146, 74, 38, 20, ? what would the next number be in this sequence?

1 answer:

3 0

Looking at the numbers, we can see that the differences are 72, 36, and 18. Notice that they are each factors of the next by the same constant 2.

18 * 2 = 36
36 * 2 = 72

There, it means that 18/2 will be subtracted from 20.

20 - 18/2
= 20 - 9
= 11

The next number in the sequence would be 11. Hope this helps!

Convert the decimal 0.8 to a fraction in the lowest terms

AnnZ [28]

0.8 = 8 tenths.

1 tenth = 0.1 = 1/10
8 tenths = 0.8 = 8/10.

8/10 divide both the numerator and denominator by a common factor that is the greatest. In this case is 2.

After doing so, the result should be 4/5.

What is the horizontal distance between (−5/3, -2) and (4, -2)?

Nataly [62]

Answer:

-2?

Step-by-step explanation:

use y2-y1 over x2-x1 to find the answer. So you would do -2--5/3 over 4--2. The two negitives turn into a positive. SO it is now -2+5/3 over 4+2. -2+5/3= -1/3 over 4+2=6 it is now -1/3/6 which equals -2. So I think the answer is -2.<u> I do not know if you should trust me on this but I tried. </u>
