Hey there! Instead of trying to explain, I’ll give you a visual of the way I calculated it.
I attached a photo.
I hope this helps and if you have questions about it, post them in chat! Happy to help.

Answer:
The answer is "778"
Step-by-step explanation:
Given value:

The formula for z-score:
Answer:
35 1/2 divided by 1 1/4 then 27 1/5 divided by 4/5
For the blue car the answer is 28.4.
For the red car the answer is 34.
So 30/48=15/(x+9)
this could be easily solved by recognizing the proportion (the other way is usiing full algebra and doing multiply both sides by 48(x+9) and then divide both sides by 30 then subtract 9)
30 is 2 times of 15
therefor 48 is 2 times of (x+9)
48=2 times (x+9)
divide both sides by 2
24=x+9
subtract 9
15=x
x=15
