Choose what you think the expressions below best represent within the context of the word problem. a man traveled a certain number of miles by automobile and then nine times as far by airplane. his total trip was 600 miles in length. how far did he travel by plane?

540 miles

Step-by-step explanation:

Let the number of times he travelled by automobile be T. If he travels a certain number of miles by automobile and then nine times as far by airplane, then the number of miles by airplane would be

= 9T

If his  total trip was 600 miles in length then

T + 9T = 600

10T = 600

T = 60

By plane, he must have traveled

= 9 * 60 miles

= 540 miles

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
