Answer:
x - 5 = 9
x = 14
Step-by-step explanation:
On the left side, there are 5 -1's and 1 x. On the right side, there are 9 1's. Then we set them equal and solve
Problem:
x - 5 = 9
+ 5 + 5
x = 14
I would go with number 3.
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.
It will be 6/10.
just do 6÷10= 0.6
