Tomtit [17]
Lets have 4x acres of soybeans , then it is going to be 9x acres of corn
(4x/9x=4/9)

Altogether he planted 400  acres
So, we can write
4x+9x=400
13x=400
x=400/13

4x acres of soybeans  
4*400/13≈123 acres of soybeans

Solve: 2 In 3 = In(x-4)
jeka57 [31]

Answer:

x = 13

Step-by-step explanation:

one of the rules of logarithm (for all bases, by the way, not just e for ln) is

a \times  ln(b)  =  ln( {b}^{a} )

so, we have

ln(3²) = ln(x-4)

=>

3² = x - 4

9 = x - 4

x = 13
