How do you write an inequality to model this situation a number exceeds 21

Answers

a number exceeds 21...it is greater then 21
x > 21
x>21
x represents a number. a number exceeds 21. x is greater than 21 therefore x(a number) exceeds 21.

Answer:

(x - 12)(x + 2)

Step-by-step explanation:

Given

x² - 10x - 24

Consider the factors of the constant term (- 24) which sum to give the coefficient of the x- term (- 10)

The factors are - 12 and + 2 , since

- 12 × + 2 = - 24 and - 12 + 2 = - 10 , thus

x² - 10x - 24 = (x - 12)(x + 2) ← in factored form

Charlene is knitting a baby blanket. She wants its width, w, to be at least half its length, l. She estimates that she has enough yarn to put fringe around the blanket, as long as the perimeter of the blanket is no more than 180 inches. The system of inequalities shown represents the width of the blanket in inches, w, and the length in inches, l.w ≥ 0.5l

2l + 2w ≤ 180

Answers

W > 0.5L

Perimeter:
2L + 2W < 180
2L + 2(0.5L) < 180
2L + 1L < 180
3L < 180
÷3       ÷3
  L < 60

Length should be less than or equal to 60 inches while width should be greater than or equal to 30 inches.

The length, L should be less than or equal to 60 inches whereas the width, W should be greater than or equal to 30 inches.

What are inequalities?

Inequalities refers to a system of two or more quantities in which one quantity is greater than or less than the other.

Based on the data given:

W > 0.5L

Perimeter of the blanket is given as:

2L + 2W < 180

2L + 2(0.5L) < 180

2L + 1L < 180

3L < 180

L < 60

Therefore, the length, L should be less than or equal to 60 inches whereas the width, W should be greater than or equal to 30 inches.
