If you divide both sides of your inequality by five, you see that k must be less than 9

k < 9 that is equivalent.

You can make another equivalent inequality by multiplying both sides by 3.

3k < 27

What number is equivalent to: 4 x 1,000,000,000 + 5 x 1,000,000 + 9 x 10,000 + 8 x 100 + 7 x 1?

valina [46]

Answer:

4,005,090,807

Step-by-step explanation:

4 x 1,000,000,000 + 5 x 1,000,000 + 9 x 10,000 + 8 x 100 + 7 x 1

4 * 1,000,000,000 = 4,000,000,000

5 * 1,000,000 = 5,000,000

9 * 10,000 = 90,000

8 * 100 = 800

7 * 1 = 7

Add it all together and you get 4,005,090,807

I hope this helped. Sorry if you get this wrong.

Do ratios 15:5 and 6:2 form a proportion?

mrs_skeptik [129]

For two ratios to form a proportion they have to be equal.

To see if two ratios are equal we express them in their simplest form.

In this case we notice that in the first ratio both numbers are multiples of five, then:

$15\colon5=3\colon1$

In the second case we notice that both numbers are multiples of 2, then:

$6\colon2=3\colon1$

Since both ratios can be simplified to the same final ratio, they form a proportion.
