6.4 because a circle from side to is the same no matter where u start from and b plus d equal 6.4
Sum means to add up.
So: 263+378=641
Therefore the sum is 641
Number should be 2 instead of x .
<u>Step-by-step explanation:</u>
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 .
X= -2 is not the solution to the equation.
explanation: if you plug in -2 into -3–7, you get -1, and if you plug -2 into 5(x-1) you get -18.
