Mrs. traivs rode her bike 17.8 miles the first week, 21.5 miles the second week, and 13.4 the third week. the rest of her mileage was in the final week of the month. her total mileage for the month was 62.9 miles. [part a] use the numbers and symbols from the box to write an expression to represent the distance mrs. travis rode in the final week of the month. o ) [options: x, +, -, 62.9, 21.5, 17.8, 13.4] [side note: o can be x, +, or -.] [part b] use the expression to find the number of miles mrs. travis rode her bike in the final week of the month.

62.9 O/- 21.5+17.8+13.4 O/= 5.7
the final answer is Mrs.Travis rode 5.7 miles in the last week

(1,4)

Step-by-step explanation:

The number of visitors to the park as the temperature increases by x units is represented by the function: f(x) = 4x.The number of people who leave the park early depending on the change in temperature is represented by the function: f(x) = −x + 5.The graph of the two functions is plotted and attached below.The solution to the two functions is the intersection of the two lines: (1,4)The point of intersection is the temperature at which the number of people leaving the park is equal to the number of people in the park.The solution, (1,4) means that when temperature is at 1 unit, the number of people(4) leaving and entering the park is equal.
