242.508488 Pounds in 0.11 metric tonnes
There's about 4400 lbs in a metric tonne, so 4400 * 0.11 = 484 lbs.
LambLamb didn't know for sure how many pounds were in a metric tonne. So LambLamb looked it up.
x = -b±√b²-4ac / 2a
A quick google search can tell you the quadratic formula.
Since Jamie bought exactly 3 more hot dogs than Amy at $4.50 more, the price of one hot dog must be $4.50/3 = $1.50. The cost of the soft drinks is irreleveant because the same amount was purchased by both people.
To cancel that -6, add 6 to both sides of the equation.
x > 60
I can tell you that the constant is negative 7. And I can tell you that the rate of change is negative 5.
It would look like a near-vertical line approaching the coordinate (1, 0), and stopping there.
If you are looking for the value of x, you would subtract 30 from both sides, then divide by 7.
7x+30 = 210
-30 -30
7x = 180
/7 /7
x = 25.714...
To calculate the mean (sometimes called average), you add up all the numbers and divide by the number of numbers you added up. (13+8+12+10+27)/5 = 14
Multiply all the numbers. The answer is 210.
