Madison and Ella are painting their bedroom walls pink. The clerk at the home store calculated that they would need two gallons
Elza [17]

Answer:

Madison and Ella do not have enough paint to cover the walls after they mix the red and white paint together.

Step-by-step explanation:

Volume of red paint = \frac{3}{8} gallon

Volume of white paint = 1\frac{5}{12} gallon=\frac{17}{12} gallon

Total volume of pink paint by mixing red and white :

\frac{3}{8} gallon+\frac{17}{12} gallon

=\frac{3\times 12+17\times 8}{8\times 12}=\frac{172}{96}=\frac{43}{24} gal

\frac{43}{24} gallon\approx 1.79 gallon

Volume of total paint required by them as calculated by clerk = 2 gallons

2 gallons>\frac{43}{24}

So, this means that Madison and Ella do not have enough paint to cover the walls after they mix the red and white paint together.

Yanka [14]
I am so so sorry, i know what it feels like to lose a friend. the advice i was given was to be nice to them even if they are mean to you and try to get your mind off it. i can suggest listening to music and watching minecraft twitch streamers like tommyinnit dreamwastaken and georgenotfound seriously, they help anxiety and boredom. try to stay calm when in court and if you look it up on the internet, there is a military method to sleep that makes me settle down to sleep. then you can take deep breaths and maybe listen to white noise or music. so so sorry this is happening to you :((

Hatshy [7]

Answer:

5 months

Step-by-step explanation:

Make the question into an equation where the cost of one gym equal to the cost for the other.

60x = 100 + 40x

x represents how many months

20x = 100

x = 5

It would take 5 months of membership for the costs to be the same.
