Which of the following is the most reasonable estimate for the number of calories in one serving of milk

The number of calories in one serving of milk should be 86 Calories/serving. It means between 80 and 90.

Step-by-step explanation:

Let's suppose a milk composition similar to that of the attached image. We need to estimate the most reasonable of the number of calories in one serving of milk.

According to the information presented in the milk: The whole package will have 5 servings, and the whole package will aport 430 Calories.

Now, we need to calculate the number of calories per serving (C1), it is thus necessary to divide total calories (C) by the number of servings (S).

C1 = C/S

C1 = 430 calories / (5 servings)

C1 = 86 Calories/serving.

Finally, we can conclude that the number of calories in one serving of milk should be 86 Calories/serving. It means between 80 and 90.

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
