A car is traveling on a small highway and is either going 55 miles per hour or 35 miles per hour, depending on the speed limits, until it reaches its destination 200 miles away. Letting xx represent the amount of time in hours that the car is going 55 miles per hour, and yy being the time in hours that the car is going 35 miles per hour, an equation describing the relationship is: 55x+35y=20055x+35y=200

c. If the car spends no time going 35 miles per hour, how long would the trip take?

1. 34

2. 268

3. x=14.4

step-by-step explanation:

step-by-step explanation:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
