39.99+.10t=19.99+.20t
Now -19.99 from both sides to get 19.00+.10=.20t
Now simplify 19+.10 to 19.10=.20t
Lastly divide both sides by .20 to get t=95.5 :)
Answer: y=-9/8x+7
Step-by-step explanation:
1/3+9=(9 1/3)
8-3= (5)
9*5=45 add the 1/3 back in
45 1/3 for the fraction take 45*3=135+1= 136/3
136/3 is the answer
It would be 5 hours and 17 minutes
