Agata [3.3K]3 years ago

Answer:   4 = n

Step-by-step explanation:

5n + 34 = -2(1-7n)

Distribute negative 2 to both 1 and negative 7n. You do this first due to the rules of PEMDAS

5n + 34 = -2 + 14n

Add two to both sides of the equation in order to further isolate (n) in 14.

5n + 36 = 14n

Subtract 5n from both sides of the equation so that the values with (n) are on one side of the equation.

36 = 9n

Divide nine from 36 and 9n in order to isolate (n).

4 = n

This then gives you your final answer.

vazorg [7]

Answer

Find out the what is the percent error in the measurement, to the nearest tenth of a percent .  

To prove

Formula

Percentage\ error = \frac{error\times 100}{exact}

Where error = | Approx - Exact |

As given

Karen measures the width of a garden plot and records that it is 44.25 meters. Its actual width is 45.5 meters.

Approx value = 44.25 meters    

Actual value = 45.5 meters        

error = | 44.25 - 45.5 |

         = |-1.25|

         = 1.25

Put in the formula

Percentage\ error = \frac{1.25\times 100}{45.5}

Percentage\ error = \frac{125}{45.5}

Percentage error = 2.7%

Therefore the percentage error is 2.7% .

Cara started working for $9 per hour. She earns a 4% raise every year. What is her
shutvik [7]

Answer:

Caras hourly wage is $10.08 after 3 years

Step-by-step explanation:

4% of 9

0.04 x 9 = 0.36

then you multiply 0.36 by 3 because you are solving for 3 years.

0.36 x 3 = 1.08

then you add 1.08 to 9 because Cara's wage goes up $1.08 in 3 years

1.08 + 9 = 10.08

answer:

Cara's hourly wage is $10.08 after 3 years of working
