Answer: D (I think)
Step-by-step explanation:
5 3/8 rounds to 5,
4 7/10 rounds to 5
Your estimated sum is 10
31/7 = 4 3/7.....3/7 is less then 1/2....so the closest integer is 4
It would be 3.01 because 40.00-40.00 is 0 then take away the other numbers 3.68- 0.67 is 3.01
X=any number
x is( greater than sign) (and then a line at the bottom of the greater or less than sign) x
it would be like this
x is greater than or equal to x
or
x is less than or equal to x
