10(0.5x + 6) = 8
5x + 60 = 8
5x = 8 - 60
5x = -52
x = -52/5
x = -10.4
Answer:
y = 1.5
Step-by-step explanation:
Given x is inversely proportional to
, then the equation relating them is
y =
← k is the constant of proportion
To find k use the condition when x = 8, y = 2
2 =
=
=
( multiply both sides by 3 )
6 = k
y =
← equation of proportion
When x = 15 , then
y =
=
=
=
= 1.5
The sum of any integer and its opposite is equal to zero

well, let's assume a year has 365 days, so 75 days is simply 75/365 of a year. We also know that your loan was $650 and you paid back $680 or namely 30 bucks extra, so the interest on those $650 is really 30 bucks.
