M < PQS + m < RQS = 180° because they are supplementary angles.

Therefore:
(3x + 3) + (x + 19) = 180

3x — 3 + x + 19 = 180

4x + 16 = 180

Subtract 16 from both sides

4x — 16 = 180 — 16

4x = 164

Divide both sides by 4:

4x/4 = 164/4

x = 41

Therefore, the correct answer is x = 41

ankoles [38]
Answer:

24 video games

Step-by-step explanation:

Let x represent number of video games.
We have been given that a video game store allows customers to rent games for $4.75 each. So the cost of renting x video games would be 4.75x.

We are also told that customers can also buys a membership for $54 annually, and video games would only cost $2.50 each. The cost of renting x video games after membership would be 2.50x + 54

To find the number of video-games that will cost same for both options, we will equate both expressions as:

4.75x = 2.50x + 54
4.75x - 2.50x = 2.50x - 2.50x + 54


Therefore, a customer would have rent 24 video games in a year in order for the two options to be equal.

LekaFEV [45]

Answer:

D. 116

Step-by-step explanation:

Let the grasshoppers with a white marking be 2x.

Let the grasshoppers without a white marking be 3x.

2x + 3x = 290

5x = 290

x = 290 / 5

x = 58

The grasshoppers with a white marking

= 2x

= 2 ( 58 )

= 116
