The solution is step 3. In step three they gave themselves two answers which is wrong. The lines mean absolute value, which means that it should be +3 not -3.

I need help answering this question.
Darina [25.2K]
Her credits need to be AT LEAST EQUAL TO OR GREATER THAN 144 (credit hours) so we can eliminate choices B and D.

She already completed 4 semesters in which she receives 15 credit per semester.

This expression can be written as 4(15).

She needs to do a certain remaining hours of credit which can be represented by c and only c without any other coefficient.

So, the most reasonable choice here is A.

<h3>Exact Answer: (160/3)pi</h3><h3>Approximate Answer: 167.47</h3>

The approximate answer results when you use pi = 3.14, and this approximate answer is rounded to two decimal places

note that (160/3)pi is the same as 160pi/3

========================================================

Work Shown:

r = radius = 4

h = height = 10

V = volume of cone

V = (1/3)pi*r^2*h

V = (1/3)pi*4^2*10

V = (160/3)pi exact answer

V = (160/3)*3.14

V = 167.46666....

V = 167.47 approximate answer rounded to two decimal places

x = -64

Step-by-step explanation:

Step 1: Write out equation

9 - 3/4x = 57

Step 2: Subtract 9 on both sides

-3/4x = 48

Step 3: Multiply both sides by -4/3

x = -64
