Answer:
96 grams
Step-by-step explanation:
Each box has 5 strips with 12 capsules
5*12=60 each capsules contains 500 mg of medicine
60*500=3000mg of medicine per box
32*3000=96000mg total weight of the medicine or 96 grams
Let's translate the verbal language to algebraic language.
She rides to and from school 5 days per week, 6.25 miles each route => 5*2*6.25 miles = 62.5 miles.
She rides additioanly around the park 2.5 miles for each trip t => 2.5*t = 2.5t
Total miles of her rides per week: 62.5 miles + 2.5t
She wants to ride minimum 85 miles => 62.5 + 2.5t ≥ 85
Then, the situation is represented by this inequality:
2.5t + 62.5 ≥ 85
You can develop it and get to several equivalent inequalities, for example:
2.5t ≥ 85 - 62.5
2.5t ≥ 22.5
t ≥ 9
Any of the four forms are equivalent and a valid answer.

Answer:
x ≈ {-1.8, 0.5}
Step-by-step explanation:
I find a graphing calculator to be about the easiest way to solve these. It is convenient to put the equation into the form f(x) = 0. Here we can do that by subtracting 3x^2 from both sides.
9x^2 +8x -5 = 3x^2 . . . . . given
6x^2 +8x -5 = 0 . . . . . . . . subtract 3x^2
The solutions to this are the x-intercepts of the graph:
x = -1.8 or +0.5
