Answer:
the ratio used was 1:19
Step-by-step explanation:
let a be the action figure version
let r be the real iron man
let's list out the important things.
a = 4''
r = 6'4''
one foot has 12 inches
convert r into inches:
6 × 12 = 72 (6 feet in r)
r = 76'' (72 + 4)
r = 76''
a = 4''
ratio is 4:76
simplify
4:76
2:38
1:19
the ratio they used is 1:19

If f(x) = 15, then rewrite the equation replacing the f(x) with 15
15 = 2x + 9
subtract 9 from sides
15 - 9 = 6
9 - 9 = 0
then, you would be left with 6 = 2x
divide by 2 on both sides
6/2 = 3
2x/2 = x
x would be 3 :)
