Answer:
Let x = # of commercials
y = # of movies
<u>System of Equations:</u>
x + y = 90
40x + 110y = 500
Step-by-step explanation:
We have to set our variables before we start solving. After setting the variables, we can set up the equations. If x = # of commercials and y = # of movies, then we can assume x + y = 90, as there have been a total of 90 commercials and movies played altogether. Then, we know that their worth is $500, so the price of all the commercials played and the price of all the movies played (which is 40x + 110y) sum to $500.

Let x represent the time spent for valleyball
Then swimming will be 2x
x + 2x = 4.5
3x = 4.5
x = 4.5/3
x = 1.5
Time spent on valleyball: 1 1/2 hours
Time spent on swimming: 3 hours
The answer is D, good night
Glass bottles =total number of bottles - numeber of bottle of plastic
gass bottles=50-19=31 bottles of glass.
percent of the bottles are glass=(number of bottles of glass*100%) / total number of bottles.
percent of the glass bottles=(31 bottles * 100%) / 50 bottles=62%
Answer: the percent of the bottles of glas is 62%
Answer: The GREATEST number of bookmarks that Logan can make = 31.
Step-by-step explanation:
GIven: Total petals = 95
Number of petals required for each bookmark = 3
Number the number of bookmarks can be prepared from 95 petals = 95 ÷ (Petals required of each bookmark)
= 95÷3
![=31\dfrac{2}{3}\ \ \ \approx31\text{ [Round to the nearest whole number.]}](https://tex.z-dn.net/?f=%3D31%5Cdfrac%7B2%7D%7B3%7D%5C%20%5C%20%5C%20%5Capprox31%5Ctext%7B%20%20%20%20%5BRound%20to%20the%20nearest%20whole%20number.%5D%7D)
i.e. The GREATEST number of bookmarks that Logan can make = 31.
