Answer:

All real numbers are solution for the inequality.

Step-by-step explanation:

Given expression:

2(-6n-5)

Solving the inequality.

Using the distribution.

(2(-6n))+(-2(-5)

-12n-10

Adding 12n to both sides.

-12n+12n-10

We have,

-10

The above statement is always true and thus the inequality has all real number solutions.

The number line graph for the inequality can be shown.

Craig went to see a play at a theater downtown. The first act was 45 minutes long. Intermission lasted for 55 minutes and the se
Digiron [165]

Answer:

The play started at 5:10 PM.        

Step-by-step explanation:

We are given the following in the question:

Length of first act = 45 minutes

Length of intermission = 55 minutes

Length of second act = 1 hour and 10 minutes

1 hour = 60 minutes

Thus, length of second act =

=60+10\\=70\text{ minutes}

The second part ended at 8:00 PM. We have to find the starting time of play.

Starting time of play =

= 8-\dfrac{45+55+70}{60}\\=8 - 3\text{ hours} + 10\text{ minute}\\=5:10\text{ PM}

Thus, the play started at 5:10 PM.

Solve the following system of equations: x - 2y = 14 x + 3y = 9
Margarita [4]
Solve your system of equations step by step.

x−2y=14;x+3y=9

Solve x−2y=14 for x:

x−2y+2y=14+2y (Add 2y to both sides)

x=2y+14

Substitute (2y+14) for x in x+3y=9:

x+3y=9

2y+14+3y=9

5y+14=9(Simplify both sides of the equation)

5y+14+−14=9+−14 (Add -14 to both sides)

5y=−5

5y5=−55 (Divide both sides by 5)

y=−1

Substitute (−1) for y in x=2y+14:

x=2y+14

x=(2)(−1)+14

x=12(Simplify both sides of the equation)



So,

y=-1
x=12

Answer is C)
