Answer:

20 pounds of peanuts and 80 pounds of cashews.

Step-by-step explanation:

A nut wholesaler sells a mix of peanuts and cashews.

We need to find the amount of peanuts and cashews should be used to make 100 pounds of the mix.

Let x pounds of peanuts y pounds of cashews are mixed.

x+y=100                .... (1)

He charges $2.80 per pound for peanuts and $5.30 per pound for cashews. If the mix is to sell for $4.80 per pound.

2.80x+5.30y=4.80\times 100

2.80x+5.30y=480          .... (2)

From (1) we get

x=100-y             .... (3)

Substitute this value in equation (2).

2.80(100-y)+5.30y=480

280-2.80y+5.30y=480

2.50y=480-280

2.50y=200

Divide both sides by 2.50.

y=80

Substitute y=80 in equation (3).

x=100-80=20

Therefore, 20 pounds of peanuts and 80 pounds of cashews should be used to make 100 pounds of the mix.

X~4y=11 , 5x~7y=~10 system of equation using elimination to solve
tino4ka555 [31]
1x + 4y = 11 ⇒ 5x + 20y = 55
5x - 7y = -10 ⇒ <u>5x -   7y = -10</u>
                                 <u>27y</u> = <u>65</u>
                                  27     27
                                     y = 2¹¹/₂₇ 
                     x + 4(2¹¹/₂₇) = 11
                         x + 8²²/₂₇ = 11
                         <u>    - 8²²/₂₇  - 8²²/₂₇
</u>                                     x = 2⁵/₂₇
                              (x, y) = (2⁵/₂₇, 2¹¹/₂₇)
