Answer:
12 marbles per bag
Step-by-step explanation:
Your equation would be 3x=x+24 because you have 3 bags of marbles with x number of marbles per bag, and your friend has 1 bag with x marbles plus 2 additional marbles
Then you solve this equation
3x=x+24
Subtract x from both sides
2x=24
divide both sides by 2
x=12
Answer:
2110 cm³
Step-by-step explanation:
Volume = V1 + V2,
Where V1 is the volume of the pyramid, and V2 is the volume of half cylinder
V1 = ⅓×(Base area)×height
V1 = ⅓×(12.6×21.5)×8.5 = 767.55
V2 = ½×(pi×r²×h)
r = 12.6÷2 = 6.3
V2 = ½×(pi×6.3²×21.5) = 1340.415
Volume = V1 + V2
= 767.55 + 1340.415
= 2107.965
= 2110 cm³ (3 sf)
