Answer:
60
Showing-MY-Work:
4 months is 1/3 of a year. (12 months = 1 year)
Since know that they became 20, after 4 years, then we just times 20 by 3.
Because 3 times 4 = 12
20 times 3 = answer you're looking for
121
Step-by-step explanation:
180 - (56 + 65) = 59
180 - 59 = 121
g(10) = (10^2-8)/(10+4)= (100 - 8)/14 = 92/14 = 48/7 or 6 6/7
