Joanna has a total of 7 rolls of coins worth of $23. She has of dimes worth $5 each and roll of nickels worth $2 each. How many rolls of each kind does she have?

Dang i wish i could , good luck (i’m bad at math)

First off , where's da graph ?

(6,1)(5,4)slope = (4 - 1) / (5 - 6) = 3/-1 = -3y = mx + bslope(m) = -3use either of ur , = 6 and y = 1now sub and find b, the y int1 = -3(6) + b1 = -18 + b1 + 18 = b19 = bso ur equation is : y = -3x + we need it in standard formy = -3x + 3x to both sides3x + y = 19 < == standard form
