It is 85 miles from central city to smithville and 125 miles from smithville to jonesburg. How many gallons of gas will it take to drive from central city to smithville to jonesburg in a car which gets 30 miles per gallon?

3 2/3

Step-by-step explanation:

add all the miles you get 110 divide it by the miles per gallon and you get 3.66666 or 3 2/3

my answer is$ 12

step-by-step explanation:

because 15 -2=12

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
