1. lines j and k because they have the same slope.
2.d because -1/3 is the opposite slope of 3 and it passes through that point.
6d and 3d are like terms, so you take them and add them together because they're both positive. You get 9d-e-2e. -e and -2e are also like terms so you would put these together but subtract them to get 9d-3e.

15.36x[-0.45] = 0
Reorder the terms for easier multiplication:
15.36 * -0.45x = 0
Multiply 15.36 * -0.45
-6.912x = 0
Solving
-6.912x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '-6.912'.
x = 0

The first step to solve this problem is to compute for the
total money of Veronica. You can do this by:
$35 (given to bill) / 20% (percentage of her money given to
Bill) = $175
Since you already know the total money of Veronica, you can
now compute how much she spent to buy books which are 50% of her remaining
money after giving Bill $35.
($175 - $35) x 50% = $70
Therefore, she spent $70 for her books.
$175 – $35 – $70 = $70
Therefore, she has $70 left.
