 miles

Hence the speed of the Boeing 747 will be

$\begin{gathered} \text{Speed =}\frac{dis\tan ce}{time} \\ \text{distance = 1800 miles } \\ time\text{ = 2hours} \end{gathered}$ $\begin{gathered} \text{speed = }\frac{1800}{2} \\ \text{speed = 900 miles/hour} \end{gathered}$

The average speed of the Boeing 747 is 900 miles/ hour

Two buses leave towns 520 kilometers apart at the same time and travel toward each other. One bus travels 16 km/h slower than th

vampirchik [111]

Answer:

122 km/h

138 km/h

Step-by-step explanation:

distance = speed * time

One bus travels 16 km/h slower than the other

(s * 2) + (s - 16)2 = 520

2s + 2s - 32 = 520

4s = 552

s = 552/4

s = 138 km/h

s - 16 = 122 km/h
