y = number of days
35.50 + 18.25 y = 163.25
18.25 y = 163.25 - 35.50
18.25y = 127.75
y = 127.75 / 18.25
y = 7
so Martin has hired the machine for 8 days
( first day paid 35.50), then 7 days for 18.25
The number beside the letter . for example 6x, 6 would be the variable

oh! thanks for points
but this is yr question or what????
Answer:
-0.25 ; 120 seconds 72 seconds
Step-by-step explanation:
Dive rate is constant :
Change in elevation after 8 seconds :
18 feets to 20 feets below
Rate of change = distance / time
(18 - 20) feets / 8 seconds
(-2 / 8) = - 0.25 feets per second
To reach 50.feets :
She needs to cover (50 - 20) = 30 feets
Time = distance / speed ; 30 feets / 0.25 = 120 seconds
The answer is 11367736100!
