Answer:
Either 43 or 44, depemding on if you round up.
A means 7 10 times so it like 7x10 same with g 96x10
Answer:
k divided by three plus sixteen
Work in rates per hour. These rates can then be added to form an equation
1/13 + 1/10 = 1/x where x is the time for both working together
multiply thru by 130x:-
10 x+ 13 x = 130
x = 130/23 = 5.65 hours or about 6 hours 39 minutes
Let:
T1 = temperature at 6:00 AM
T2 = temperature during the day
T3 = Temperature by early evening
The temperature at 6:00 AM was -8. so:

The temperature rise 5 during the day:

and then fell 3 by early evening, therefore:
