- You buy a bunch of 12 bananas and pay $6 and want to know how much each banana costs.
- You pull into a gas station where the gas is $2.50 a gallon. You want to know how much you would need to fill up your 35 gallon tank.
- You drove 300 miles to visit your cousin in another state. It takes you 4 hours. You want to know how many miles you drove per hour.
The unit consumption of gas can be obtained by dividing the total distance traveled in miles by the total gallons of gas consumed by the trip. This is shown below:
121.72 miles / 6.8 gallons = 17.9
Therefore, on a gallon of gas, Amir can travel 17.9 miles, which is letter B among the choices.
The answer is standard form is 3,300,200

Answer:</h3>
x² -6x = -13 ⇒ x ∈ {3-2i, 2+2i}
<h3>
Step-by-step explanation:</h3>
To make a=1, divide the equation by the coefficient of x², which is 8.
... x² -6x = -13 . . . . . . your blanks are filled with -6 and -13
Now, to complete the square, add the square of half the x-coefficient:
... (-6/2)² = 9.
... x² -6x +9 = -4 . . . 9 added to both sides
... (x -3)² = -4 . . . . . rewrite as a square
... x -3 = ±2i . . . . . . take the square root
... x = 3 ±2i . . . . . . . add 3
The solutions are the complex numbers x = 3 ±2i.
