<span>Let x = represent the number of weeks of deposits
A = 120 + 5x the account balance after x weeks
The account balance is directly proportional to the number of weeks of deposits if:
A/x = constant
(120 + 5x)/x = 120/x + 5 is not a constant
For example:
After 1 week there will be: 120 + 1*5 = $125 on the account
After 2 week there will be: 120 + 2*5 = $130 on the account
After 3 week there will be: 120 + 3*5 = $135 on the account
But 125/1 <> 130/2 <> 135/3
The account balance is not proportional to the number of weeks of deposits.</span>
The answer i got was
n=-3/4,n=-1
The Corrected Problem is :
2:x and 12:18 identify the value of x that makes each pair of ratios equivalent .
Solution:
If a pair of Ratios are equivalent then we can write
263.25 is the volume of the box in inches cubes you have to multiply 4.5 by 9 by 6.5
