27 and 200/3

Step-by-step explanation:

Let the no of orange pop cups be x,

Then,

2:3=18:x

2/3=18/x

2/3x=18

x=18/2/3

x=18×3/2

x=27

For no 2 everything is same except the rhs

2/3=x/100

2/3×100=x

200/3=x

Therefore 200/3 cups are needed to make 100 pineapple cups.

345

step-by-step explanation:

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.
