2/5 ≥ x - (4/5). add 4/5 to each side
6/5 ≥ x
Answer:
226.2 feet
Step-by-step explanation:
The fence around the dog's house is a circle, with a radius of 12 meters.
To calculate the distance the dog runs, we need to find the circumference of that circle, which is given by the formula:
C = 2 π r, since we know r, the calculation is easy:
C = 2 π 12 = 24 π = 75.4 feet.
The dog makes three laps around the circle before calming down... so he runs 3 times 75.4 feet.
Dogs run = 3 x 75.4 ft = 226.2 feet
I got 168 because if you multiply 8x12 then you would get 96 and on the sides u need to multiply 3x12
3x - 2 = 13
Add 2 on both sides
3x - 2 + 2 = 13 + 2
3x = 13 + 2
3x = 15
Divide both sides by 3.
3x/3 = 15/3
x = 15/3
x = 5
Your final answer is A. 5.
