Answer:
She's been charged 84 dollars
Step-by-step explanation:
Let's call each month m
if every month it deducts 7 dollars, then to find how much has been charged after a year, we do
-7 * 12 = -84
The number of required shelves is 5
You have to find the HCF of 45, 105, and 75.
B a = 180 -77-60
The angles add to 180 degrees since they form a straight line
77+ 60+a = 180
a = 180 -77-60
4/5 * 3 = 12/5
20 * 3 = 1 hour = 60 min
