Answer:
A,D, and F
Step-by-step explanation:
All of those answers are a fraction or decimal meaning when you multiply it by any whole number your number will get smaller. (Image will be smaller than pre-image)
D. it represents the product of two rational numbers and is equivalent to an irrational number
Let us assume the first number = x
Then the second number = 5x -2
The third number = x + 4
The total number that needs to be divided into three parts is 219
Then we can write the equation as
x + 5x - 2 + x + 4 = 219
7x + 2 = 219
7x = 219 - 2
7x = 217
x = 217/7
= 31
Then
First number = 31
Second number = 5x - 2
= (5 * 31) - 2
= 155 -2
= 153
Third number = x + 4
= 31 + 4
= 35
So the three numbers are 31, 153 and 35.
