Answer:

63.96

Step-by-step explanation:

You multiply the first number (0.2) by 12.3

Then, multiply the second number (5) by 12.3

> 12.3 x 5 = 61.50

After that, ADD.

61.50 + 2.46 = 63.96

Your answer should be 63.96

Answer:

C.47

Step-by-step explanation:

You want to plug in all the numbers which gives you 3^3+2(8)- -4. You do 3*3*3 which gives you 27. You then do 2(8) which gives you 16. So your problem now is 27+16- -4. 27+16 is 43 and being you are subtracting a negative, it turns to a positive. So your answer ends up being 47.

C is 47 hope this helps
