Solve for x:
3x + 2y = 3975
~Subtract 2y to both sides.
3x + 2y − 2y = 3975 − 2y
~Simplify
3x = 3975 − 2y
~Divide 3 to both sides
3x/3 = 3975-2y/3
x = 1,375 - 2/3
------------------------------------------------
Solve for y:
3x + 2y = 3975
~Subtract 3x to both sides.
3x + 2y − 3x = 3975 − 3x
~Simplify
2y = 3975 − 3x
~Divide 2 to both sides
2y/2 = 3975-3x/2
~Simplify
y = 3975/2 - 3x/2

Sorry if i get it wrong
The ordered list from least to greatest using the absolute values would be: |-1 1/8|, |-1.5|, |-2 1/2|, |-2.4|, |-3|.
The student is asking to order a series of numbers from least to greatest. The numbers given are in absolute values. Absolute value refers to the distance of a number from zero, disregarding whether it is negative or positive. Therefore, the |-2.4| signifies the absolute value of -2.4, which is 2.4. Similarly, the other numbers convert to 1.5, 2.5, 3, and 1.125 respectively.
To answer this question, we must understand that the smaller the absolute value, the closer the number is to zero. Hence, the order from smallest (or least) to largest (or greatest) would be: |-1 1/8|, |-1.5|, |-2 1/2|, |-2.4|, |-3| .

In a recent golf match, Tiger’s score was 4 less than Phil’s score. Their combined scores totaled 140. Let p represent Phil's score and t represent Tiger's score.
Which pair of equations can be used to determine their scores?
A. p – t = 140
p + t = 4
B. p + 140 = t
p = 4
C. p + t = 140
p – t = 4
D. p + t = 140
p + t = 4
(i think this one is C)

Allison and her husband Noah both get in their cars and begin to drive at the same time. Allison starts 360 mi from their home and drives directly home at a constant rate of 50 mph. Noah starts at their home and drives away from the home at a constant rate of 40 mph. The system that models this situation is given, where d represents the distance from home, and t represents time, in hours. The solution to the system is (4, 160).
What is the correct interpretation of the solution to this system?
d = 360 - 50t
d =40t
A. Noah will be 160 mi from home and Allison will be 4 mi from home.
B. Allison and Noah will both be 160 mi from home after 4 h.
C. Noah will be 4 mi from home and Allison will be 160 mi from home.
D. Allison and Noah will both be 4 mi from home when they drive for 160 min.
