will likes two brands of healthy breakfast cereal. in superfiber cereal, there are 5 grams of fiber in one cup. in fiber oats cereal, there are 4 grams of fiber in one cup. let x represent the number of cups of superfiber will ate this week and let y represent the number cups of fiber oats he ate this week. which inequality represents the situation if the cereal will ate this week contained at least 30 grams of fiber? a)5x + 4y ≥ 30b)4x + 5y ≥ 30c)4x + 5y ≤ 30

Let x  represent the number of cups of Superfiber Will ate this week and let y  represent the number cups of Fiber Oats he ate this week.

1. If in Superfiber cereal, there are 5 grams of fiber in one cup, then in x cups there are grams of fiber.

2. If in Fiber Oats cereal, there are 4 grams of fiber in one cup, then in y cups there are grams of fiber.

3. The total amount of fiber Will ate is grams.

4. This week Will ate at least 30 grams of fiber. Then

correct choice is A.

the inequality is:  a)5x + 4y ≥ 30

Step-by-step explanation:

Hi, to solve this problem we have to analyze the information given:

So, the cereal Will ate this week contained at least 30 grams of fiber. At least means more or equal ( ≤ 30 ).

If each cup of Superfiber cup has  5 grams of fiber ⇒ 5x

If each cup of Fiber Oats cup has  4 grams of fiber ⇒ 5y

Finally, the inequality is:

a)5x + 4y ≥ 30

70,000 + 6,000 + 800 + 30

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
