Write an absolute value inequality to represent each situation.

Mathematics
1 answer:
Minchanka [31]3 years ago

Answer:

║ x - 231 ║ ≤ 459

Step-by-step explanation:

Since we have 228 ft below sea level, this is x' = -228 ft. Also,  we have 690 ft above sea level, this is x" = 690 ft.

Since x is our elevation in feet, x ranges from -228 ≤ x ≤ 690.

To write an absolute value equation for x, we first take the average of the two values for the ranges to obtain the ideal value of x.

So, ideal value = [690 + (-228)]/2 = 462/2 = 231.

We also find the tolerance by taking the difference of both values and dividing by 2. So tolerance = [690 - (-228)]/2 =  [690 + 228)]/2 = 918/2 = 459.

Subtracting 231 from each value of the inequality we have

-228 - 231 ≤ x - 231 ≤ 690 - 231

-459 ≤ x - 231 ≤ 459

Since we have in magnitude the values on the left and right side of the inequality,

So ║ x - 231 ║ ≤ 459

I need help with this question please !!
RSB [31]

Answer:

100, because 180 - 50 - 90 = 40

The vertical angles theorem is applied, so now angle DCE is 40

And since CE = ED, its isosceles triangle, so base angles are equal, so 40 and 40.

180 - 80 = 100 = Angle E.

What is negative 1 equals 5+x/6?
Annette [7]

Hello there,

The equation that is give to us is as follows:

  • -1 = 5 + \frac{x}{6}

In order to solve for x we would first subtract 5 from both sides and then multiply by 6:

  • -1 -5 = -6 ÷ 6 = -1

This means that x would equal to -1 given the equation above.

Hope I helped,

Amna

How can i solve 16x+16= 20x +5
miss Akunina [59]

Answer:

x=11/4

Step-by-step explanation:

You want all of the x's on one side, so you can subtract 16x from both sides, so you get 16 = 4x+5. Then, you subtract 5 from both sides to get 4x = 11. Finally, you divide by 4 so you get x=11/4.

A 18 -person road crew is scheduled to finish repairing a highway in 10 days. On the morning of the fifth day, several workers o
Pavlova-9 [17]

Answer:

<u>9 workers finished the repairs, therefore 9 members of the original crew were removed. </u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Original crew scheduled to finish repairing a highway = 18 person

Number of days remaining to finish the work = 10 - 4 = 6 days

Number of days that the rest of the crew finished the repairs = 12 days

2. How many workers were removed from the crew?

We will use Inverse Rule of Three to answer this question because the less workers the crew has the more time it will take them to finish the repairs, as follows:

Workers                Days

     18                        6

      x                        12

12x = 18 * 6 (Inverse Rule)

12x = 108

x = 108/12

x = 9

<u>9 workers finished the repairs, therefore 9 members of the original crew were removed. </u>
