Spike and Tyke need new bones and treats. Their owner bought a combination of 11 bones and treats and spent a total of
$95 on bones that cost $7 each and treats that cost $13 each.

Create and solve a set of equations to model this situation

Can (3,5 and square root 34) be sides on a right triangle?

X+ y = 5 ; x - y =3 solve using linear combination

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
