Step-by-step explanation:
The actual pressure before the percentage increase is 36.5
<h3>How to calculate the Actual pressure?</h3><h3 />
- New pressure = £39.42
- Percentage increase = 8%
let
39.42 = x + (8% of x)
39.42 = x + (0.08x)
39.42 = 1.08x
x = 39.42 ÷ 1.08
x = 36.5
Therefore, the actual pressure before the percentage increase is 36.5

Answer:
First, we have rounded numbers A and B, and we know that:
A + B = 11000
A - B = 3000
Now we can solve this system of equations as:
Isolating one variable in one of the equations, i will choose A in the second equation:
A = 3000 + B.
Now we can replace this into the other equation:
3000 + B + B = 11000
2*B = 11000 - 3000 = 8000
B = 8000/2 = 4000
and:
A - 4000 = 3000
A = 3000 + 4000 = 7000.
But remember that our original numbers are not exactly whole numbers, they are rounded up, so we could write them as:
A = 6999.8 (that would be rounded up to 7000)
B = 3999.7 (that would be rounded up to 4000)
The sum is:
A + B = 10999.5 (notice that this would be rounded up to 11000)
A - B = 3000.1 (this would be rounded down to 3000)
Answer:
Five pencils and two marches are worth greater than thirty paper clips.
Step-by-step explanation:
Let 'x' be paper clip.
Let 'y' be a match
and let 'z' be a pencil.
Now, let's write each statement as an equation:
Each paper clip can be traded for three matches:
x = 3y
Each pencil can be traded for six paper clips:
z = 6x
Now, five pencils equals 30 paper clips and two matches equals two thirds papel clips.
Therefore, we can say that Five pencils and two matches equals 30.66 matches. Therefore, five pencils and two marches are worth greater than thirty paper clips.
