John bought 3 cakes and 24 brownies for a total of $81. The next month in February, he bought 2 cakes and 32 brownies for $86. (Let c=price of a cake and b=price of a brownie)

One of the same side angles of two parallel lines is 20° smaller than the other one. find the measures of these two angles.

Me with this one question, and i'll upvote the brainliest answer

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.
