Answer:
12 feet
Step-by-step explanation:
Two buildings have the same total number of heights
The first building has 6 floors each with height h
The second building has a ground floor of 36 feet and 3 other floors each
Since both buildings have the same height then
Height of first building= height of second building
The first step is to calculate the height of the first building
Height of first building = 6h
The height of the second building is
36 + 3h
Therefore the height of each floors can be calculated as follows
6h= 36 + 3h
Collect the like terms
6h-3h = 36
3h= 36
h= 36/3
h= 12
Hence the height of each floors is 12 feet
Answer:
x = 3
Step-by-step explanation:
The equation is,
16 = 5x+1
Subtract 1 from both sides,
16-1 = 5x
15 = 5x
Divide by 5,
x = 3
Assume if it is cloudy, then you are outside.
The appropriate expression to identify the amount of formalin is: x = 3200 ÷ 100 × 44%
<h3>How to identify the amount of formalin?</h3>
To calculate the amount of formalin in this substance we must perform the following mathematical operation:
- 3200 ÷ 100 = 32
- 32 × 44% = 1,408
According to the above, the mathematical expression would be:
