Answer:
we must get more than 4 digs in the remaining 3 games break record of 20
Step-by-step explanation:
given data
current volleyball season = 16 digs
games left in the season = 3
previous record = 20 digs
solution
we consider here the number of digs x that must get in the remaining 3 games to break your record
so for break previous record of 20 digs, we have to get more than 20
so 16 digs must add to x to greater than 20
x + 16 ≥ 20 ...............................1
so x will be
x ≥ 20 - 16
x ≥ 4
so that we must get more than 4 digs in the remaining 3 games break record of 20
I calculated the expression and I got 22.
Answer:
Part 67)
and 
Part 68)
or 
Step-by-step explanation:
Part 67) we know that
The solution of the number line is the interval -------> (-2,3)
All real numbers greater than -2 and less than 3
so
The compound inequality could be
and 
"And” indicates that, both statements must be true at the same time
Part 68) we know that
The solution of the number line is the interval (-∞,-1] ∪ [1,∞)
All real numbers less than or equal to -1 or all real numbers greater than or equal to 1
The compound inequality could be
or 
"Or” indicates that, as long as either statement is true, the entire compound sentence is true
