Answer:
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
2x = 5 * 3.58
divide both sides by 2
x = (5 * 3.58)/2
x = $8.95
22.) 2 tires = $240
x tires = $ 1080
240 x = 2 * 1080
divide by 240
x = (2* 1080)/240
x = 9
29.) 2 in = 2.5 hrs
3.6 in = x
2x = 3.6 * 2.5
divinde both sides by 2
x = (3.6 * 2.5)/2
x = 4.5 hrs
