Answer:
C and D
Step-by-step explanation:
I'm guessing the 3 in A and B are exponents, only equations with an highest exponent of 1 is linear
The estimated sum of 196 and 482 is 700.
We do estimates when we do mental calculation. We relate the number to the nearest number that can easily be computed mentally.
196 is near 200 so we round it up to 200
482 is near 500 so we round it up to 500
Thus, 200 + 500 = 700.
700 is the estimated sum.
10. 6.8 this is the nearest tenth
13. 3.7 this is the nearest tenth
16. 6.7 this is the nearest tenth
8.6 first number after the decimal is the tenths place then the second number after the decimal is the hundredths
