<span>The mathematical formula f(x + 1) = (f(x)) is like an arithmetic progression where the original value is f(x), an = f(x+1) , and d is equal to 1. In thsi case, if a0 is equal to x, then the progression should become x+1, x+2, x+3 and so on until x+n. There is no multiplication involved only addition process/</span>
Given:
Consider the below figure attached with this question.
Angles of a triangle are x, y and z.
To find:
The values of x, y and z.
Solution:
If two angles are linear pair, then their sum is 180 degrees.



Similarly,



According the the angle sum property, the sum of all angles of a triangle is 180 degrees.





Divide both sides by -5.

The value of x is 36.



Now,



Therefore, the values of x, y and z are 36, 67 and 77 respectively.
Speed = Distance/Time = 160/8 = 20 miles/hour
10+5=15 so $100/15= 6.67hrs. She could work about 7hrs.
she could work 7 hrs if rounded to nearest tenth
