In this unit, you solved two-step equations. a two-step equation is an equation of the form px + q= r. it takes two steps to solve for the variable x. for example, 3× +(-5)= 19 is a two-step equation. how could you transform this particular equation to create a three step equation? list several ways you could transform it using common math operations. next, try solving one of the three step equations you created for x. (use a guess and check strategy, if necessary.) what additional step is required to find the solution? in your opinion, is solving the three step equation more difficult than solving a two step equation? why are why not? do you think there is limit to the number of steps it takes to solve an equation? explain ( i need the work to be shown for this )

Atest of sobriety involves measuring the subject's motor skills. a sample of 31 randomly selected sober subjects take the test and produce a mean score of 64.4 with a standard deviation of 2. a claim is made that the true mean score for all sober subjects is equal to 65. for each part below, enter only a numeric value in the answer box. for example, do not type "z =" or "t =" before your answers. round each of your answers to 3 places after the decimal point. (a) calculate the value of the test statistic used in this test. test statistic's value = (b) use your calculator to find the p-value of this test. p-value = (c) use your calculator to find the critical value(s) used to test this claim at the 0.2 significance level. if there are two critical values, then list them both with a comma between them. critical value(s) =
