868 is about 870, and 28 is about 30, so your expression would be 870 divided by 30 which would be 29 and the actual answer is 31, so your estimate would be close to your actual answer.
Answer:
i think ur right or letter b butu not c
Step-by-step explanation:
No.
Since w = 8, you must replace the variable with the number associated to it.
So, it would be 5 + 8 = 58
5 + 8 is not equal to 58, it is equal to 13.
If you wanted to find out what w was, simply subtract 5 on both sides.
w = 58 - 5
C.
9987 × 1.04 = 10386.48
10386.48 - 1950 = 8436.48
8436.48 × .25 = 6327.36
