Hey there 
Answer:
- 20% of 40 is <u>8</u><u> </u><u>.</u>
Step-by-step explanation:
In this question we are given a <u>number </u><u>that </u><u>is </u><u>4</u><u>0</u><u> </u><u>.</u> And we have asked to find <u>2</u><u>0</u><u>%</u><u> </u><u>of </u><u>it </u><u>.</u>
<u>Solution</u><u> </u><u>:</u><u> </u><u>-</u>

We know that ,
- Percent ( % ) represent <u>1</u><u>/</u><u>100</u>
<u>S</u><u>o </u><u>,</u>
<u> </u>
</u>
<u>or </u><u>,</u>
<u> </u>
</u>
Now cancelling zero :

We get ,


- <u>Therefore</u><u> </u><u>,</u><u> </u><u>2</u><u>0</u><u>%</u><u> </u><u>of </u><u>4</u><u>0</u><u> </u><u>is </u><em><u>8</u></em><em><u> </u></em><em><u>.</u></em>

Answer:
Step-by-step explanation:
<u>Given</u> 
- m∠ABC = x°
- m∠BCD = 25°
- m∠CDE = 55°
- m∠DEF = 3x°
Add two more parallel lines passing through points C and D.
Consider alternate interior angles formed by the four parallel lines.
<u>The angles between the two middle lines are equal to:</u>
- m∠BCD - m∠ABC  = m∠CDE - m∠DEF
<u>Substitute values and solve for x:</u>
- 25 - x = 55 - 3x
- 3x - x = 55 - 25
- 2x = 30
- x = 15
m∠ABC = 15°
 
        
             
        
        
        
Answer:
x=2
Step-by-step explanation:
5(6x-1)-10x+5=4(x+10)-4x
simplify both sides
30x-5-10x+5=4x+40-4x
Simplify even further
20x=40
x=2
