2x - 5y = 9
2x -9 = 5y
(2x -9) /5 = y
x= -1
(2(-1) -9)/5 =y
(-2 -9) / 5 = y
-11/5 = y
x=0
(0-9)/5 = y
-9/5 = y
x=1
(2(1) - 9) /5 = y
-7/5 = y
Ok well you could just type the question then we could help
Step-by-step explanation:
V= π r^2h
^
Pi
First you need the radius, if the diameter is 10inches divide by 2 = 5 inches, that's your radius.
π(5inches)^2 times (20 inches)
firsr work out 5^2= 5x5= 25
π(25inches) times (20inches)
25x20=500π inches
500π =1,570.7963267948966192313216916397514420985
which rounds to 1,570, the first one is your answer
