Hello,
if the solution is infinite : the line x-3y=4 ,
so there is one line and not 2
==>x-3y=4 multiplied by 2
2x-6y=8=Q
Q=8
S = (n-2) * 180
s = (14-2) * 180
s = 2160
2160/ 14 = 154.3
The answer is A
The answer for this question is "y = -5/3 and x = 8/3"
We have
-9 + 7 = -2
You can also rewrite this as
7 - 9 = -2
If it makes you more comfortable.
Hope this helps.
First you have to know the price of item.
EX: Say a candy car costs $1.50.
The candy bar was marked down 30%.
$1.50 x 30/100 = $.45
The item will decrease $.45.
$1.50 - $.45 = $1.05
