Answer:
38.5 = x
Step-by-step explanation:
9/ (x+2) = 2/9
Using cross products
9*9= 2(x+2)
Distribute
81 = 2x+4
Subtract 4 from each side
81-4 = 2x+4-4
77= 2x
Divide each side by 2
77/2 = 2x/2
38.5 = x
Answer:
50+x

Answer: Pyramid A: Base is rectangle with length of 10 meters and width of 20 meters.
Pyramid B: Base is square with 10 meter sides.
Heights are the same.
Step-by-step explanation: The volume of pyramid A is TWICE the volume of pyramid B.
If the height of pyramid B increases to twice the of pyramid A, (from 10m to 20m),
V of square pyramid = (10m)² * (10*2)/3 = 100m² * 20m/3 = 100m² * 6.67m = 666.67 m³
The new volume of pyramid B is EQUAL to the volume of pyramid A.
