The average of 3,5,10 and X is 6, what is the value of X?
Rashid [163]
x = 6
The average of 4 numbers is 6, which means that (3 + 5 + 10 + x) all divided by 4 is 6. That means that 3 + 5 + 10 + x = 24, because 24/4 is 6.

18 + x = 24, subtract 18 from 24 to get x = 6.

Hey guys can u tell me if the top is correct if its not can u show me step by step what to do and what the answer will be and ca
ASHA 777 [7]
You have the right idea and you are close to the correct answer. However that's not what your teacher is looking for in terms of steps.

The starting inequality is b + 8 \ge 20
She starts off selling 8 buckets. Then she sells b more to get a total of b+8
This total must be 20 or larger which is why I set b+8 greater than or equal to 20

Solve for b by subtracting 8 from both sides

b + 8 \ge 20

b + 8-8 \ge 20-8

b \ge 12

So she needs to sell at least 12 more buckets to reach her goal

If you graphed this on a number line, then you would draw a closed circle at 12. Then shade to the right of the close circle.
