Answer:
25 hours
Step-by-step explanation:
240 - 115= 125
125 divided by 5= 25
Answer:
Distance between the points
and
= 25
Step-by-step explanation:
The distance between two points in coordinate geometry can be find by using Distance formula.
If two points
and
are given then:

For points
and 
Distance=

The distance between the points is 25
Answer:
2.20
Step-by-step explanation:
The GPA is the weighted average of the grade points. The weights are the number of course hours.
((16 hours)(3.0) +(7 hours)(1.0) +(21 hours)(2.0))/((16 +7 +21) hours)
= 97/44 ≈2.20 . . . . GPA
Answer:
True
Explanation:
First of all its necessary remember that a linear system is a compound of multiple equations that involve variables.
<h2>Existence:</h2>
Depending on the number of equations and the number of variables, you could determine if the linear system has a solution or not. There are 3 possibilities:
- If the linear system has more equations than variables could exist infinite answers.
- If the linear system has more variables than equations, it is considered an undetermined system and you neer more information to solve it.
- If the linear system has the same number of equations and variables, the system is consistent and has at least one solution.
<h2>
Uniqueness:</h2>
If possibility 3 is presented, it becomes necessary know if its the only one solution or exists more than one solution.
