I think is C,,,,,,,,,,,,,
The number of athletes that finished the race this year was 4284 athletes.
What is percentage?
10%, a comparative figure denoting one hundredth of any quantity. One percent, denoted by the symbol 1%, is equal to one hundredth of something; hence, 100 percent denotes the full thing, and 200 percent designates twice the amount specified.
Let x represent the amount of athletes that finished the race this year.
Last year, 3,570 athletes finished the Silvergrove Marathon. This year, the number of runners crossing the finish line was 20% higher. Hence:
x = 3570 + 20% of (3570)
x = 3570 + (0.2 * 3570)
x = 4284
4284 athletes finished the race.

Answer:
width = 150 yards
length = 200 yards
Step-by-step explanation:
Using the information given to us, we can make the following two equations:
2L + 2W = 700
L = W + 50
where L is the length in yards and W is the width in yards. This could treat these two equations as a system of linear equations. There are multiple ways to solve a system of linear equations, but I am going to solve this by substitution. Before doing that, I am first going to simplify the first equation, as it will make solving the system easier.
2L + 2W = 700
Divide both sides by 2.
L + W = 350
Since L = W + 50, we can substitute W + 50 for L in the equation L + W = 700.
(W + 50) + W = 350
2W + 50 = 350
2W = 300
W = 150
Now that we found what W is, we can solve for L by plugging 150 into either one of the equations. I am going to plug it into the equation L = W + 50.
L = 150 + 50
L = 200
Now we found what L is. So now we know that the width is 150 yards and the length is 200 yards.
I hope you find my answer and explanation helpful. Happy studying. :)
Answer:
let the amount of time needed to sew 49 pair of trousers be x
If 1 pair of trousers = 57 minutes
49 pairs of trousers = 49 × 57/1
= 2793 minutes
Hope this helps.
