Step-by-step explanation:
The last one is correct
Hello there! The value of y is -5/4.
So, basically look at it like an ordered pair, (x, y). When we have (5, y), we have a value of x and are looking for a value of y. To do this, plug the value for x (5) into the equation and solve for y.
5x+4y-20=0
5(5)+4y-20=0
Now that you have the value for x, solve for y.
5(5)+4y-20=0 - Start by multiplying out the parenthesis.
25 + 4y - 20 = 0 - Next, combine like terms.
25 - 20 + 4y = 0
5 + 4y = 0 - Now, subtract 5 from both sides.
4y = -5 - Lastly, divide both sides by 4.
y = -5/4.
This is your final answer. I hope this helps and have a great day! :)
Answer:
Total volume of all the bins = xS + yL
Step-by-step explanation:
Given: x cubic inches represent the volume of the smaller bin and y cubic inches represents the volume of the larger bin. The store has S smaller bins and L larger bins.
To find: an expression that represents the total volume of all the bins
Solution:
The volume of the smaller bin = x cubic inches
The volume of the larger bin = y cubic inches
Also, the store has S smaller bins and L larger bins
So,
Total volume of all the bins = xS + yL
