Irene is making tomato soup and mac and cheese. she needs 3/4 of a cup of milk for the soup and 1 1/3 cups of mac an cheese. which equation can be used tofind how much milk she needs to make the soup and mac and cheese

Step-by-step explanation:

The amount of milk Irena required for soup= cups

The amount of milk required for mac n cheese = cups

Let x = Number of tomato soups she made.

y= Number of  mac n cheese she made.

Now , the amount of milk she needs to make the soup and mac and cheese =

( amount of milk required for soup) x  + (amount og milk required for mac n cheese) y

The amount of milk she needs to make the soup and mac and cheese (T)=  

Hence , the equation can be used tofind how much milk she needs to make the soup and mac and cheese will be :

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
