Answer:
20%
Step-by-step explanation:
Going of a guess, if you divide 20 by 100, then multiply .2 and 75 you get 15 and 75 - 15 is 60.
Tan⁴x - sec⁴x = 1 - 2sec²x
tan²x = sec²x - 1
tan⁴x - sec⁴x = 1 - 2sec²x
(tan²x)² - sec⁴x = 1 - 2sec²x
(sec²x - 1)² - sec⁴x = 1 - 2sec²x
(sec²x)² - 2 * sec²x + 1 - sec⁴x = 1 - 2sec²x
sec⁴x - 2 sec²x + 1 - sec⁴x = 1 - 2sec²x
sec⁴x can be cancelled:
- 2 sec²x + 1 = 1 - 2sec²x
1 - 2sec²x = 1 - 2sec²x

Answer:
8.75n = 61.25
Step-by-step explanation:
We multiply n, number or hours, times how much he makes per hour.
Therefore, it is 8.75n = 61.25
Hope this helps :)
Answer:
220
Step-by-step explanation:
We have given that Colin scored 25 and Brian scored x ( x-unknown)
Since we know that Brian scored 170 more than Colin, Brian scored:
x = 25 + 170 = 195
Now we know that Colin scored 25 and Brian scored 195.
They together scored
25 + 195 = 220
