Solution in an attachment.
x = -4; y = -2; z = 4
Remark
This is an excellent question. Estimation is a powerful skill to have. People should always shop using estimates. Try it to see what happens.
x = 11.7 which rounds up to which we will call x1 and that is 12
y = 6.03 which round down to 6 which we will call y1 and that is 6
Now x - y = 5.67
If you do the rounded subtraction x1 - y1 = 12 - 6 = 6
The estimate is not zero. D is not correct.
There is enough information E is not the answer.
B is wrong, her estimate is larger than x - y
C is wrong the two subtractions are not equal.
A is correct and always will be no matter what numbers are chosen
A <<<< Answer
Answer: D: 23.99
Step-by-step explanation:
What number is 0.01 less than 24?
The number 0.01 less than 24 is equal to 24 - 0.01;
24 - 0.01 = 23.99
D: 23.99
