Answer:
D α H
k = D/H
k = 3.50
Step-by-step explanation:
Amount paid, D is directly proportional to the number of hotdogs, H
D = $3.50 per hot dog
D = $3.50 is directly proportional to 1 hotdog
Hence,
D α H
D = kH
k = proportionality constant
H = 1
3.50 = k
k = 3.50
k = D/H
Answer:
1032xy + 72
Step-by-step explanation:
(3x3y0x-2)4(y2x-45xy-8)3=
(0-2)×4(2xy-45xy-3)×3=
-2×4(2xy-45xy-3)×3=
-2×4(-43xy-3)×3=
-24(-43xy-3)
1032xy+72
Well.. There's 3y-2=y+4 right?
Add 2 and you get 3y=y+6
Minus y- you get 2y=6
Divide it at 2 and you get y=3.
Sorry for the explanation but I'm from another country and this is the best I can
