24. To find the mean add all of the numbers and divide the sum by the number of digits you added. Meaning that you would add 25, 15, 18, 20, 87, 13, 8, 22, and 14 which is 240 and divide that by 10 since there are 10 numbers. Hope that this helped, have a blessed day :)
Answer:
(-2,2)
Step-by-step explanation:
To solve the system, set the equations equal and solve for x.
x + 4 = -2x - 2
3x + 4 = -2
3x = -6
x = -2
Substitute x = -2 into one of the equations.
y = -2 + 4
y = 2
The solution is (-2,2).
Answer:
x = 16
Step-by-step explanation:
So we do the fancy inverse thing:
x - 4 + 4 = 12 + 4
x = 16
