Find the solution to the system of equations below (you can do this by substitution or elimination).
rewona [7]

Step-by-step explanation:

y=6+4x, as equation (iii)

=> -5x-(6+4x)=21

=> -5x-6-4x=21

=> -5x-4x-6=21

=> -9x-6=21

=> -9x=21+6

=> -9x=27

x= -3, by dividing both sides by -9

So, by inserting x in the first equation,

=> -4(-3)+y=6

=> 12+y=6

=> y=6-12

=> y= -6.

Therefore, x= -3 and y= -6

Two teams are distributing information booklets. Team A distributes 60% more boxes of booklets than Team B, but each box of Team
Alexxx [7]

Answer:

  C.  4,100

Step-by-step explanation:

"60% more" is represented by a multiplier of 1 + 0.60 = 1.60.

"60% fewer" is represented by a multiplier of 1 - 0.60 = 0.40.

__

Let b represent the number of booklets distributed by Team B. Then the number distributed by Team A is ...

  1.60 × (0.40b) . . . . 60% more boxes, each with 60% fewer booklets

  = 0.64b

Then the total distributed by both teams is ...

  b + 0.64b = 1.64b = (164/100)b = (41/25)b

The only answer choice that is a multiple of 41 is ...

  4,100 . . . choice C

__

For 4100 to be the number of booklets distributed by both teams, Team B will have distributed 2500 booklets, and Team A will have distributed 1600 booklets. Team A might have distributed 160 boxes of 100 booklets, while Team B might have distributed 100 boxes of 250 booklets.

lubasha [3.4K]

$4.75

Step-by-step explanation:

As the price per pound is a one-to-one ratio, one could just simply multiply by using: 0.7 lbs * ($6.79 / 1 lb) = $4.75/1 = $4.75
