Answer:

Mary worked 7 and a half hours.

Step-by-step explanation:

The easiest way to solve this is converting to the 24 hours metric.

In this metric, 8:10 am is 8h, 10 min.

3:45 pm is 12+3 = 15h, 45 min.

Rounded to the nearest quarter hour, Mary worked 15-8 = 7h, 45-10 = 35 min, Mary worked 7 and a half hours.

First we count how many hours is inbetween 8 and 3  which is 7

then subtract 10 for the first time

6:50 then add 45 for the second time

7:35

round down so she worked 7 1/2 hours

What is the value of x, given the following system of linear equations? x + y = 8 and x - y = 2
zaharov [31]

Answer:

x = 5

Step-by-step explanation:

x + y = 8 \\ x - y = 2 \\ x + y + (x  - y) = 8 + 2 \\ x + y + x - y = 10 \\ 2x = 10 \\  \frac{2x}{2}  =  \frac{10}{2}  \\ x = 5 \\  \\ x + y = 8 \\ 5 + y = 8 \\ y =  8- 5 \\ y = 3 \\  \\ x - y = 2 \\ 5 - 3 = 2 \\ 2 = 2
