The answer is -3/8 hope this helps
(x - 6) * 2
I'm assuming this is the expression that you typed out, if it isn't, please let me know in the comments :)
Use the distributive property:
= 2(x) - 2(6)
Multiply and simplify
= 2x - 12
This should be the expression that is equivalent to the original. Let me know if you need any clarifications, thanks!
Total no. of births = 2000
Births of girls = 64
Birth% of girls
![= \frac{64}{2000} \times 100](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B64%7D%7B2000%7D%20%20%5Ctimes%20100)
![= \frac{64}{20}](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B64%7D%7B20%7D%20)
![= \frac{6.4}{2}](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B6.4%7D%7B2%7D%20)
![= 3.2\%](https://tex.z-dn.net/?f=%20%3D%203.2%5C%25)
Hence, the number of girls are significantly low.
