Answer:

The distance driven by the McAlister family car in one year, to the nearest thousand, is 16,000 miles.

When you are to round something off to the nearest thousand, you should look at the hundred figure.

If the hundred figure is 5 and above, you round the entire number to the nearest thousand that is higher than the number. If the hundred number is 0 - 4, the entire number should be rounded down to the lower thousand.

The hundred number here is "6" which means that you have to round up. The thousand figure that is nearest and higher is 6,000 so the entire number becomes 16,000.

In conclusion, the distance of 15,680 miles rounded to the nearest thousand is 16,000 miles.

Answer: The original figure is 15680 which to the nearest thousand is 16000 because the 680 rounded to a thousand gets up to 1000

Simplify 5(9+3) - 4x3 =

Answer:

48

Step-by-step explanation:

5(9) + 5(3) - 4(3)

45+15-12

60-12

=48

Answer:

5(9+3) - 4x3 = 48

Step-by-step explanation:

- First, we start off with Distributive Property. 5 times 9 which is 45 and 5 times 3 which is 15. Now we have 45 + 15.
- Next, multiply 4 by 3 which is 12. Now we have 45 + 15 -12.
- Lastly, we have to add together 45 and 15 which gives 60 but you have to subtract 12 from it which will give an answer of 48.

5(9+3) - 4x3 =

45 + 15 - 12 = 48

I hope this helps. :)
