First: work out the difference (decrease) between the two numbers you are comparing. Then divide the decrease by the original number and multiply the answer by 100. If your answer is a negative number, then this is a percentage increase. :)
Answer: The first blank would be 71 and the second blank would be 32 and the 3rd blank would be 8
Step-by-step explanation: because on the first on it added by 7 so you would have to do the same for all of them.
Answer:
Option 3
Step-by-step explanation:
you have to multiply both of the terms
Simple, since you want to find y, in y=mx+b form, move everything to the other side.
1/2x-y=4
Move 1/2x
1/2x-y=4
-1/2x -1/2x
Making it look like,
-y=4-1/2x
Divide by the negative 1 in front of the y,
-y=4-1/2x
/-1 /-1
y=-4+1/2x
or
y=1/2x-4
Thus, this written in y=mx+b form, y=1/2x-4.
4 × 750 = 3 L so it will take 3 minutes for 4 canteens and
2 × 1.5 = 3 L it will also take 3 minutes
total it will take 6 minutes.
