answering is c
Step-by-step explanation:
12×9=108
108+2=110
Answer:
47.5 degrees Farenheit
Step-by-step explanation:
the problem says temperature drops 1.8 deg F for every thousand feet. 3,000 ft of altitude will be achieved so that would to find the amount of deg the temperature will decrease we need to multiply 1.8 X 3, which is 5.4 degrees. subtract 5.4 degrees from 52.9 and you get 47.5 degrees at 3,000 ft of altitude
Answer:
m = -6
Step-by-step explanation:
3m= 5(m + 3)-3
Distribute
3m = 5m +15 -3
Combine like terms
3m = 5m +12
Subtract 5m
3m-5m = 5m+12-5m
-2m = 12
Divide by -2
-2m/-2 = 12/-2
m = -6
For this case what we have to take into account are the following properties:
1) In a division, same base, the exponents are subtracted.
2) Opposite signs are subtracted.
3) Equal signs are added and the sign of the major is left.
4) Power powers multiply.
