Sofia is buying new skis. She finds that the average price of skis is $500 but the actual price could differ from the average as
prisoha [69]
The equation that best represent the actual prices of the skis is,
                    I x - 500 I ≥ 250
Solving the absolute value equation,
                       x ≤ 750 and x ≥ 250 
Thus, the prices of the skis ranges from 250 to 750.

Solve for x. Round to the nearest tenth, if necessary.
natka813 [3]

Answer:

25.5

Step-by-step explanation:

first find angle E.

remember, all angles in a triangle always add up to 180 degrees.

E = 180 - 90 - 20 = 70 degrees

now we use the law of sines.

ED/sin(20) = DC/sin(70) = EC/sin(D)

EC = x

sin(D) = sin(90) = 1

24/sin(70) = x/1 = x

x = 25.5

Solve |2x - 5| = 4. {x | x = -4.5 or x = 4.5} {x | x = 0.5 or x = 4.5} {x | 0.5 < x < 4.5}
kotykmax [81]

<u><em>Answer:</em></u>

{x | x = 0.5 or x = 4.5}

<u><em>Explanation:</em></u>

<u>Before we begin, remember that:</u>

The modulus gives the positive value of what's inside it.

<u>This means that:</u>

|a| = |-a| = a

<u>Now, for the given, we have:</u>

|2x-5| = 4

<u>From the above rule, we can deduce that:</u>

<u>either:</u>

2x - 5 = 4

2x = 4 + 5 = 9

x = 4.5 ............> first solution

<u>Or:</u>

2x - 5 = -4

2x = 5-4 = 1

x = 0.5 ..........> second solution

<u>Now, we check:</u>

<u>at x = 4.5</u>: |2(4.5)-5| = |9-5| = |4| = 4 ..........> first solution verified

<u>at x = 0.5</u>: |2(0.5)-5| = |1-5| = |-4| = 4 .........> second solution verified

Hope this helps :)
