-3 (-4 + -x ) = (-4(x) × 2 ) + 6
-3 (-4-x) = (-4x × 2) + 6
-12 + 3x = -8x + 6
3x - 12 = 6 - 8x
add 8x on both sides
11x - 12 = 6
add 12 on both sides
11x = 18

Answer:
Volume=469cm³
Step-by-step explanation:
[tex]
Volume,V=Volume Cone + Volume\ of Hemisphere\\\\
Volume Cone,V1=\pi*r^2*\frac{h}{3}=\pi*4^2*\frac{12}{3}\\ \\
=201.06cm^3\\
Volume of Hemisphere,V2=2*\pi*\frac{r^3}{3}\\
=2*\pi*\frac{4^3}{3}=268.083cm^3\\
Volume=V1+V2=201.06+268.08\\
=469cm^3

2000 for RF and IT and EF per month...
30% goes to retirement.....0.30(2000) = 600
IT is 80% of RF.....0.80(600) = 480
remainder goes to EF.......2000 - (600 + 480) = 920
which represents 20% of his salary...
920 = 20% of salary (s)
920 = 0.20s
920/0.20 = s
4600 = s.........he earns 4600 per month <==
