10 trains

Step-by-step explanation:

9 trains = 6 are full

15 trains = x are full

9/6 = 15/x      Cross Mutiply

9x = 90          Divide 9 on both sides

  x = 10

10 trains

Step-by-step explanation:

The proportion of full trains to trains is 6 to 9, 6/9

We can set 6/9 equal to x/15, because we want to know how many full trains there would be

6/9=x/15

Cross multiply

9x=90

Divide by 9 on both sides,

x=10

So of the next 15 trains, 10 should be full

Hope this helps!

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
