So the train is pulling about 50 cars in total, and there's about 30 boxes of freight in each car.
30 x 50 = 1500
The best estimate would be near 1500 boxes of freight through the whole train.
Method 1: Realize that the desired equation will look exactly the same as the given equation 3x − 4y = 6, except that the constant will be different.
Thus, the equation of the new line is 3(-2) − 4(6) = C, where C comes out to 30.
Then the new line is 3x - 4y = 30.
If've shared an example it would be better
71/2 can also be written as 15/2, so divide 15/2 by 3/4. When you divide fractions you flip the second fraction and multiply it, so now it would be 15/2 X 4/3, so you would get 60/6 which is 10!
