Answer:
-1<x<7
Step-by-step explanation:
We need to solve each inequality and then from the interval of numbers they both have in common (doing this because of the 'and').
x-2<5
Add 2 on both sides:
x<5+2
Simplify:
x<7
These are values of x that are less than 7.
x+7>6
Subtract 7 on both sides:
x>6-7
Simplify:
x>-1
These are values of x greater than -1.
So the values they have in common are the numbers in between -1 and 7.
That is x<7 and x>-1.
You can also write it as -1<x<7.
Maybe you need a graph to convince you more.

Answer:
B. What was the highest temperature this month?
Step-by-step explanation:
Rory is recording the <em>high</em><em>est</em><em> temperature</em> for the duration of the day for month's worth of data.
B. is the easiest one to answer, as you simply will have to look for the greatest number within the set, and that will be the answer.
A. is too broad, and does not imply that only the "high temperature" is needed, rather just a leveled temperature within day in that month.
C. is the opposite of what Rory had recorded, and without data, he cannot answer it.
D. is answerable as well, but, again, the only temperature recorded is the high temperature. Temperature can fluctuate depending on the time of the day, and can be in the 50s one hour and the 90s in another.
