The sum of three consecutive odd numbers is 63. What is the smallest of these numbers?
2 answers:
Answer: The smallest number = 19
Step-by-step explanation:
We'll call X the smallest of those odd numbers
Then x + (x+2) + (x+4) = 63
X + X + 2 + X + 4 = 63
3X + 6 = 63
3X = 63 - 6 = 57
X = 57/3 = 19
The three consecutives odd numbers are 19, 21, 23
The sum = 19+21+23 = 63
Your answer : The smallest number = 19

Answer:
2002 pounds
Explanation:
To know the weight of the plane, we need to find an equation that relates the amount of fuel to the weight.
This equation can be founded using the following
Where m is the slope, x1 is the number of gallons and y1 is the respective weight. So, replacing m = 6.0, x1 = 51 gallons and y1 = 2206 pounds, we get:
Now, we can solve for y
Then, we can calculate the weight of an airplane with 17 gallons of fuel replacing x = 17 on the equation above
y = 6x + 1900
y = 6(17) + 1900
y = 102 + 1900
y = 2002
Therefore, the answer is 2002 pounds
