Jenna won 77 toys playing basketball at her school's game night. Later, she gave four to each of her friends. She only has 9 remaining. How many friends does she have?

Jenna has 17 friends.

The equation can be written as:
77 - 4x = 9 where 77 is the total number of toys, 4 is how many toys she gave to each friend, x is the number of friends, and 9 is the toys remaining.

To solve for x, the number of friends:
77 -4x=9

Subtract 77 from both sides
77-77 -4x= 9-77
-4x= -68

Then divide both sides by -4 to isolate x.
-4x/-4 = 1x and -68/-4 = 17.
1x= 17, so the number of friends is 17.

You need to include the original coordinates of the triangle to answer this. and how much does it translate (move left right up down)
