Answer:
Polly=30
Andy=60
Phoebe=180
Step-by-step explanation:
Polly=x
Andy=2x
Phoeby 3(2x)=6x
x+2x+6x=270
9x=270
x=30
Polly=x=30
Andy = 2x=60
Phoebe=6x=180
To find out what 2 miles minus 3,333 yards is, first what you have to do is convert one unit to the other. I decided to convert 2 miles into yards. What you can do is multiple how ever many yards is one mile by two. So, there are 1,760 yards in 1 mile. 1,760 x 2 is 3,520. So now we have to subtract 3,520- 3,333.
The answer is 187.
It accelerates 80m/s in 20sec so 4m/s every second.
Circle equation
(x-h)^2 + (y-k)^2 = r^2
where (h.k) is the center and r is the radius
(x -7)^2 + (y+10)^2 = 4
