Three sisters want to. Buy a pda for their fauther for fauthers day. The least expensive pda in the sorr isn$360. Writenand slove an inequality to fund the least anout of koney each girl would have ti contrubute if each contributenand equal amount

$120

Step-by-step explanation:

I would like to rewrite your question for others easy to understand:

"Three sisters want to Buy a pda for their father for fathers' day. The least expensive pda in the store  is $360. Writen and slove an inequality to fund the least amout of money each girl would have ti contrubute if each contribute an equal amount"

Let X is the the amount one girl contribute, we have 3 girls => 3X

The least expensive pda in the store  is $360, so the total contributed amount must be equal or smaller than the pda cost

<=> 3X  

<=> X

So the least amout of money each girl would have to contrubute is $120

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
