Tristan wants to ride his bicycle 27 miles this week. He has already ridden 9 miles. If he rides for 6 more days, which tape diagram could be used to represent the context if
X represents the average number of miles he would have to ride to meet his goal?

Eric has challenged himself to walk 24,000 steps in 4 days. if eric walks the same number of steps each day, which function represents the number of steps eric still needs to walk to reach his goal with respect to the number of days since he started his challenge? a. y = 8,000x − 24,000 b. y = -8,000x + 24,000 c. y = 6,000x − 24,000 d. y = -6,000x + 24,000

Ineed in figuring out this problem.

We just started the introduction into circles and i have no idea how to do this.
