Luna mixes 3/4 cup of orange juice with 3/8 cup of cranberry juice. She gives 5/8 cup of juice to mags. How much is left in luna
Debora [2.8K]

Answer:

The answer is 1/2

Step-by-step explanation:

First you must the least common denominator so that you can add the two fractions. The least common denominator between 3/4 and 3/8, would be 8.

To get 3/4 to the least common denominator, you have to multiply top and bottom by 2. The product of this will be 6/8.

Next you add the two fractions: 6/8 + 3/8 = 9/8

Simplify your improper fraction to get on and 1 eighths or in number form 1 1/8

After this you must subtract how much she gave away so you can use your improper fraction to make it easier and subtract five eighths from nine eighths: 9/8 - 5/8 = 4/8

So, Luna has four eighths of a glass left but first you must simplify your answer. both 4 and 8 divide by 4 to get 1/2.

So Luna's glass only has 1/2 in the cup.

Make sure you be optimistic and see it as half full, instead of the pessimistic view of half empty. Remember to stay positive and share good vibes. Hope this answer helps you.

Caleb and Mike both score the same amount of points in a game. Caleb has fifteen less than the total number of points. Mike has
elena-s [515]
Answer:
129 points
Step-by-step explanation:
Let L and C represent the scores of Luke and Caleb, respectively.
L = 2C -15 . . . . . Luke scored 15 less than twice the number Caleb did
L +C = 201 . . . . . they scored 201 points altogether
Add twice the second equation to the first:
2(L +C) + (L) = 2(201) + (2C -15)
3L +2C = 387 +2C . . . . simplify
3L = 387 . . . . . . . . . . . . .subtract 2C
L = 387/3 = 129 . . . . . . .divide by 3
Luke scored 129 points.

Ksivusya [100]

Answer:

Buffalo mild wings offers the lowest price per wing ($0.83).

Step-by-step explanation:  

Let us find unit price per buffalo wing of each restaurant.

\text{Unit rate for buffalo bills}=\frac{\$7}{8\text{ wings}}

\text{Unit rate for buffalo bills}=\frac{\$0.875}{\text{ wing}}

Upon rounding our answer to nearest cent we will get,

\text{Unit rate for buffalo bills}=\frac{\$0.88}{\text{ wing}}

Therefore, buffalo bills offers each wing for $0.88.

\text{Unit rate for buffalo mild wings}=\frac{\$10}{12\text{ wings}}

\text{Unit rate for buffalo mild wings}=\frac{\$0.83333}{\text{ wing}}

Upon rounding our answer to nearest cent we will get,  

\text{Unit rate for buffalo mild wings}=\frac{\$0.83}{\text{ wing}}

Therefore, buffalo mild wings offers each wing for $0.83.

\text{Unit rate for wingers}=\frac{\$17}{20\text{ wings}}

\text{Unit rate for wingers}=\frac{\$0.85}{\text{ wing}}

Therefore, wingers offers each wing for $0.85.

We can see that buffalo mild wings offers the lowest price per wing that is $0.83 per wing.
