You will be brainliest please list correct answer and the mistake he made
anzhelika [568]

<em>Hey There!!</em>

<em>The answer is below!!</em>

Step-by-step explanation:

We move all terms to the left:

-6n+22-(-4n+14-10n+22)=0

We add all the numbers together, and all the variables

-6n-(-14n+36)+22=0

We get rid of parentheses

-6n+14n-36+22=0

After that, We add all the numbers together, and all the variables

8n-14=0

Then, We move all terms containing n to the left, all other terms to the right

8n=14

n=14/8

n=1+3/4

<em>I don't know this is </em>100% right....

So.....GoodLuck!!

Rich measured the height of a desk to be 80.7 cm. The actual height of the desk is 80 cm. What is Rich's percent error in this c
Hitman42 [59]

Answer:

0.9%

Step-by-step explanation:

We have been given that Rich measured the height of a desk to be 80.7 cm. The actual height of the desk is 80 cm.

We will use percentage error formula to solve our given problem.

\text{Percentage error}=\frac{\text{Experimental value-Actual value }}{\text{Actual actual}}\times 100

\text{Percentage error}=\frac{80.7-80}{80}\times 100

\text{Percentage error}=\frac{0.7}{80}\times 100

\text{Percentage error}=0.00875\times 100

\text{Percentage error}=0.875\approx 0.9

Therefore, Rich's percent error in calculation is 0.9%.
