#1 w=9 because:
2w+2(2w+3)=60
2*2w=4w and 2*3=6
2w+4w+6=60
Then: 2w+4w= 6w
6w+6=60
I just tried each answer I knew it had to be 8 or 9
So I tried 8 and it didnt work then I tried 9 and it did
6*9= 54+6=60
w=9 
#2  I have a picture for this one I worked it out on paper. Check out the photo for the answer :)
Hope this helps!

If 3x+13= 19, find the value of 4x +1
12345 [234]

Answer:

It would be 8

Step-by-step explanation:

It would be six because 13 plus 3 is 16 and the answer was 19 so I added 3 more and I got 19. So that made me think that the value of x is 3. :)

The mean of a sequence of n numbers is m. If we split the sequence into two sequences of lengths n1 and n2 and compute their mea
Furkat [3]

The mean of a sequence of numbers is the average.

The true statement is: \mathbf{mn = m_1 \times n_1 + m_2 \times n_2}

The given parameters are:

\mathbf{Mean = m}

\mathbf{Size = n}

The mean of a dataset is calculated as:

\mathbf{Mean = \frac{\sum x}{Size}}

So, we have:

\mathbf{m = \frac{\sum x}{n}}

Multiply both sides by m

\mathbf{\sum x = mn}

When the sequence is split into two, we have:

\mathbf{\sum x_1 = m_1\times n_1}

\mathbf{\sum x_2 = m_2\times n_2}

Where:

\mathbf{\sum x_ = \sum x_1 + \sum x_2}

So, we have:

\mathbf{mn = m_1 \times n_1 + m_2 \times n_2}

Hence, the true statement is: \mathbf{mn = m_1 \times n_1 + m_2 \times n_2}
