What is the value of x in the equation 2(x-4) = 4(2x + 1)?

Marking brainliest rewrite the equation x = 65 - 60p by factoring the side that contains the variable p.

Aprobability experiment is conducted in which the sample space of the experiment is s={7,8,9,10,11,12,13,14,15,16,17,18 }, event f={7,8,9,10,11,12}, and event g={11,12,13,14}. assume that each outcome is equally likely. list the outcomes in f or g. find p(f or g) by counting the number of outcomes in f or g. determine p(f or g) using the general addition rule.
