Answer:
No solution.
Step-by-step explanation:
The range of the abs. val. function is [0, infinity). In other words, the output of this function is never negative. Thus, the equation you have posted has no solution.
Answer:
Angle LJK = 75 degrees
Step-by-step explanation:
Here, we want to fill the boxes
From the diagram;
angle HJL and LJK are supplementary (they add up to 180 degrees)
Angle HJL + Angle LJK = 180
angle LJK = 180-105
Angle LJK = 75 degrees
Answer:
<h2>11</h2><h2 />
Step-by-step explanation:
<h3>let w= 5</h3><h3 /><h3>4w - 9</h3><h3>= 4 × (5) - 9</h3><h3>= 20 - 9</h3><h3>= 11</h3>

Answer:
x= 14
Step-by-step explanation:
When the triangles are similar, they should have a similar ratio that makes one side equal to another. In this case, the ratio is 1.5 as 24 divided by 16 is 1.5. Now, taking the side that is "similar" to the x-value which is 21, we divided 21 by 1.5 resulting in x= 14.
Jamal's score is 80
<u>Explanation:</u>
Given:
Number of questions = 100
Let w be the number of wrong answers
Let r be the number of right answers
According to question,
r = 4w
r + w = 100
Solving both the equations we get:
4w + w = 100
5w = 100
w = 20
If w = 20 then r = 4 X 20 = 80
Therefore, Jamal's score is 80
