Answer:
81
Step-by-step explanation:
i added it all
I’m pretty sure it would be a and b
I would write the missing variable as x. It's what everyone uses.
Anyway, 91 divided by x is 65.
The way we can do this is reverse 65 and x.
91 divided by 65 = x.
91 divided by 1.4 = 65
65 x 1.4 = 91
x (or ?) = 1.4
60:1
I think anyway, I just know that there are 60 seconds in one minute so sixty to one, not completely sure tho
