250 mg / 100 mg = 2.5 ml
5 ml / 2.5 ml = 2
1/2 teaspoon
So basically x and y are 4 because the hypotenuse of a 45 45 90 triangle is x square root of four. both legs of the triangle are congruent, given taht it’s a 454590
1/2b+2≤8
1/2b≤6
b≤12
Any number less than or equal to 12 can solve the equation.
