Answer:
problem 1 2x+5y= 0
×=-1/2-5/2y
problem 2 y=1 3/7y y=-1.428571
7y=-10
problem 3 x=-7
problem 4 x-y=20
x=-20
The answer is -125. Get this by taking (-5)(-5)(-5)
Answer:
14.6m
Step-by-step explanation:
volume of a hemisphere = (2/3)πr3
Therefore r = Cube root of ( Volume * 3/2 * 1/ pi)
r = cube root ( 6466 * 3/2 * 1/ π)
r = 14.56
in the nearest tenth of a meter = 14.6 m
Answer:
8
Step-by-step explanation:
Lines have angles that are equal to 180. Therefore, because we already have 140 of the 180 necessary, we can subtract 140 from 180 to get 40. 40 divided by 5 is 8.
