Ellen had 25 hair clips. 7 of them were blue and the rest were purple. What percent of hair clips were purple?
To find out how many hair clips are purple, we can subtract 7 from 25 to see how many hair clips are purple. 25 - 7 = 18 so we now know that 18 hair clips are purple.
The fraction represents the number of purple hair clips Ellen has out of all the hair clips together.
To find what percent of the hair clips are purple, we can turn this into a fraction.
18 ÷ 25 = 0.72
0.72 × 100 = 72%
Therefore, 72% of Ellen's hair clips were purple.
Answer: x= 41
Explanation: Angles 1 and 2 have to equal 180° since they are supplementary. So you put 3x+2x-25=180, you then add like terms. 5x-25=180 Then you have to isolate x, so you add 25 to both sides of the equation. 5x=205, then you divide both sides by 5. So your answer is x=41.
You can check to make sure by plugging in x for 41 .
Hope this helps!
