Answer:
The answer to your question is 2.6 in
Step-by-step explanation:
Data
width = ? in
width = 65 mm
Process
1.- To solve this problem, use proportions and cross multiplication
1 in ---------------------- 25.4 mm
x ---------------------- 65 mm
x = (65 x 1) / 25.4
2.- Simplification
x = 65 / 25.4
3.- Result
x = 2.6 in
Step-by-step explanation:
y=kx
say that y is the original prince and x is the sale price
15=k(10)
15/10=k
3/2=k
you can check with the next problem to check if it is the same
25=k(20)
25/20=k
5/4=k
so you take 5/4-3/2=-1/4 so the constant is -1/4
Hope that helps :)
