Answer:
<em>The student completed 13 courses worth 3 credits</em>
Step-by-step explanation:
<u>System of Equations</u>
Let's assign the following variables:
x = number of courses worth 3 credits
y = number of courses worth 4 credits
Some student completed 18 courses thus:
x + y = 18 [1]
The student earned a total of 59 credits:
3x + 4y = 59 [2]
From [1]:
y = 18 - x
Substituting in [2]:
3x + 4(18 - x) = 59
Operating:
3x + 72 - 4x = 59
Simplifying:
-x = 59 - 72 = -13
x = 13
The student completed 13 courses worth 3 credits
Answer:
The temperature at the end of the day is 2 degrees
Step-by-step explanation:
Here, we are interested in calculating the temperature at the end of the day.
In the question, we are told that at the beginning of the day, temperature was -14 degrees.
But throughout the day, the temperature increased by 16 degrees;
Thus, the temperature at the end of the day = -14 degrees + 16 degrees = 2 degrees
1 inch on the drawing represents 11 feet in the labyrinth middle school.
Step-by-step explanation:
Step 1:
The labyrinth middle school is much larger than the drawing. For 33 inches on the drawing, it is 363 feet on the actual school.
So 33 inches on the drawing is equal to 363 feet in the labyrinth school.
Step 2:
To calculate the scale factor, we divide the measurement after scaling by the same measurement before scaling.
In this case, the drawing that Tabitha drew is after scaling and the labyrinth middle school is the measurement before scaling
The scale factor 
So the scale factor is 
. This means that 1 inch on the drawing is 11 feet in the actual school.
