Answer:

8.333333

Step-by-step explanation:

3x+2(4+6x)=133

3x+8+12x=133 First I distibuted the 2 too the 4 and 6x

15x+8=133 Then I added the x es 3x and 12x

15x+8-8=133-8 Then I subracted 8 from both sides

15x=125 That leaves with this

15x/15=125/15 Now I divide 15 from both sides to isolate x

x= 8.33333 that is the answer

check

3x+2(4+6x)=133

3*8.333333+2(4+6*8.333333)=133

24.999999 +2(4+ 49.999998)=133

24.999999+2( 53.999998)=133

24.999999+107.999996=133

132.999995=133

Answer:

51 minutes.

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.

$\frac{\text{Minutes of TV show + Advertisement}}{\text{Minutes of TV show}}=\frac{15+2}{15}$

$\frac{\text{Minutes of TV show + Advertisement}}{\text{Minutes of TV show}}=\frac{17}{15}$

Upon substituting our given values, we will get:

$\frac{\text{Minutes of TV show + Advertisement}}{45}=\frac{17}{15}$

$\frac{\text{Minutes of TV show + Advertisement}}{45}\times 45=\frac{17}{15}\times 45$

$\text{Minutes of TV show + Advertisement}=\frac{17}{1}\times 3$

$\text{Minutes of TV show + Advertisement}=51$

Therefore, Leila has been watching TV together for 51 minutes.
