If 30% of his collection is 12 cars, then we can use the fraction
30/12=100/x
x=40
Answer:
A=80
B=31
C=64
Step-by-step explanation:
A, 69, and b will equal 180 since it forms a straight line
A+69+b=180
to solve for A we subtract 53+47 from 180 and get 80
80+69+b=180
to get B we subtract 80+69 from 180 and get 31
to get c we add 85+b and subtract it from 180 getting c=64
Well heres what to do
300 residents 5yrs
divde 300 by 5= you get 60 a yr
62+92 is 154. 180- 154 is 26
