Luba_88 [7]

Answer:

The correct answer is -30

Step-by-step explanation:

4(x+32)=8 basically you multiply 4 times the numbers that are in the parentesis which that will equals to 4x+128 because 4x1= 4x and 4x32 = 128. then you subtract 128 from 8 which equals to -120. you divide -120 by 4 which equals to -30.

Round 672,831 to the nearest ten thousand
Alik [6]
Well, you just have to take what I said before:

1=ones digit
3=tens digit
8=hundreds digit
2=thousands digit
7=ten thousands digit
6=ten thousands digit

So like previous answers, you just look at the digit after the one being asked

So look at the thousands place. 2,831 or 2,000 since all numbers after that digit is irrelevant

Is 2,000 or 2,831 over the halfway point to 10,000? The halfway point being 5,000

No, it is not so that means 2,831 is closer to 670,000 rather than 680,000

Answer: 672,831 rounded to the nearest ten thousand IS 670,000
