Answer:
x=5 y=-6
Step-by-step explanation:
3x+y=9 ------eqn1
y=4-2x -------eqn2
using substitution
put y=4-2x into eqn1
3x+4-2x=9
x=5
put x=5 into eqn2
y=4-2(5)
y=4-10
y=-6

Answer:volume of cone = 170.5 ft³
Explanation:The volume of the right circular cone can be calculated as follows:
volume =

We are given that:
diameter = 6.1 ft.......> This means that: radius (r) = 6.1 / 2 = 3.05 ft
height (h) = 17.5 ft
Substitute with the givens in the above equation to get the volume as follows:
volume =

volume = 170.477 which is approximately 170.5 ft³
Hope this helps :)
Hey there!
4x = –28
DIVIDE BOTH of your SIDES by 4
4x/4 = –28/4
CANCEL: 4/4 because that gives you 1
KEEP: –28/4 because it helps us solve for “x”
x = –28/4
–28/4 = –7
Answer: x = –7 ☑️
Good luck on your assignment and enjoy your day!
