Solve in 2 + in x= 5. round to the nearest thousandth, if necessary.

The value of x nearest to thousandths is 74.207

Solution:

Given that,

------ eqn 1

We can use logarithmic properties to solve for "x"

Using logarithmic properties:

Therefore, apply the above property in eqn 1

By using the logarithmic property,

Apply the above logarithmic property in above expression

Solve the above equation

We know that,

Therefore,

Therefore, the value of x nearest to thousandths is 74.207

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon
