Simplifying:

5n + -7p + 3n = 25p

Reorder the terms:

5n + 3n + -7p = 25p

Combine like terms: 5n + 3n = 8n

8n + -7p = 25p

Solving:

8n + -7p = 25p

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '7p' to each side of the equation.

8n + -7p + 7p = 25p + 7p

Combine like terms: -7p + 7p = 0

8n + 0 = 25p + 7p

8n = 25p + 7p

Combine like terms: 25p + 7p = 32p

8n = 32p

Divide each side by '8'.

n = 4p

Simplifying:

n = 4p

Hope this helps!

5n – 7p + 3n = 25p

Combine like terms

8n - 7p = 25p

Add (7p) to both sides

8n - 7p + 7p = 25p + 7p

Simplifying

8n = 32p

Divide both sides by 8

8n / 8 = 32p / 8

Simplifying

n = 4p

An article in the Journal of Engineering Tribology discusses several experiments involving various lubricants. In one experiment

MrRa [10]

Answer:

the P value is 45.22%

Step-by-step explanation:

The computation of the P value is as follows;

Given that

standard deviation = 14.9

mean = 675

Reduction in diameter= 673.2

Based on the above information,

We have to applied the following formula i.e.

$Z = \frac{x - \bar x}{\sigma} \\\\= \frac{673.2 - 675}{14.9}\\\\= -0.1208$

Now the P value for -0.1208 is 0.4522 i.e. 45.22%

Hence, the P value is 45.22%

The same is to be considered
