N=-6
-6 minus 6 is -12
-12 /3 is -4 since the negative doesn’t cancel out
16. no i dont agree. 1 is the only number that can multiply and equal itself. also, 0.1 is not even a whole number
17. it took 19 to 21 hours. one way to show work is by long division. i dont know how to do another way im so sorry
18. because 15000 is the amount in 50 minutes, so just divide 50 minutes of phones by 50 to get one minute of phones
i am worn out i cant do the last one
Answer:
Step-by-step explanation:
A well defined set is one which is universally defined and accepted, you can easily define what the set is and what is not a member of the set.example is a set of integers between 1 and 30
A not well defined set is one which is ill defined set. example is a list of hit musical hit of 2019
The missing values are 28° and 62°
<h3>What are perpendicular lines?</h3>
Perpendicular lines are said to be two lines that intersect or meet each other at right angles, that is 90 degrees.
From the information given, we have that;
Line AC ⊥ Line BE
Where:
- m ∠ ADE = (x + 5)°
- m ∠ DBE = (3x - 7)°
Hence,
x + 5 + 3x - 7 = 90
collect like terms
4x = 90 + 2
4x = 92
Make 'x' the subject
x = 92/ 4
x = 23
For the missing values
m ∠ ADE = (x + 5)° = ( 23 + 5) = 28°
m ∠ DBE = (3x - 7)° = (3(23) - 7) = 62°
Thus, the missing values are 28° and 62°

X by its self is always 1x
1x+8=-15 you have to get rid of 8 by subtracting on both sides
1x=-23 now get rid of 1 by dividing on both sides
x=-23
