HELP ME please⁉️⁉️⁉️⁉️⁉️⁉️MATH IS HARD

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

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p

(by the way, do you mind marking me as brainliest? i'd greatly appreciate it! mahalo! x3)

can you post the graph?
