Answer:

-2x +4 = 20

Step-by-step explanation:

given

- 2x + 4 = 20

by making x the subject, you need to subtract 4 from 20

thus

- 2x = 20 - 4

- 2x = 16

and also you need to divide through by -2

\frac{ - 2x}{2}  =  \frac{16}{ - 2}

x =  - 8

Can someone help me my grade are bad
Likurg_2 [28]

Answer:

8.31

Step-by-step explanation:

Using the Pythagorean Theorem:

a^2+b^2=c^2

10^2+b^2=13^2

100+b^2=169

b^2=69

b = \sqrt{69}

b = 8.306623863

The side length for x, rounded to the nearest hundredths, would be 8.31.

kodGreya [7K]

Answer:

27525.4902

Step-by-step explanation:

First need to add the total number of employees:

14+11+17+3+5+1=51

Now multiply the salary for each number of employees then add to have the total:

14x21000+11x22800+17x24800+3x32200+5x38500+1x148300= 1403800

Now to obtain the mean value just divide the total salary by the total number of employees:

1403800/51= 27525.4902

the mean salary is $27,525.49
