Answer:
x=7
Step-by-step explanation:
this is a ratio problem which the ratios could be seen as fractions
x/14 = 10/20
then you and use the cross multiply method to solve this equation
20x = 140
x = 7
also another way is to find the previous 10/20 which gives you 1/2 and 1/2 of 14 is 7
7:14 = 10:20
The answer is x+8.
Because you gotta factor out first and then cancel.
It could be any number, is there choices?
6) x = 40.5
8) x = 16.5
6) 45/x = 20/18
simplify and cross-multiply to get:
45/x = 10/9
10x = 405
x = 40.5
8) 22/8 = x/6
11/4 = x/6
4x = 66
x = 33/2
x = 16.5
3/10
7+3= 10 so 7+3=10/10 which is one mile
