Answer:
Step-by-step explanation:
Multiplier: -175/3 Decrease: 23⅓ %
Step-by-step explanation: 75 = 250 - 3(d) d = -175/3 Y = 250 - (175/3)m
Where m is the no.
of months Y is the new value
(175/3)/250 × 100 = 70/3 %
Or 23⅓ %
(6x+9y=78) - (6x+4y=38) = (5y=40) = y=8
(2x+3(8)=26) = (2x+24=26) = (2x=2) = x=2
