Answer:
$106.75
Step-by-step explanation:
Since the cost of a gallon of oil cost $3.05, we are going to have the equation y = 3.05x, where x represents the number of gallons of oil.
Since the Changs have 35 gallons of oil, the equation would be;
3.05(35) = 106.75
The Changs paid $106.75 for the delivery.
Answer:
13 gallons
Step-by-step explanation:
5/6 of a tank of gas to cross Arizona
Gas tank of her car = 15 1/2 gallons
ABOUT how many gallons did it take to cross Arizona
It takes 5/6 of 15 1/2 gallons of gas to cross to Arizona
5/6 of 15 1/2
= 5/6 × 31/2
= 155/12
= 12.92 gallons
Approximately to the nearest whole number is 13 gallons
Therefore, it takes 13 gallons of gas out of 15 1/2 gallons to cross to Arizona
The statement <span>The coefficient of x^k y^n-k in the expansion of (x+y)^n equals (n-k / k) is true. This will show the standard formula and the expansion of it. We all know that it can still be expanded based on the power or degree of the terms.</span>
Step-by-step explanation:
2500x=5000000
2500x/2500=5000000/2500
x=2000
I think the answer is this
