Answer:
J, 6
Step-by-step explanation:
plug in the values given into the equation
x = 5 and y = 2
4(5) - (2)³/ 2
20 - 8/2
20 - 8 = 18
12/2
6
the value of 
is 6 when the values are plugged in
4 Standard drinks he has consumed in over a two - hour time period.
<h3>What is Unitary Method?</h3>
The unitary method is a method in which you find the value of a unit and then the value of a required number of units.
For example: 5 cars have price of $500. what will be the price of 10 cars.
Now, we know
5 cars → $500
1 car → $500/5
1 car → $100
10 cars → 8 x $100
10 cars → $800
The standard drink contains 12 - ounce of beer.
Here, we have given 1 red cup which has 16 - ounce of beer.
He has 3 red cups.
So, total ounce of beer he has consumed in two hour time period:
16 x 3 = 48 ounce of beer.
Now, as we know standard drink contains 12 - ounce of beer.
so, Number of standard drink = 48/12 = 4
Hence, 4 Standard drinks he has consumed in over a two - hour time period.

Answer:
- Annie- 17 hours, Brian- 3 hours
Step-by-step explanation:
Let the number of hours Annie travelled be a, and same of Brian be b
<u>Then we have</u>
<u>Substituting a in the first equation</u>
- 5b + 2 + b = 20
- 6b = 20 - 2
- 6b = 18
- b = 3
<u>Then finding a</u>
<u>So the answer is:</u>
- Annie- 17 hours, Brian- 3 hours
(3 + (2/3))(2+(1/2) = 3*2+2*(2/3)+3*(1/2)+((2/3)(1/2)) = 6+(4/3) +(3/2) + (2/6) = 6 + ((8+9+2)/6) = 6 + (19/6) = 6 + 3 + 1/6 = 9 + 1/6 miles = D
A-
3x+6=18
3x=18-6
3x=12
X=4
A is the correct answer
