Elenna [48]3 years ago
4 0

Step-by-step explanation:

(7 + x) / 3 = 2x - 5

7 + x = 3(2x - 5) (multiply 3 on both sides)

7 + x = 6x - 15 (distributive property)

5x = 22 (arrange like terms)

x = 4.4 (divide 5 on both sides)

Hi there! Hopefully This helps!

<h2><em>Answer: The mean number of this data set is 43. The mean represents the average number of minutes Julio practiced on his trumpet for 6 days.</em></h2>

Explanation:

<u><em>To find the "mean" you need to count how many numbers are in the data set. Then add up all the numbers in the data set. </em></u>

In this case you have six numbers in the data set, and all the numbers added up together(21+30+39+43+58+67) are 258.

<u><em>After adding up all the numbers, divide them by how many numbers are in the data set.</em></u>

258/6 = 43.
