If x-15=30,what is the value of 2(x 5)
Digiron [165]
X - 15 = 30
=> x = 30 + 15 = 45

2(x + 5) = 2(45 + 5) = 2(50) = 100

This is a double question. Part 1: 5(2x - 4) = 30. Solve for x Part 2: 5x + 3 - x + 2 = 41. Solve for x. I will mark Brainliest
Ainat [17]

Answer:

see below

Step-by-step explanation:

Part 1: 5(2x - 4) = 30.

Distribute

10x -20 = 30

Add 20 to each side

10x-20+20 =30+20

10x = 50

Divide by 10

10x/10 = 50/10

x =5

Part 2: 5x + 3 - x + 2 = 41

Combine like terms

4x +5 = 41

Subtract 5 from each side

4x+5-5 = 41-5

4x = 36

Divide by 4

4x/4 = 36/4

x = 9

The data set below has 7 values. Find the mean absolute deviation for the data set. If necessary, round your answer to the neare
Svetach [21]

Given:

The data set is 13, 14, 15, 6, 17, 16, 3.

To find:

The mean absolute deviation for the data set.

Solution:

We have,

13, 14, 15, 6, 17, 16, 3

Mean of the data set is:

\text{Mean}=\dfrac{\text{Sum of all observations}}{\text{Number of observations}}

\overline{x}=\dfrac{13+14+15+6+17+16+3}{7}

\overline{x}=\dfrac{84}{7}

\overline{x}=12

The formula for mean absolute deviation is:

MAD=\dfrac{\sum_{i=1}^n|x_i-\overline{x}|}{n}

Using this formula, the mean absolute deviation for the data set is:

MAD=\dfrac{|13-12|+|14-12|+|15-12|+|6-12|+|17-12|+|16-12|+|3-12|}{7}

MAD=\dfrac{1+2+3+6+5+4+9}{7}

MAD=\dfrac{30}{7}

MAD\approx 4.29

Therefore, the mean absolute deviation for the data set is about 4.29.
