One morning, Marcia works from 08 20 to 11 15. Find how long slie works for.
Give your answer in hours and minutes.

2:55. That's Two hours and 55 minutes.

Step-by-step explanation: From 8:20 to 11:20 would be three hours. But the actual time is five minutes less. There are 60 minutes in one hour. So change one hour to 60 minutes and subtract 5 minutes.

2:60 - :05 = 2:55

2 hours and 55 minutes

Step-by-step explanation:

Take 11:15 and subtract 8:20

11 : 15

-8:20

We need to borrow from the hours

11 becomes 10 and 1 hour = 60 minutes so add 60 to the 15

10 :75

-8:20

2: 55

This is 2 hours and 55 minutes

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

the aswere is the one with all 8's and the second one is with the 10,8 and 6
