Answer:
Step-by-step explanation:
Parallel lines. A & B are corresponding angles and corresponding angles are equal.
∠A = ∠B
8x - 8 = 5x + 25
Add 8 to both sides
8x - 8 + 8 = 5x + 25 + 8
8x = 5x + 33
Subtract 5x from both sides
8x - 5x = 5x +33 - 5x
3x = 33
Divide both sides by 3
3x/3 = 33/3
x = 11
∠B = 5x + 25 = 5*11 + 25 = 55 +25 = 80
∠B = 80°
Step by step explanation
<u>let x be the number of minutes and y be the total charges per month</u>
<em>A. Melissa's cell phone plan charges two cents a minute plus a $10 monthly fee. </em>
<em>y=0.02x+10</em>
<em> </em>
<em>B. Sandra's cell phone plan charges seven cents a minute. </em>
<em>y=0.07x</em>
<em />
<em>C. Holly's cell phone plan charges five cents per minute. She also receives a $5 discount each month.</em>
<em>y=0.05x-5</em>
<em />
<em> D. Alicia's cell phone plan charges six cents per minute plus a $5 monthly fee.</em>
<em>y=0.06x+5</em>
