It can be done.
You must take a few steps to set it up, but then you are able to count 7 minutes. The setup makes you be able to time 2 minutes on the 5-minute sandglass and then you do another 5 minutes on the same sandglass.
Setup:
Start both sandglasses at the same time. When the 5-minute sandglass runs out, the 8 minute sandglass has 3 minutes of sand left. At this moment, start the 5 minute sandglass again.
When the 8-minute sandglass finishes the remaining 3 minutes, the 5-minute sandglass has 2 minutes left.
Actual timing of 7 minutes:
Let the 2 minutes pass, and immediately turn over the 5-minute sandglass to count an addition 5 minutes. The last 2 minutes of the 5-minute sandglass plus an additional 5 minutes of the 5-minute sandglass add to 7 minutes.

Step-by-step explanation:
<span> The coordinates of point P on a coordinate grid are (−5, −6). Point P is reflected across the y-axis to obtain point Q and across the x-axis to obtain point R. What are the coordinates of points Q and R? Q(5, 6) and R(−5, −6) Q(−5, −6) and R(5, 6) Q(−5, 6) and R(5, −6) Q(5, −6) and R(−5, 6). </span><span>
