Answer:
x = -5
Step-by-step explanation:
1/2(x-5)=2x+5
Multiply each side by 2
2(1/2(x-5))=2(2x+5)
x-5 = 4x+10
Subtract x from each side
x-5-x = 4x+10-x
-5 = 3x+10
Subtract 10 from each side
-5-10 = 3x+10-10
-15 =3x
Divide by 3
-15/3 = 3x/3
-5 =x

Answer:
The answer is the option B, which is: 46 degrees.
The explanation for this problem is shown below:
1. According to the Law of reflection, the angle of incidence is equal to the angle of reflection.
2. Therefore, if Ф1 is the angle of incidence and Ф2 is the angle of reflection, you have:
Ф1 = 46 degrees
Ф1 = Ф2
Ф2 = 46 degrees
So, the answer is the option mentioned before.
<span>5(x+1)= 4(x-1)+x
5x + 5 = 4x - 4 + x
5x +5 = 5x -4
5 </span>≠<span> -4

Answer:
0.125 and 1/8
Step-by-step explanation:
To convert a percentage to a decimal, divide by 100 to move 2 decimal places to the left.
12.50% / 100 = 0.125
To convert a percentage into a fraction, rewrite the decimal number you got and put it over 1. Multiply the numerator and denominator by 1000 to move 3 decimal places to the right and get your fraction.
· 
= 125/1000
Divide the numerator and denominator by the GCF, 125, to get your simplified fraction.
125/125 = 1
1000/125 = 8
125/1000 = 1/8
