Answer:
(5, 1)
Step-by-step explanation:
-4+6-1=1.
2l+2w=24
l=3+w
The first equation comes from the perimeter formula. Since it is a rectangle, there are two lengths and two widths, which must all be added to get the perimeter. The second equation shows that the length is equal to the width plus three. In order to solve this equation, the substitution method should be used, since the one equation is already set equal to one of the variables (L)
2l+2w=24
l=3+w
2(3+w)+2w=24
Use distributive property to get rid of the parentheses
2(3+w)+2w=24
2(3)+2(w)+2w=24
6+2w+2w=24
Simplify like terms on the left side of the equation
6+2w+2w=24
6+4w=24
Subtract six from each side so that all of the w's are on one side
6+4w-6=24-6
4w=18
Divide each side by four to find the value of one w
4w/4=18/4
w=4.5
Plug 4.5 into the one equation to find the value of l
l=3+4.5
l=7.5
Put the numbers into the first equation and simplify:
2(7.5)+2(4.5)=24
15+9=24
24=24
So the length would be 7.5 inches, and the width would be 4.5 inches
Answer:
$151.78
Step-by-step explanation:
The sum of the amounts in the "Principal Paid" column is ...
$25.67 +25.52 +25.37 +25.22 +25.07 +24.93 = $151.78
The amount Patrick has paid against his original charge is $151.78.
_____
<em>Comment on minimum payment</em>
If Patrick continues to make the minimum payment, it will take more than 70 years for the balance remaining to drop below $25. In that time, Patrick will have paid about $15,000 to the credit card company.
5y<7 <------- That is the answer. BTW (by the way) the variable needs to always be on the rights side.
Hope this helps!!!!!!!!!
