when is 9 = 15.2 - 0.537x
9 = 15.2 - 0.537x
-15.2 -15.2 subtract 15.2 from both sides
-6.2 = -0.537x
/-0.537 /-0.537 divide -0.537 from both sides
11.55 = x or 12 feet round to nearest whole foot
Answer:
7.39 ( nearest hundredth )
Step-by-step explanation:
Using the rule of logarithms
= n ⇔ x = 
Note that ln x represents
x
given 6 + ln x = 8 ( subtract 6 from both sides )
ln x = 2 ⇒ x =
≈ 7.39
The sum will be x+y because their ages are variables.
