Answer:
-5
Step-by-step explanation:
-2.5y + 8y - 10.5
= 5.5y - 10.5y
= -5y
The coefficient of the variable y is -5.
Hey there!
ORIGINAL EQUATION:
|x + 2| = 3
TRANSLATE:
x + 2 = 3 or x + 2 = -3
SOLVING for: x + 2 = 3
SUBTRACT 2 to BOTH SIDES
x + 2 - 2 = 3 - 2
CANCEL out: 2 - 2 because it give you 1
KEEP: 3 - 2 because help solve for the current x-value
NEW EQUATION: x = 3 - 2
SIMPLIFY IT!
x = 1
Thus, your answer is: x = 2
/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\
SOLVING for: x + 2 = -3
SUBTRACT 2 to BOTH SIDES
x + 2 - 2 = -3 - 2
CANCEL out: 2 - 2 because it give you 0
KEEP: -3 - 2 because it help solve for the current x-value
NEW EQUATION: x = -3 - 2
SIMPLIFY IT!
x = -5
Thus, your answer is: x = -5
/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\
Therefore, your answer is: x = 1 or x = -5
Good luck on your assignment & enjoy your day!

D. I would best guess, hey have a nice thanksgiving week. Hope they gave you a whole week of school out like mine did :) if you go to school
Answer:
n = (4 i)/sqrt(11) or n = -(4 i)/sqrt(11)
Step-by-step explanation:
Solve for n:
11 n^2 + 16 = 0
Subtract 16 from both sides:
11 n^2 = -16
Divide both sides by 11:
n^2 = -16/11
Take the square root of both sides:
Answer: n = (4 i)/sqrt(11) or n = -(4 i)/sqrt(11)
