Answer:
B
Step-by-step explanation:
A. 37 isn't a number sentence
B. 49 + (-12) = 49-12. They're the same thing because 49 minus 12 can also be written as 49 plus negative 12
C. 49 + 12 doesn't equal 49-12
D. 12- 49 = -37 which isn't equivalent to 49-12.
Hope this helps!!!
Answer:
70.6
Step-by-step explanation:
The mean is the average of a set of numbers.
To find it, add up all the terms and divide it by the number of terms.
70 + 67 + 79 + 66 + 64 + 80 + 64 + 75 = 565
565 / 8 = 70.625
Rounding this to the nearest tenth, we get an answer of 70.6
