Answer:
5
Step-by-step explanation:
this is basic algebra so it's important to understand this concept now. you need to combine like terms so 3x-6=9 becomes 3x=15 (you add the 6 to add like terms). You then divide the 3 from 3x on both sides to get x=5
Answer:

Step-by-step explanation:
we know that
![\°C=\frac{5}{9}[\°F-32]](https://tex.z-dn.net/?f=%5C%C2%B0C%3D%5Cfrac%7B5%7D%7B9%7D%5B%5C%C2%B0F-32%5D)
For 
substitute in the formula and solve for F
![94=\frac{5}{9}[F-32]](https://tex.z-dn.net/?f=94%3D%5Cfrac%7B5%7D%7B9%7D%5BF-32%5D)
![(\frac{9}{5})*94=[F-32]](https://tex.z-dn.net/?f=%28%5Cfrac%7B9%7D%7B5%7D%29%2A94%3D%5BF-32%5D)


Answer:
62.7
Step-by-step explanation:
You would first look at the tens place numbers; 10 and 30. and add them together making 40. after that you'd take the ones places and add them together; 7 and 8. add those together and you'd get 15. to finish you just need to add the two numbers together 40 and 15.
