Answer:
4:2:3
Step-by-step explanation:
16 blue marbles,8 green marbles and 12 red marbles.
Ratio of blue to green to red
blue:green:red
16:8:12
We can divide each term by 4
16/4:8/4:12/4
4:2:3
2 to the first is 2 because there is only one 2
B) 17/6
First I multiply 2 times 6 which gave me 12 then I added 12 plus 5 which gave me 17 then I used the number at the bottom which is 6 so the final answer was 17/6

Answer: 1,2,3, and 5
Step-by-step explanation:
The isometries that preserve a shapes angles and line segments making the pre image congruent to the (post) image are :
Reflections, rotations, translations
These are rigid transformations. Think of your ruler. If you flip it, slide it, or rotate it around, did the ruler change shape? No. Just positions.
If you dilate something, you are either making it larger or smaller, therefore changing the size of the shape.
Anything that has dilation in its transformation does not have congruent shapes.
