What is (1.6x + 7.3) + (–0.6x + 2) – (7.8 – 3.4x), simplified?

(1.6x + 7.3) + (–0.6x + 2) – (7.8 – 3.4x)

1.6x + 7.3 – 0.6x + 2 – 7.8 + 3.4x

1.6x – 0.6x + 3.4x + 7.3 + 2 – 7.8

x + 1.5

If a • b*2 = 1.8 x 10*-7, and c•b/d = 7.2 x 10*-4, find the value of a•d*2/c*2

Determine the number of outcomes in the event. decide whether the event is a simple event or not. upper a computer is used to select randomly a number between 1 and 9 comma inclusive. event upper b is selecting a number greater than 4. event upper b has nothing outcome(s). is the event a simple event? (yes or no) because event upper b has (fewer than, exactly, more than) one outcome.

Solve the problem. a student earned grades of c, a, b, and a in four different courses. those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. the grading system assigns quality points to letter grades as follows: a = 4, b = 3, c = 2, d = 1, and f = 0. compute the grade point average (gpa) and round the result to two decimal places. 3.40 3.50 8.75 2.18
