Answer:
m》9
Step-by-step explanation:
-1/3 m 《-3
Multiply both sides by -3
(Don't forget to flip the inequality
m》9
Adding the systems of equations together, we get
2x=88
Dividing both sides by 2, we get x, or the number of women, to be 44.
Plugging that into either equation, we get
44-y=18. Adding y to both sides and subtracting 18, we get y, or the number of men, to be 26.

4(x+x+7) x=1
4(1+1+7)
4+4+28 = 36
(-2x+7-4) x=2
-2(2)+7-4
-4+7-4 = -1
Answer:
Step-by-step explanation:
38=2(5)+2(x ) find X
2x5-10
38-10=28
28/2=14
14/2=7
x =7
so you length is 7
X = length of third side
The third side is unknown and can't be determined to be one fixed number. However, we can find a set of values or a range of acceptable values
If we know that
a = 6
b = 7
are the two given sides, then we can say
b-a < x < b+a
7-6 < x < 7+6
1 < x < 13
So the third side x can be between 1 and 13.
The third side cannot be equal to 1 unit or 13 units because a triangle would not form. Instead a straight line would form.
Note: This idea is using the triangle inequality theorem
