Answer:
x =35
Step-by-step explanation:
The sum of the angles of a triangle add to 180
x+10 +x + 3x-5 = 180
Combine like terms
5x+5 = 180
Subtract 5 from each side
5x+5-5 =180-5
5x = 175
Divide by 5
5x/5 =175/5
x =35

The required number of minutes a person used the phone is 131 minutes.
Given that,
A cellular phone company charges $25 per month plus 10 per minute of phone use. A person's bill came to $38.10 for one month,
<h3>What is simplification?</h3>
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Let x be the number of minutes he used the phone,
According to the question,
25 + 0.1x = 38.10
0.1x = 38.10 - 25
0.1x = 13.10
x = 13.10/ 0.1
x = 131 minutes
Thus, the required number of minutes for the given condition is 131 minutes.
