Answer:
16
Step-by-step explanation:
30-10=20
20 divided by 1.25 = 16
Answer:
You could just replace all the given possible values of k in the inequality and see which ones are solutions, but let's solve this in a more interesting way:
First, remember how the absolute value works:
IxI = x if x ≥ 0
IxI = -x if x ≤ 0
Then if we have something like:
IxI < B
We can rewrite this as
-B < x < B
Now let's answer the question, here we have the inequality:
I-k -2I < 18
Then we can rewrite this as:
-18 < (-k - 2) < 18
Now let's isolate k:
first, we can add 2 in the 3 parts of the inequality:
-18 + 2 < -k - 2 + 2 < 18 + 2
-16 < -k < 20
Now we can multiply all sides by -1, remember that this also changes the direction of the signs, then:
-1*-16 > -1*-k > -1*20
16 > k > -20
Then k can be any value between these two limits.
So the correct options (from the given ones) are:
k = -16
k = -8
k = 0
Based on the data given, the length of line segment AC is 2.29
<h3>What is the length of side AC?</h3>
Based on the given data:
- AC=BC
- AB=3
- line segment CD is perpendicular to line segment AB
- CD= sqrt 3
The triangle ABC is an isosceles triangle.
The line segment AC is the hypotenuse of the the triangle ACD.
The length of AD = 3/2
In conclusion, the length of AC is 2.29
