Summary of problem.
annual production = 60000 units
work hours per worker = 200*12=2400 hours
productivity = 0.15 unit / person-hour
Need to calculate the number of workers/persons employed.
 
Each unit requires 1 unit / 0.15 unit/person-hour
= 1/0.15 person-hours / unit

60000 unit requires 60000 units * 1/0.15  person-hours/unit
= 400000 person-hours

400000 person-hours requires 400000 person-hours /2400 hours = 166.7 persons 
=>
The plant has 167 labourers  (assuming perfect attendance).

Solve the equation for x. Check the solution.<br><br> 2. -5(x + 3) = 20
Alona [7]

Answer:

x = -7

Step-by-step explanation:

-5( x + 3 ) = 20

Distributive property ( multiply whatever is in the parenthesis by -5)

-5 * x + -5 * 3 = 20

-5x - 15 = 20

Add 15 on both sides

-5x - 15 + 15 = 20 + 15

-5x = 35

Divide by -5 on both sides to isolate the variable

-5x/-5 = 35/-5

x = -7

Check...

Substitute the "x" with -7 since we already got that as our solution

-5( x + 3 ) = 20

-5( -7 + 3 ) = 20

Distributive property

-5 * -7 + -5 * 3 = 20

35 - 15 = 20

20 = 20 CORRECT

Hope this helped!

Have a supercalifragilisticexpialidocious day!
