Answer:
Step-by-step explanation:
"The total number of dollars in fives and tens" tells you that these denominations are being added together. Because a five dollar bill is worth $5 and a ten dollar bill is worth $10, then the number of $5 bills is represented by 5f and a the number of $10 bills is represented by 10t. Therefore,
T = 5f + 10t
4 I think because you subtract all since it's 60 min
There are 7,920 minutes in 5.5 days
60minutes in an hour
24hours in a day
60 times 24 times 5.5 = 7,920
Use a ruler for this problem. Take a picture of the measurement & then I could help you.
