20.) x = 20

21.) x = 8.95

22.) x=  9

29.) x = 4.5 hrs

only did a couple as an example

Step-by-step explanation

20.) 1/4 in = 1 m

      5 in = x m

cross multiply

x/4 = 5

multiply both sides by 4

x = 20

21.) 2L  = 3.58

      5L = x

cross multiply

2x = 5 * 3.58

divide both sides  by 2

x =  (5 * 3.58)/2

x = $8.95

22.) 2 tires = $240

     x tires = $ 1080

cross multiply

240 x = 2 * 1080

divide by 240

x = (2* 1080)/240

x = 9

29.) 2  in = 2.5 hrs  

      3.6 in  = x

cross multiply

2x = 3.6 * 2.5

divinde both sides by 2

x = (3.6 * 2.5)/2

x = 4.5 hrs
