Answer: B. (1/200 = x/19.5)
EXPLANATION
Space shuttle Atlantis model scale 1:200
Length of Atlantis on model = 19.5
The actual length of Atlantis = x
Find x
Scale = 1:200; in decimal = 1/200
When length on model = 1
Actual length = 200
When actual length = x
Length on model = 19.5
Scale = x:19.5 ; in decimal = x/19.5
Equating both scales,
1/200 = x/19.5 (Option B)
Answer:
Jean is 9 and Tom is 15.
Step-by-step explanation:
3 years ago, Tom was 12 and Jean was 6, hence Tom was twice as old as Jean.
Since that was their age 3 years ago, they are currently 15 (Tom) and 9 (Jean).
Add 2 years to each of these ages, you get 17 and 11.
17 + 11 = 28
We are given x so we can plug it in to the first equation to find y
11 - y = 6
We don’t want y to be negative so we subtract y from both sides
11 = 6 + y
Now we can subtract 6 from both sides
5 = y
