8. Explain Why 30+1 = 6 Is The Same As 30 -/-/--/-X-X = 0. What Isthe Value Of X In This Example?

Answers

Answer 1

Answer:

5

Step-by-step explanation:

5 because of two ways one you could do 6*what is 30. Or you could do repeated addition 30=5+5+5+5+5+5. But when you do 30=5-5-5-5-5-5. You are doing repeated subtraction which is equivalent to 30-5*6= 0.

Hope this helps more than the link! :)

Answer 2
the answer if 5 because because you can first divide 30 by 6 then get 5, and you can check that answer by subtracting 6 from 30, 5 times -hope this helps

Convert 9432000 Milliliters to Liters. Show ALL work and don't forgot the units.

Answers

Answer: 9,432 L

To convert 9,432,000, divide by 1,000. Let's explain before we divide.

Look at the zeros in 9,432,000, then look at 1,000. What do they have in common? Zeros. Both numbers have 3 zeros. But what would happen if we divide it by 1,000? Let's figure it out now.

1. Divide 9,432,000 by 1,000.

9,432,000 ÷ 1,000 = 9,432

Notice how the zeros were gone when we divided it by 1,000, because we're reducing it by 1,000.

Hence, 9,432 L is the answer.
