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.

3 1/4 = 13/4
so the reciprocal is 4/13
B
dividing with the same numbers and different exponents is like subtracting the exponents
16-8 = 8
Which lists the even numbers between 1 and 19 in set notation? A.{2, 4, 6, 8, 10, 14, 16, 18} B.{0, 2, 4, 6, 8, 10, 12, 14, 16,

D.
This is the only list that contains all even numbers that lie between the number 1 and the number 19.
I think it is the first and third one
