Answer:
B)5/3
Step-by-step explanation:
"3x + 5y = 15."
Rewrite in slope-intercept form.
The slope-intercept form is  
y=mx+b
where  m is the slope and  b  is the y-intercept.
y=mx+b
Subtract  3x  from both sides of the equation.
5y=15−3x
Divide each term by  "5"  and simplify.
5y/5=15/5−3x/5
"5" and "5" cancel each other out
Divide  15  by  5
y=3-3x/5
Reorder  3  and  −3x/5
y=-3x/5+3
Rewrite in slope-intercept form.
y=−3/5x+3
Slope:-3/5
The equation of a perpendicular line to  y=−3x/5+3  must have a slope that is the negative reciprocal of the original slope.
<em>m</em>perpendicular=−1/(−3/5)
Simplify the result.
mperpendicular=5/3
hope this helps!

If the probability of spinning an A once is 1/12, then the probability of spinning an A 3 times is 3 × 1/12. 
3 × 1/12 = 3/36 
Simplify 
3/36 = 1/12
        
             
        
        
        
Answer:
- 30 adult tickets,
- 50 kids tickets
Step-by-step explanation:
<u>Given</u>
- Cost of adult ticket = $8.50
- Cost of kids ticket = $7.00
- Number of tickets = 80
- Total cost = $605
Let the adult ticket be a and kids be k
<u>We got equations</u>
- a + k = 80
- 8.5a + 7k = 605
<u>From the first equation we get</u>
<u>Substituting k in the second equation</u>
- 8.5a + 7(80 - a) = 605
- 8.5a - 7a + 560= 605
- 1.5a = 45
- a = 45/1.5
- a = 30
<u>Then finding k</u>
