The answer would be D
-1 3/7=-10/7
-3 2/3=-11/3
-10/7 x -11/3=110/21
110/21=5 5/21
A negative times a negative =a positive

Answer:
Total number of ways to select all sstudent to make assignment = 10×36×70×1 = 25200
Step-by-step explanation:
We have given number of students = 10
These 10 students are assigned to four dorm rooms a single, a double, a triple and a quad
So number of ways to assigned single student
Now left student = 10 -1 = 9
So number of ways to assigned double student
Now left student = 9-2 = 7
So number of ways to assigned triple student =70
Now left student = 7 - 3 = 4
So number of ways to assigned quad student
So total number of ways to select all sstudent to make assignment = 10×36×70×1 = 25200
Answer:
687.5
Step-by-step explanation:
To find the equivalent expression, simplify the operations using order of operations.
2.50(600 - 500*.25) - 500 Multiply -500*0.25
2.50(600 - 125) - 500 Subtract 600 - 125
2.50(475) - 500 Multiply 2.50(475)
1187.5 - 500 Subtract
687.5
So the variables has a clear casual right
