7x - 8 (8 less than 7x a #)
Answer:
the number of children has red or brown hair is
.
Step-by-step explanation:
We have been given that in Marci's family there are total 6 children.
Out of 6 children
Number of children have blonde hair = ![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
Number of children have red hair = ![\frac{1}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B6%7D)
Number of children have brown hair = ![\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D)
Since, we have to find the fraction of children has red or brown hair=![\frac{1}{6}+\frac{1}{2}=\frac{4}{6}=\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B6%7D%2B%5Cfrac%7B1%7D%7B2%7D%3D%5Cfrac%7B4%7D%7B6%7D%3D%5Cfrac%7B2%7D%7B3%7D)
Hence, the number of children has red or brown hair is ![\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D)
