Write and solve an inequality to determine how many hours she must train if she burns an average of 750 calories per hour and eats a total of 8000 calories

The required inequality:

She must train at least 8 hours.

Step-by-step explanation:

Consider the provided information.

An athlete wants to maintain a net caloric intake of no more than 2,000 calories for the day.

We need to determine how many hours she must train if she burns an average of 750 calories per hour and eats a total of 8000 calories.

Let the number of hours is h.

She burns an average of 750 calories per hour so for h hours she will burns 750h calories.

She want to maintain no more than 2,000 and she eats a total of 8000 calories.

Therefore, the required inequality:

Now solve the inequality as:

Hence, she must train at least 8 hours.

answer: about 22.67

step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
