In front end estimation you use the first two numbers to round
4. 6.14 -> 6.00
9.38-> 9.00
=15.00
5. 39.65-> 40.00
25.84-> 30.00
=70.00
6. 9.71 -> 10.00
3.94-> 4.00
=14.00
16.2 + 16.2 + 16.2 + 16.2
So your answer is 64.8
Answer:
61+69+45= 175 years added together
Step-by-step explanation:
Emily is 61
Colin is 61+8=69
and Dan is 61-16 which is 45, so when you add them together you get 175 years
Answer:
B) -1 and D) 1
Step-by-step explanation:
We want to find the solution to

Which means that we want to find the values of x at which the two functions f(x) and g(x) are equal.
In order to do that, we have to look at the table, and see at which values of x the two functions have the same value.
We observe that the only two values at which this occurs are:
at
, where both functions are equal to 
at
, where both functions are equal to 
Answer:
(-3, -5), because the point satisfies both equations.
