Sam had the better score
To compare their scores we require to convert them into percentages
Express as a fraction and multiply by 100%
× 100% = 86.7% ( to 1 dec. place )
× 100% = 83.3% ( to 1 dec. place )
Answer:
Total pints of cream will they need for the pasta = 7 pints
Step-by-step explanation:
Given - Pasta Place needs to make pasta with garlic cream sauce for 80 guests at a party. One batch of pasta calls for 3 cups of cream and feeds 10 people. The restaurant already has 5 pints of cream in the fridge.
To find - How many more pints of cream will they need for the pasta?
Solution -
10 people = 3 cups of cream
⇒80 people = 8×3 = 24 cups of cream
Now,
We know that,
1 cup = 0.5 pints
⇒24 cup = 24×0.5 = 12 pints.
Now,
Given that, The restaurant already has 5 pints of cream in the fridge.
So,
Total pints more needed = 12 - 5 = 7 pints.
∴ we get
Total pints of cream will they need for the pasta = 7 pints
<u>Given</u>:
The system of linear equations are 
and 
We need to determine the solution to the system of equations using substitution method.
<u>Solution</u>:
The solution can be determined using the substitution method.
Let us substitute 
in the equation
Thus, we have;
Thus, the value of y is -17.
Substituting in the equation , we get;
Thus, the value of x is -13.
Hence, the solution to the system of equations is (-13,-17)
