Solve 27 = 3^4x + 1? a) 1/4 b)1/2 c)2 d)4

B

Step-by-step explanation:

27 = 3^3

3 = 4x + 1

2 = 4x

x = 1/2

Step-by-step explanation:

i assume that by 5 you mean 5 gallons.

(20)(0.25) = 15

removing 15 gallons reduces the tank from 20 to 5.

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

see the picture for the graph.
