Thomas has finished 4 problems of his weekly math homework. If he needs to solve a total of 20 problems, which of the following shows the equivalent of the percentage of his math homework Thomas still needs to complete? Select all that apply.

The reason why this is the answer is because 4 out of 20 (4/20) is 0.2, so 16 out of 20 (16/20) is 0.8

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

answer: y=4000x+14000
