Abox of cereal contains 340 grams of carbon hydrates if there are 12 servings about how many grams are there in one serving show how you estimated explain why your answer is reasonable

30 grams

Step-by-step explanation:

To estimate using mental math, make 340 grams become 360 grams (because 12 fits into 36 perfectly). Now if you divide 360 by 12 you get a whole number: 30. Therefore you can estimate that there are about 30 grams of carbs in a serving.

The answer is reasonable because you changed 340 to a number that can easily work with 12 and is the closest (closer than 240), so you would get a not far-off answer.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

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.
