The answer is: 21x-28
Answer: 7/16
Step-by-step explanation:
Distance of the relay race = 1 3/4 miles
Number of runners for the relay team = 4 runners
Distance to be run by each runner will be:
= Distance of the relay race / Number of runners
= 1 3/4 ÷ 4
= 7/4 ÷ 4
= 7/4 × 1/4
= 7/16
Each runner will run 7/16 miles
The answer is 4 1/2 and that's the answer

Answer:
The situations 1 and 2 describes an equal difference over an equal interval.
Step-by-step explanation:
1. A sunflower grows at a rate of 3.5 cm per day, for the first 28 days.
Here, the growth of the sunflower per day is uniform i.e. 3.5 cm.
2. After the car is purchased the value of a car depreciates at a rate of 15% per year.
Here, also the the depreciation of the car's value is equal i.e. 15% of initial value per year.
