The family trip to Grandma's consisted of both a train ride and a car ride. The average speed of the train ride was 74 miles per hour, and the average speed of the car ride was 50 miles per hour. The entire trip lasted 10 hours.
Let x be the number of hours the train ride lasted. Write an expression for the total distance of the trip, in miles.

Arefrigeration system at your company uses temperature sensors fixed to read celsius (°c) values, but the system operators in your control room understand only the fahrenheit scale. you have been asked to make a fahrenheit (°f) label for the high temperature alarm, which is set to ring whenever the system temperature rises above –10°c. what fahrenheit value should you write on the label

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126

Complete the solution of the equation. find the value of y when x equals to 6 4x+y=20
