Answer:

C. None of the above

Step-by-step explanation:

You can get the equivalent expression by simplifying the expression above.

  • 5+(-3)(6x-5)
  • 5+ (-18x+15)
  • 5-18x+15
  • -18x+20

-18x+20 is not the same with 18x-20, therefore A is not a correct answer.

For example, the value of x is 2.

  • -18(2) + 20 = ?                    
  • -36 + 20 = ?
  • -16
  • 18(2) - 20 =?
  • 36 - 20 = ?
  • 16

<em>-16 and 16 are not the same</em>

If Jeff washes his car in 6 minutes and bob washes the same car in 8 minutes. How long does it take both of them to wash the sam
Tatiana [17]

Answer:

3 3/7 or 24/7 mins

Step-by-step explanation:

Let total job = X

Jeff's rate = X/6

Bob's rate = X/8

Combined rate = X/6 + X/8

(4X × 3X)/24 = 7X/24

7X/24 = X/T

T = X ÷ (7X/24)

T = X × (24/7X)

T = 24/7 mins

Shortcut:

T = product of individual times/sum of individual times

T = (6×8)/(6+8)

T = 48/14

T = 24/7

T = 3 3/7 mins
