Hello!
This equation seems a bit complicated, so to solve it, let's break it down using the PEMDAS order of operations.
P - Parenthesis
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
If we look at the equation, we can see that there is a number in parenthesis. However, it's only a number in parenthesis, and not an operation, hence, we can not apply PEMDAS to it. Let's skip parenthesis, and since there are no exponents or multiplication operations, move on to division.
-5.1 ÷ 1.5 = -3.4
Now let's move on to addition.
-5.872 - 3.4 = 2.472
2.472 is your answer.

Answer:
= −
1
3
1
Step-by-step explanation:
No real solutions because the discriminant is negative
The square root of a negative number is not a real number
Answer:
8/15
Step-by-step explanation:
Call the midpoint M. Then it must satisfy
... M = (R + S)/2
... 2M = R + S . . . . multiply the above equation by 2
... R = 2M -S . . . . . subtract S
Since we need to use this equation several times, it is convenient to calculate ...
... 2M = 2(6, -10) = (12, -20)
All we need to do is subtract the given value of S from this.
10. R = (12 -0, -20 -8) = (12, -28)
11. R = (12 -9, -20 -(-3)) = (3, -17)
12. R = (12 -(-2), -20 -(-7)) = (14, -13)
Answer:
The mean is to add up all the numbers then divide by how many there are.
Step-by-step explanation:
Therefore, 1+2+3+4+5=15
15÷5=3
it's 3
hope it helps :)
