Step-by-step explanation: Divide 496 by 218.
The proportion that could be used to solve for the variable is
; h = 7.5 ⇒ answer b
Step-by-step explanation:
A proportional relationship: one variable is always a constant value times the other, that constant is called the constant of proportionality
- y = k x is the equation of the proportional relationship
- We can write the proportional relationship in the form
The number of walls and the number of hours are increased or decreased together
∴ The number of walls and the number of hours are proportion
∵ 16 walls in 40 hours
∵ 3 walls in h hours
- By using the second rule above
∴
The proportion that could be used to solve for the variable is
Let us solve it to find h
∵
- By using cross multiplication
∴ 16 × h = 3 × 40
∴ 16 h = 120
- Divide both sides by 16
∴ h = 7.5
The value of h is 7.5 hours

0.3 is less than 0.39 because 0.3 is equivalent to 0.30
Answer: 9x + 4x²
Explanation:
1) Length = 14x - 3x² + 2y
2) Width = 5x - 7x² + 7y
3) Length - width = [14x - 3x² + 2y] - [5x - 7x² + 7y]
4) Calculate:
i) Distribute the negative sign in front of the second polynomial:
14x - 3x² + 2y - 5x + 7x² - 2y
ii) Combine like terms:
9x + 4x²
5) Answer: 9x + 4x²
