480 is 100%
48 = 10%
480 = 100%
27.08 I used a money converter but at least it worked (I think)
-t(5t - 7) = -5
-1 -1
t(5t - 7) = 5
t(5t) - t(7) = 5
5t² - 7t = 5
5t² - 7t - 5 = 0
t = -(-7) ± √(-7)² - 4(5)(-5)
2(5)
t = 7 ± √49 - 4(-25)
10
t = 7 ± √49 + 100
10
t = 7 ± √149
10
t = 0.7 ± 0.1√149
Answer:
Explanation:
15 goes into 60, 4 times (1 fourth is equal to 25%).
15 goes into 75, 5 times (1 fifth is equal to 20%)
So 75 is one fifth more because it has a value of 15 more, and 60 is 1 fourth less than 75 because its value is more minuscule and less is more.
If you don't understand this was quite the challenge to explain.
