After finishing his shift , a security guard wrote 6.75 "hours worked" on his time card . how long did he work?

6 hours 45 minutes.

Step-by-step explanation:

After finishing his shift, a security guard wrote  "6.75 hours worked" on his time card.

We have to calculate the time the guard has worked.

Now we convert (0.75) hours to minutes

0.75 hours = 0.75 × 60 minutes

                  = 45 minutes.

So total worked by security guard = 6 hours 45 minutes.

He worked 6 hours 45 minutes.

both equations and proportions are better.

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
