4x - 9 = 2x


Solve for x.

4x = 2x + 9

2x = 9

x = 4.5

We can plug 4.5 into the original equation to verify if it's correct.

4x - 9 = 2x

4(4.5) - 9 = 2(4.5)

18 - 9 = 9

The equation is true, and so x = 4.5

Find the next three terms in the sequence 625, 250, 100, 40...
pentagon [3]
Hi!

To solve this, let's divide

625/250 = 2.5

So is the pattern.. x/2.5 = x2/2.5 = x3/2.5...

We can test this theory by multiplying

100 x 2.5 = 250

Since 250 comes before 100 in the sequence then our theory is correct!

So to find the next numbers, divide:

40/2.5 = 16
16/2.5 = 6.4
6.4 = 2.56

The answer is C.

Hope this helps! :)
