Answer:

x < 2

Step-by-step explanation:

→ Expand out brackets

-1 - 6 - 18x > -39 - 2x

→ Simplify

- 7 -18x > -39 - 2x

→ Add -7 to both sides

-18x > -32 - 2x

→ Add -2x to both sides

-16x > -32

→ Solve for x

x < 2

Steve bought a total of 6 packages of pens, and each package contained either 3 or 7 pens. If exactly 4 of the packages Steve bo
dusya [7]
The answer is D, 34

If 4 of the packages contain 7 pens, that means there, 28 pens are total.

Because they contained either 3 or 7 pens, I would assume the remaining 2 packages of 6 total that Steve had bought would have to have 3 pens. 

3*2 is equal to 6

28 + 6 = 34

Isaac shoveled 9 of his neighbors' driveways after a snow storm. He charged $25 for a short driveway and $45 for a long driveway
e-lub [12.9K]

Answer:

y($) =  405- 20x

Step-by-step explanation:

Number of short driveways = x

Number of long driveways = 9-x

Fee per long driveway = $45

Fee per short driveway= $25

Total amount = y

y ($) =  25x + 45 (9-x)

      =  25x  + 405 -45x

      = 405- 20x
