Step-by-step explanation:
Let x be the number of logs=18 hours
6 logs=4 hours
X*4=18*6
4x=108
x=27 logs
so therefore 27 logs are needed to keep the fire burning for 18 hours
Answer:
C. two thirds x + 10 = 21
Step-by-step explanation:
Given
Price of adult ticket = $21.00
Let x be the price of student ticket
Then
two third of the student ticket will be:

The statement $10.00 more than two third of student ticket:

As we are given in the question that the adult ticket price is $21.00 and the second explanation is th equation formed by the given statement
So, both will be equivalent

Solving this equation for x will give us the price for the student ticket.
Hence,
C. two thirdsx + 10 = 21 is the correct answer ..
<span>Northwest is 45 degrees north of west. If a car travels a distance x miles northwest, its northerly component gains x/sqrt(2) miles and its easterly component LOSES xsqrt(2)/ miles.
Resultant height is h = 4500 + 100x/sqrt(2) - 75x/sqrt(2) = [25/sqrt(2)]x + 4500
dh/dt = [25/sqrt(2)]dx/dt = [25/sqrt(2)]v </span>
2/3 = 8/12
1/4 = 4/12
You start with 8/12 and eat 4/12 so 4/12 (or one quarter) remains.
3ft per second on a still sidewalk (27/9) , 11ft on the moving sidewalk.(99/9)
