Answer:
Step-by-step explanation:
Note that closed dot means that it is included inside. Look at the direction of the arrow, it will give you the knowledge of which way the sign will face.
10) x ≥ -1, or (4)
Note that the point is at -1 (-1), The arrow is also traveling towards the greater side (>). Note that the dot is 'colored in', or closed. If the dot is closed, the number the dot is on is included inside, leading to the sign having an equal sign on the bottom.
11) -4 ≤ x < 2, or (2)
As stated above ≤ means <em>closed dot</em> (or included). x is greater than -4, and so -4 is ≤ x. However, note the dot on the 2. It is not colored in. This means that 2 is not included inside the solution, leading to the usage of <.

Answer:
I saw this is recent so I cant explain to much because I dont know if your timed but 1.4 is equal to your number. all you got to do is 2.1 divided by 1.5
Step-by-step explanation
Answer:
275
Step-by-step explanation:
Cross multiply
36% of the boys = 99
100% of the boys = x
36/100 = 99/x ===> 36x = 99*100 ===> 36x = 9900 ===> x = 9900/36 ===>
x = 275 boys

Step-by-step explanation:
Answer:
1st = 17A => 17*21 = 357
2nd = A => 1*21 = 21
Step-by-step explanation:
17A + A = 18A
18A = 180
A=10
1st = 17A => 17*21 = 357
2nd = A => 1*21 = 21
