Final answer:
To simplify the expression negative one-fifth (5 x 20) minus one-fourth (4 x minus 28), multiply each part separately and subtract the results. The simplified expression is -8.
Step-by-step explanation:
To simplify the expression negative one-fifth (5 x 20) minus one-fourth (4 x minus 28), we need to evaluate each part separately and then subtract the two results. Let's start with the first part: negative one-fifth (5 x 20). This means we need to multiply 5 and 20, and then multiply the result by negative one-fifth. So, 5 x 20 equals 100, and then negative one-fifth of 100 is -20.
Next, let's simplify the second part: one-fourth (4 x minus 28). This means we need to multiply 4 and -28, and then multiply the result by one-fourth. So, 4 x -28 equals -112, and then one-fourth of -112 is -28.
Finally, we subtract -20 from -28 to get -8. Therefore, the simplified expression is -8.
