Shown in the Figure below
Step-by-step explanation:
In this exercise, we have the following system of inequalities:
The word and means intersection, so both inequalities must be true at the same time. We can graph this system as indicated in the figure below. Indeed, there is intersection between -1 and 1. Also, the number -1 is included in the solution because 
and this is represented by the closed circle. On the other hand, the number 3 is not included in the solution because 
and this is represented by the open circle.

8 + 4 = 3x
12 = 3x
divide both sides by 3
x= 4
Answer:
The shape is a reduction, and the scale factor is actually 2/3.
Step-by-step explanation:
Answer:
56 total
Step-by-step explanation:
Let the number of girls = x
Let the number of boys = 3x
x 1
=== = ==========
x + 28 3
Cross multiply
3x = x + 28 Subtract x from both sides
3x - x = 28 Combine
2x = 28 Divide by 2
x = 28/2
x = 14
Girls = 14
Boys = 14 + 28 = 42
Is the ratio 3 to 1?
42/14 = 3/1 Yes it does
Total number
14 + 42 = 56
