2. write an inequality for the sentence

a number n is postive


3. write an inequality for each situation

high fiber foods have at least 5g of fiber per serving. let f be the number of grams of fiber per serving of high fiber foods.

4. use a variable to write an inequality for each situation

well it has a picture of you know one of those things at theme parks and it says you must be 4ft. to ride and there is a little kid underneath that is a little shorter.

Answer 1

1. 1 yr = 52 weeks
y years = 52y

2. n > 0 or n >= 0 (>= means larger than or equal to)

3. f >= 5

Answer 2

1) There's 52 weeks in every year, so w = 52y

2) that means n is greater than 0, or n>0

3) So 1 serving (s) has at least 5 grams
2 servings have at least 10 grams
n servings have at least 5n grams
in other words, f is at least 5 times the number
of servings, or f>=5s
