Answer:
He can give 4 friends pieces of a candy bar.
Step-by-step explanation:
Each person has to have exactly 3/4 a candy bar.
If you divide all 3 1/2 candy bars into fourths, you will have 14 pieces.
So then, take out portions of 3 at a time, so take out 3 of these pieces, you have one friend. Take out another 3 pieces you now took 6 out and gave to 2 friends. Take another three and you've taken out 9 pieces for 3 friends. Take one more set of 3 pieces you now have taken out 12 pieces for 4 friends. There are only 2 more pieces left which is not enough for another friend so you have 4 friends that got some chocolate.
Hope this helps!! :)

Answer:
b) Substitute (3x - 5) for y in the second equation.
Step-by-step explanation:
If using the substitution method, then the second choice is the most efficient first step.
<u>What is the substitution method?</u>
The substitution method can be used to solve a system of equations. It is when you isolate any of the variables from one of the equations and then substitute that value into the other equation.
Here, the first equation already has an isolated variable, y. We can then substitute its value into the second equation. Like so:
⇒ 2x + 6y = 20
⇒ 2x + 6(3x - 5) = 20
