Jeremy is looking for two different lawncare companies to weed and mulch his flower beds. greenscape charges $100 for the mulch plus $12 per hr for labor. d& j landscape charges $23 per hr for the job including the mulch. what is the minimum number of hours the job could be for d& j landscape to have the better deal?

Let x represent the number of hours and y represent the total cost

Greenscape equation: y = 12x + 100

D&J Landscape equation: y = 23x

Use substitution to find out how many hours for the cost to be the same.

23x = 12x + 100

11x = 100

x = ≈ 9.1 hours

D&J Landscape is a better deal when the job takes less than 9.1 hours.

answer: a.   one is a factor of every whole number since every number is divisible by itself.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
