Answer:
Number 21 is < number 23 is > number 22 is < and number 24 is >
Step-by-step explanation:
Since this is multiple choice ...
• check if B is correct:
x = 0, y = 4, z = 1 ⇒ 3x - y + 4z = -4 + 4 = 0 ≠ -10
(it's not)
• check if C is correct:
x = -2, y = 4, z = 0
⇒ 3x - y + 4z = -6 - 4 + 0 = -10
⇒ 3x - y + 4z = 2 + 4 + 0 = 6
⇒ 3x - y + 4z = -4 - 4 + 0 = -8
While this solution does satisfy the system, it can still have infinitely many other solutions that would work.
• check if D is correct:
Eliminate one of the variables from each equation. For instance,
(3x - y + 4z) + (-x + y + 2z) = -10 + 6
2x + 6z = -4
x + 3z = -2
and
(2x - y + z) + (-x + y + 2z) = -8 + 6
x + 3z = -2
but now it's impossible to eliminate one of the variables.
Therefore there are infinitely many solutions to the system [D].
The difference in the elevation between Mt.Everest and the Dead Sea is 29513 feet
<h3><u>Solution:</u></h3>
Given that,
Elevation of Mt.Everest = 29028 feet
Elevation of the Dead Sea = -485 feet
To find: difference in the elevation between Mt.Everest and the Dead Sea
Therefore,
Difference = Elevation of Mt.Everest - Elevation of the Dead Sea
Substituting the given values, we get
Difference = 29028 - ( - 485)
Difference = 29028 + 485 = 29513
Thus the difference in the elevation between Mt.Everest and the Dead Sea is 29513 feet
Graphs can be used to model real-world situations
- Segment 8 means: people are leaving the arena
- Segments 5 and 7 represent, intervals where there was no incoming or outgoing fans.
- Segment 6 means a few people left, when the game was going to an end.
Segment 8
From the graph (see attachment), we have the following observations
- Segment 8 is at the second half of the graph
- Segment 8 connects segment 7 and 9 (i.e. from the top, downwards)
The above points imply that:
Fans are leaving the arena at segment 8
Segments 5 and 7
From the graph, segments 5 and 7 are horizontal lines.
This means that:
No entry or exit was observed by the fans, at segments 7 and 5
Segment 6
Segment 6 connects segments 5 and 7, with a short downward line
This means that:
Few people left the arena, at segment 6
See attachment for the graph

Let 32% of x = 56
32%*x = 56
32/100 *x = 56
x = 56*100/32
x = 5600/32 = 175
hence, 32% of 175 is 56.
