What it wants you to do is to put it into a form where on the one side of the equation there is y and nothing else. for this, we need to get rid of the 0.9.

how do we do that?

we divide both sides of the equation by 0.9:

6.3/0.9=y

that's ugly, right? but if both denominator and nominator are decimal fractions of the same sort; we can multiply both by 10 and get rid of the point:

63/09=y
and...
\frac{63}{9} =7


so basically 7=y, or y=7

and this is the solution!

For a finite sequence of nonzero numbers, the number of variations in sign is defined as the number of pairs of consecutive term
elena55 [62]

Answer:

The no. of variations in sign is 3

Step-by-step explanation:

Variation in sign occurs when every single time a negative product is produced by a pair of consecutive terms.

Therefore, the determination of the number of changes in sign in the given sequence is must.

Therefore, we take the product of the pair of consecutive terms as:

1\times (-3) = - 3, variation in sign

(-3)\times 2 = - 6,  variation in sign

2\times 5 = 10,  no sign variation

5\times (- 4) = - 20,  variation in sign

- 4\times (-6) = 24, no sign variation

why can you write a subtraction problem as an addition problem?How do you write a subtraction problem as an addition problem?
-Dominant- [34]

You can write a subtraction problem as a division problem by subtracting one of the addends from the sum, then your other addend would be the answer.

Example :

5 + 6 = 11

11 - 5 = 6
