Answer:
50 i think
Step-by-step explanation:
Yes this is equal because 3v+v is 4v and if you divide 12v by 3 you also get 4v
I'm not sure about the answer, but this is how I would do it, since 15% and $150 are the same based on the question. do let me know if it's right! :)
Answer:
138 fluiere, 158 ocarine, 184 viori
Step-by-step explanation:
given:
(1) fluiere + ocarine +viori = 480
(2) fluiere + ocarine =296
(3) ocarine + viori =342
din ecuatia (3) avem: viori= 342-ocarine
din ecuatia(2) avem : fluiere= 296-ocarine
in ecuatia (1) inlocuieste ce ai gasit ca sa fie o ecuatie doar cu necunoscuta ocarine: fluiere + ocarine +viori = 480
296-ocarine +ocarine+ 342-ocarine =480
296+342-480 = ocarine =158
viori = 342-158 = 184
fluiere = 296-158 = 138
