Answer:
A. 2f + 10 = 28
Step-by-step explanation:
28 candy bars.
He wants 10.
28 - 10.
18 candy bars.
He gives each friend 2.
18 divided by 2.
9.
He can treat 9 friends.
Step 1: Subtract 10 from both sides.
2f+10=28
which would take away the 10 and subtract 10 from 28. (That would be Jack's bars.)
2f = 28.
Step 2: Divide by 2 on both sides.
2f = 28
which would cancel out the 2f. And Whatever is done to the left is done to the right, meaning you would divide 28 by 2 aswell. (Dividing up the candy bars among his friends).
f = 9
Coordinates of mid point=(x1+x2/2 , y1+y2/2)
=(5+7/2 , 13+5/2)
=(12/2 , 18/2)
=(6 , 9)
Use this formula to get coordinates of mid point
here the coordinates of mid point are (6,9)
15.99 + 9.99 = 26
26 x 4 = 104
26 x 3 = 78
your answer is 3
