Answer:
The value of x = 38
Step-by-step explanation:
As we know that
The mean of a data set is the sum of the terms divided by the total number of terms.
Using math notation we have:
Mean = (Sum of terms) ÷ (Number of terms)
As
- Sum of terms = -3 + 10 + 22 + x + 28
so mean the equation becomes
Mean = (Sum of terms) ÷ (Number of terms)
19 = (-3+10+22+x+28) ÷ 5
19 × 5 = -3+10+22+x+28
95 = x + 57
x = 95 - 57
= 38
Therefore, the value of x = 38

Answer:
$15 per pair
Step-by-step explanation:
We know that the total amount of money she spent on the shoes (without discount) is 3x. Since she used a $10 off coupon, the money she spent is 3x - 10, since $10 off means - 10. And this amount equals $35:
![3x - 10 = 35\\3x = 45\\x = 45/3 \\x = 15](https://tex.z-dn.net/?f=3x%20-%2010%20%3D%2035%5C%5C3x%20%3D%2045%5C%5Cx%20%3D%2045%2F3%20%5C%5Cx%20%3D%2015)
