29.87127 or, if rounded, could be 29.8713, 29.871, 29.87, or 29.9
Answer:
170 people I believe
Step-by-step explanation:
93 + 47 = 140
140 + 25/2 = 140 + 13 = 170
A, C, and E. Both sides of the ratio has to change at the same time. If you multiply both sides by 2 you get 8:10. If you divide both sides by 2 you get 2:2.5. and if you divide by 1.5 you get 3:3.75.
Sorry if my explanation doesn't make sense
