Erica solved the equation −5x − 25 = 78; her work is shown below. identify the error and where it was made.
−5x − 25 = 78
step 1: −5x − 25 − 25 = 78 − 25
step 2: −5x = 53
step 3: negative five times x over negative five = fifty-three over negative five
step 4: x = negative fifty-three over five

Match each equation with the operation you can use to solve for the variable. 1 subtract 10 2 divide by 10 3add 18 4add 10 5 subtact 18 6multiply by 5. 7multiply by 10. a 5 = 10p b p + 10 = 18 c p + 18 = 5 d 5p = 10

Which approach to the theory-and-research cycle does the following sequence reflect: (1) specific observations suggest generalizations, (2) generalizations produce a tentative theory, (3) the theory is tested through the formation of hypotheses, and (4) hypotheses may provide suggestions for additional observations?
