Using the data you gave I made an equation
(x+3+11+9+7+3)/6 = x
(The formula for finding the mean is the sum of observations divided by total no of observations)
And I equated it (refer the picture)
x = 33/5 = 6.6
Hope this helped you!
1. 7
2. 15
3. 0
4. 5
Hopefully this is right, basically you are just turning negatives into positives I think.
To get 2 to 5, you multiply 2 by 2.5. do the same to 2/3 to get your answer. 2/3 times 2.5 = 2/3 times 5/2 equals 10/6 or 5/3 cups of sugar (1 and 2/3 cups of sugar) i believe
Answer:
-7/2
Step-by-step explanation:
2/3(6x - 18) = -26
divide by 2/3 or multiply by 3/2 (same thing)
6x - 18 = -39
add 18 to both sides
6x = -21
divide by 6
x = -21/6
simplify
x = -7/2
