Time = Distance ÷ Speed
= 198 km ÷ 36 km/h
= 5.5 h
Monday = 16 pages
Tuesday = 16 + (50% of 16) = 16 + (0.5 x16) = 24 pages
Wednesday = 24 + (50% of 24) = 24 + (0.5 x 24) = 36 pages
Thursday = 36 + (50% of 36) = 24 + (0.5 x 36) = 54 pages.
Total pages = 16 + 24 + 36 + 54 = 130 pages
Pages Greg read per day = 130 ÷ 5 = 26
Answer: Greg read 26 pages per day.
54:36 is your answer.

Answer: 25
explanation:
7² + 24² = c²
49 + 576 = c²
625 = c²
c = √625
c= 25
or just know some pythagorean triples
6a. 1 - 2sin(x)² - 2cos(x)² = 1 - 2(sin(x)² +cos(x)²) = 1 - 2·1 = -1
6c. tan(x) + sin(x)/cos(x) = tan(x) + tan(x) = 2tan(x)
6e. 3sin(x) + tan(x)cos(x) = 3sin(x) + (sin(x)/cos(x))cos(x) = 3sin(x) +sin(x) = 4sin(x)
6g. 1 - cos(x)²tan(x)² = 1 - cos(x)²·(sin(x)²)/cos(x)²) = 1 -sin(x)² = cos(x)²
