1 answer:
Nikitich [7]4 years ago
4 0

Answer:

D

Step-by-step explanation:

A is not, because 2-5x = -5x+2

(nothing has changed but the order)

B is not, because 3-5+2x = 2x-2

because 3-5 = -2. so -2+2x can be rewritten as 2x-2.

C is not, because 5x-2x = 3x

because you combine like terms, and 5-2 is 3

D <em>i</em><em>s</em><em>,</em> because 2x-2+3x = 5x-2

because you combine like terms (2x+3x=5x) and -2 is left.

If there is a maximum of 4,000 hours of labor available per month and 300 ping-pong balls (x1) or 125 wiffle balls (x2) can be p
andrey2020 [161]

Answer:

b. 300x1 + 125x2 < = 4,000

Step-by-step explanation:

Maximum of 4,000 hours

This means that the the total amount of labor has to be of at most 4,000, that is:

T \leq 4000

300 ping-pong balls (x1) or 125 wiffle balls (x2) can be produced per hour of labor

The total amount of labor is:

T = 300x1 + 125x2

Uniting the two equations:

T \leq 4000

300x1 + 125x2 \leq 4000

And thus the correct answer is given by option b.

mario walks his dog once every 8 days in the park, while todd walks his dog once every 14 days. today, both mario and todd walke
notsponge [240]
Assuming both Mario and Todd just walked today.

Mario is every 8 days

Todd is every 14 days.

The days that will coincide is the Least Common Multiple (LCM) of 8 and 14

  2 /    8    14
  2  /    4      7
  2  /     2    7
  7 /     1     7
    /      1     1


The LCM =  2 * 2* 2* 7 =  56

The will both walk together in the next 56 days.
