Mean= (5+6+5+6+9)/5= 7.2 coins
Explanation: The mean is the average of a data set. Add the numbers from the data set and divide by how many numbers.
<h2><u>
Answer:</u></h2>
x = 3
y = -8
<h2><u>
Step-by-step explanation:</u></h2>
x + y = -5
x - y = 11
Since the y's will cancel out, we don't need to modify the two equations in any way.
Now, just add the two equations.
x + x = 2x
y + (-y) = 0
-5 + 11 = 6
2x = 6
Divide by 2.
x = 3
To find y, plug 3 in as "x" in one of the two equations.
3 + y = -5
y = -8
Answer:
D is the equation of the circle
Answer:
24.7 miles takes 1 gallon of gas
Step-by-step explanation:
314÷12.7=24.724409 which gets rounded to 24.7
Y + 4 = -4 (x - 6) ...point slope equation form
