a right triangle has a hypotenuse of 10 feet and one leg that is 7 feet long how long is the other leg of the triangle

Solve: 3x+y=6 4x-2y=18 show all work !

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.

Calculate the missing value. round the answer to on decimal place. start with 70, increase it by 21%, and end up with
