Step-by-step explanation:

Two angles are called supplementary when their measures add up to 180 degrees.

<ADB + <BDC = 180°

IT'S seen that BOTH ADB and BDC are 90 degrees

90+90= 180

Nancy’s nut store sells peanuts for $2 per pound and cashews for $10 per pound. The store sells a peanut - cashew mixture for $7
Gelneren [198K]

9514 1404 393

Answer:

  • 25 pounds cashews
  • 15 pounds peanuts

Step-by-step explanation:

Let c represent the number of pounds of cashews in the mix. Then 40-c is the number of pounds of peanuts. The total cost of the mix is ...

  10c +2(40 -c) = 7(40)

  8c +80 = 280 . . . . simplify

  c +10 = 35 . . . . . . . divide by 8

  c = 25 . . . . . . . . . . subtract 10

  40-c = 40-25 = 15 . . . . pounds of peanuts

25 pounds of cashews and 15 pounds of peanuts should be used in the mix.
