Isolate the a. Note the equal sign. What you do to one side, you do to the other.
Add 5 to both sides
-5 (+5) + 1/5a = 4 (+5)
1/5a = 9
Isolate the a. Multiply 5 to both sides
(5)(1/5)a = 9(5)
a = 9 x 5
a = 45
45 is your answer for a.

Answer:
0.33333
Step-by-step explanation:
Answer: 1,393 meters tall
Step-by-step explanation:
Plug in 1710 meters for the initial amount, 0.05 for the rate of decrease, and 4 millennia for the time elapsed.
y
= a(1–r)t
y
= 1,710(1–0.05)4 Plug in values
y
= 1,710(0.95)4 Subtract
y
= 1,710(0.81450…) Simplify
y
= 1,392.80568… Multiply
Round to the nearest whole number.
1,392.80568… → 1,393
To the nearest whole number, the mountain will be 1,393 meters tall.
The distance between points 
and 
can be calculated using formula
