12.)  B. 16

13.) D. 15.5

14.) A. 1 ft = 140 m

15.) C.

16.) 35

Step-by-step explanation:

12.) They are pythagorean triples (3,4,5) so if it is 12, x, 20 if you divide all of the sides by 4 you have a 3, and a 5 so that means that the last side is 4 * 4 = 16

13) Divide 186 by 12 because it is in feet and you need inches

186/12 = 15.5

14.)  Do 840/6 so that it is in meters not ft and you have like terms

840/6 = 140

15.) You have to divide the 3.6 by 2 so since C. is the only equation that will do that it is correct

16.) If you make it triangles you realize they are simmilar so the                      5 =x and 3 = 21   so it is a scale of 1 - 7 so if you multiply the 5 by 7 you have the x

5 *7=35
