Answer: Yes, they are similar- and the Scale Factor is 2.5
Step-by-step explanation: To find the scale factor, simply divide the larger number on the bigger shape by its counterpart in the smaller image, so for example: 60 divided by 24 is 2.5, and there is your scale factor. You can further test this by multiplying 4 x 2.5 which gives us 10, the other value on the larger shape.
Answer:
3 3/5 as an improper fraction = 18/5
Let the number be X. Then we find
7X + 3 = 39 - 2X
Now we collect the terms and find
9X = 36
Finally we divide by 9
X = 4
So our answer is 4
