Jonas has the following data: 2, 5, x, 2, 4, 3. if the average is 3, what number should be instead

Number should be 2 instead of x .

Step-by-step explanation:

Here we have , Jonas has the following data: 2, 5, x, 2, 4, 3. if the average is 3, We need to find  what number should be instead x . Let's find out:

We know that

Where is terms and n is the number of terms . Let's find average for 2, 5, x, 2, 4, 3 which is 3 :

⇒

⇒

⇒

⇒

⇒

Therefore , Number should be 2 instead of x .

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
