The length of the side of the original square is 7cm
Its a square pool and its perimeter is 100 yards.
We know that a square has 4 sides with the same length so we can give a square perimeter by the sum of their 4 sides
Lets call the side "l" and since we have 4 of them we need to sum it 4 times
l + l + l + l = perimeter
4l = perimeter
We know the perimeter
4l = 100
Divide both sides by 4
4l/4 = 100/4
l = 25
So the side length is equal to 25 yards
By proportion that would be 15/25 * 4 = 2.4 days
Answer:
a
Step-by-step explanation:
5x - 7 < 2x - 1
Take away 2x from both sides:
3x - 7 < -1
Add 7 to both sides:
3x < 6
Divide by 3 on both sides :
x < 2

Answer: x < 2
