Set up a system of equations:
You can apply the Substittution Method to solve the system of equations:
1. Solve for "o" from the second equation:
2. Substitute it into the first equation and solve for "m":
3. Substitute the value of "m" into and evaluate, in order to find the value of "o". This is:
Answer:
cup of pineapple juice.
Step-by-step explanation:
We are told that Francine uses 2/3 cup of pineapple juice for every 1/3 cup of orange juice to make a smoothie. In order to get the number of cups of pineapple juice Francine will use for 1 cup of orange juice, we will apply the following expression;
2/3 cup of pineapple juice = 1/3 cups of orange juice
1 cup of pineapple juice = x cups of orange juice
Cross multiply
divide both sides of the equation by 3
divide both sides by 2
Hence Francine uses number of cups of pineapple juice for 1 cup of orange juice.
