Answer:
Z = 20
Step-by-step explanation:
3 x 20 = 60
60 - 12 = 48
3(m-2)=5(m-4)
3m-6=5m-20
3m-5m=-20+6
-2m=-14
-m=-7
m=7
I hope this is what you need..
10/3 = x / 12.....$ 10 to 3 lbs = $ x to 12 lbs
cross multiply
3x = 120
x = 120/3
x = 40....so it is gonna cost Sylvia $ 40 for the meat.
she plans on making 50 burgers......40 ($ worth of meat) / 50 (burgers) =
0.8....so for each burger, the meat will cost 0.80 or 80 cents <==
