Answer:
-7/3 =x
Step-by-step explanation:
5x-15 = 8x-8
Subtract 5x from each side
5x-5x-15 = 8x-5x-8
-15 = 3x-8
Add 8 to each side
-15+8 = 3x-8+8
-7 = 3x
Divide each side 3
-7/3 = 3x/3
-7/3 =x
Answer:
2cm
Step-by-step explanation:
The volume of water displaced by the rod is
v = πr^2 h = π * 3^2 * 8 = 72π cm^3
The drop in water level is the rod volume divided by the cross-section area of the tin, or
72π/(π*6^2) = 2 cm
