I will use 'hr' to mean hour and 'hrs' to mean hours.

<u>The airplane flies:</u>

200 miles per hr

400 miles per hr

600 miles per hr

Average speed = Total distance ÷ total time

= (200 + 400 + 600)miles ÷ 3hrs = 400miles/hr

Time = Distance ÷ Average speed

= 2000miles ÷ 400miles/hr = 5hrs

1) 9m

2) 1/64

3) 50d^3

4) pq^2 (p-q) (p-q)

= pq^2 ( p^2 - 9p -9p +18)

= pq^4 - 18p^2q^2 + 8pq^2

= q^2 - 18p + 8

A number subtracted from -50 amounts to 171 what is the equation
shtirl [24]
-50 - (-221) = 171

This is because subtracting a negative number is like adding a positive version of that instead. For a more simple example:
5 - (-2) = 7 or 5 + 2 = 7
