Combining the numbers, we get 3w+12=5
3w=-7
w=-7/3
Answer:
-12.8%
Step-by-step explanation:
To calculate the percent decrease, we:
- Find the difference between the new value and the original
- Divide the number by the original
- Multiply by 100 and the % symbol.
The population of the town originally had 25,000. 3,200 people moved away. This means that the new population is 21,800.
- 21,800-25,000=-3,200
- -3,200/25,000=-0.128
- -0.128(100)=-12.8%
The towns population decreased by 12.8%.
Flip the x and y like in the coordinate plane x,y not y,x
True.....I am not really good at explaining, but I would try. for any fraction , if it is multiplied by it inverse it equals to one because they end up crossing out. example: 3/4 ×4/3=1
6/23×23/6=1
