7x1=7, then 4x1/4= 4x1=4 divided by 4= 1. Then subtract 7- 1= 6
Answer:
Step-by-step explanation:
A plane leaves the airport at 9:15pm and travels at speed 560km/h then at midnight plane will be at 1540 km far away.
As given,
Plane leaves the airport at 9:15 pm
Plane travels at speed of 560 km /h
Total time = 2hour+ 45minutes
= 2hour+ (45/60)hour
= (11 /4) hour
We have
1 hour = 560 km
⇒ (11 /4)hour = (560 ×11)/4 km
= 1540 km
Therefore, a plane leaves the airport at 9:15pm and travels at speed 560km/h then at midnight plane will be at 1540 km far away.

Simple....
you have: 4(x+7)
To simplify it..distribute..
4(x+7)
4*x=4x
and
4*7=28
Leaving you with...
4x+28
As we can see B is 4x+28
Thus, your answer.
It is 28 pounds. This is because all of the others have a ratio of 4:1 while 28 and 5.5 have a ratio of 56:13.
