The system of equations are:
2x − 4y = 6
−3x + 3y = 9
To eliminate x, you should:
1. multiply first equation with 3
2. multiply second equation with 2
3. add the new equations you got
So your answer is A.
The pints of ice cream for the students is an illustration of metric units
Nadia needs 12 pints of ice cream for the 24 students
<h3>How to determine the pints of ice cream?</h3>
The given parameter is:
Students = 24
She needs one cup for each student in the class.
So, the number of cups needed is:
Cups = 24
1 cup makes 1/2 pint.
So, we have:
Pint = 1/2 * 24
Pint = 12
Hence, Nadia needs 12 pints of ice cream for the 24 students

Answer:
73 degrees.
Step-by-step explanation:
So, let's see the information provided in the question.
At 8 AM, the thermometer was reading -5 degrees.
At 12:30 PM, the temperature has increased by 11 degrees, so it's now +6 degrees outside.
Inside Susan's house, the temperature is 7 degrees more than 11 times the outside temperature, at 12:30 PM.
So, we know the outside temperature at 12:30 PM is +6 degrees.
11 times 6 = 66 degrees.
Then we add the additional 7 degrees, to get a total of 73 degrees.
Answer:
Step-by-step explanation:
Answer:
2.5x+0.75y=933
x+y=747
Step-by-step explanation:
x= number of cheese sandwiches
y= number of soft drinks
first equation: 2.5x+0.75y=933
**this is representing the cost of the drinks and sandwiches
second equation: x+y=747
**because x and y are the NUMBER of soft drinks and sandwiches, they both have to toal up to 747.
