<span>5 nickels , 2 quarters, and 1 pennies = 8 coins.</span>
<span> he received 2 quarters</span>
in rectangular form the equation is 
Simplify both sides of the equation
x/16−(x+2/8) = 2x/16 + −1/8x + −1/4 = 2
Distribute
1/16x + −1/8x + −1/4 = 2
(1/16x + −1/8x)+(−1/4) = 2
Combine Like Terms
−1/16x + −1/4 = 2
Add 1/4 to both sides.
−1/16x + −1/4 + 1/4 = 2 + 1/4
−1/16x = 9/4
Multiply both sides by 16/(-1).
(16/−1)*(−1/16x)=(16/−1)*(9/4)
x=−36
Should take 8 minutes. I'm not totally sure; Pretty sure somebody else will get this right if I'm not.
You would do 5 divided by 4
the question is tells us that the sandwiches are being shared equally so it is the total amount. it is being distributed to 4 friends meaning it is being divided by 4.
5 divided by 4 = 1.25
they all got 1.25 of the sandwiches
