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
The answer you have selected is correct. The answer to this question is 90.
Answer:
y=5/2x+6
Step-by-step explanation:
Y less than 21 = 21 - y
Remember, "less than" indicates a subtraction with the terms in inverted order.

In the standard form of the equation
![\\ \ f(t)=Acos[b(t\pm c)]+k\\ \\](https://tex.z-dn.net/?f=%20%5C%5C%20%5C%20f%28t%29%3DAcos%5Bb%28t%5Cpm%20c%29%5D%2Bk%5C%5C%20%5C%5C%20)
The middle line =k
For our given problem
f(t) = 40cos (80t + 20)
On comparison we get k=0
Hence middle line=0
