Does anyone know how to do this, I need this answer for my final exam PLEASE In the figure below, line m is parallel to line n. If m∠3 = (12x + 5) degrees and m∠5 = (30x - 35) degrees:

Solve for x. (2 point)

Find the angle measure of all eight angles below. (4 point)

At his new job, jeremiah can choose an hourly rate of $9 plus a $50 weekly bonus for opening the store, or an hourly rate of $10 per hour with no opening bonus. the equations model his salary options. y = 9x + 50 y = 10x

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.

I’m still confused on how to work the percentages
