Step-by-step explanation:
We have been given that for every 15 minutes of a show, there are two minutes to commercial. At this rate, Leila has seen 45 minutes of a show. We are asked to find the time for which Leila has been watching TV.
We will use proportions to solve our given problem.

Upon substituting our given values, we will get:




Therefore, Leila has been watching TV together for 51 minutes.
Answer:
86°
Step-by-step explanation:
b = 29× 2 = 58
d= [180-(86+29)]×2 = 130
a=c=x
a+b+c+d = 360
2x+188= 360
2x= 172
x= 86
a = c = 86°
4%n = 5
Simplify the equation
1/25n = 5
Multiply by 25
25 (1/25n) = (25) (5)
n = 125.
I believe its C. because you have to solve for x.
