You haven't shared the list of expressions from which you are to choose an answer.
However: you can perform this estimation yourself as follows:
Round off both -21.87 and 4.79. -21.87 goes to -22 and 4.79 to 5. Then
a good estimate of -21.87 divided by 4.79 would be -22/5, or -4.4.
Answer:
see below (I hope this makes sense!)
Step-by-step explanation:
Constants, as the name suggest, stay constant, meaning that their value never changes. For example, 2 will always be 2 and 9.4 will always be 9.4. On the other hand, the values of variables can change. Take, for example, the variable 2x. When x = 1, 2x = 2 and when x =2, 2x = 4 so the value of 2x can change depending on what x is. You can't combine constants and variables because they are not like terms, basically, one can change and the other can't and you cannot combine terms that are not like each other.
Answer:
It rose 17 meters
Step-by-step explanation:
163m is the depth of when it dove so if you take 163-68 then you get the original depth of 95 then take 95 - 78 to get 17 meters and thats your answer hoped i helped! :D good luck and i hope you do better
9 students had at least one brother and no sisters.
The constant of the function is 6.
A constant is a fixed number whose value does not change. 6 is the only number that is not affected in any way.
