Answer:
Step-by-step explanation:
use substitution and solve this 8x+4(-2x+3)=12
with the 4 distributed its
8x-8x+12=12
then you can cancel out the 8x and -8x and switch the 12 over into a -12 canceling out the 12s making it x=0
Answer:
Step-by-step explanation:
65%
Step-by-step explanation:
Given: Full capacity= 200000 litres
Amount of fuel used during flight= 130000 litres
Now, finding percentage of fuel used on the flight.
∴ Percentage of fuel used=
Solving it, we will get
∴ 65% of fuel capacity been used in this flight.
