Answer:
=
Step-by-step explanation:
(5ab-4a-8)-(9ab-5)
Ok just remember that the minus sign before the (9ab-5) is like a minus 1 so it changes the sign inside the bracket...
>>5ab-4a-8-9ab+5
>>-4ab-4a-3
I'm guessing you just have to leave it like that unless there are other parts to the question or whatever but that's that simplified as far as it can be!
Answer:
34,000
179,400
39,900
Step-by-step explanation:
In the number 33,762, the 3 is in the thousands place, so we look to the number behind it. If it is less than 5, we round down, and if it is more than 5 we round up.
Since 7 is more than 5, we round up, so our rounded number would be
34,000
Let’s use this logic for the rest of these numbers
179,406
4 is in the hundreds
Previous number in 0 which is less than 5, so it rounds down
179,400
39,994
9 is in the tens place
Previous number is 4 which is less than 5, so it rounds down
39,990
