Astack of $20, $50 and $100 bill was retrieved as part of a police investigation. there were 47 more $50 bills and $100 bills. also, the number $20 bill was three times the number of $100 bill. if the total volume of money was $7810 find the number of each type of bill

Step-by-step explanation:

$100 bill = x

$50 bill = x+47  $20 bill =3x                                                                                                  100x+50(x+47)+20*3x=7810                                                                                                  

100x+50x+2350+60x=7810

210x+2350=7810

210x=7810-2350

210x=5460

/210

x=26

.$100 bill = x =26

$50 bill = x+47=73

$20 bill = 3x=78                                                                                                               please give brainliest

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y
