Can somebody plz help write the equation for each question correclty thanks :D (Only if u done these before) :3

WILL MARK BRAINLIEST :DD

1. 482

2. 60

HOPE THIS HELPS YOU

Answer

20. 470 = x - 12 (Solving for X: There was 482 pages before decreasing by 12)

21. 65 = x + 5  (Solving for X: There was 60 pages read before reading 5 more)

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
