Answer:
n=3
Step-by-step explanation:
So the question we are to solve is to be solved by collecting like terms and by division
So let's solve the question
-5n+8=-7
So let's solve
-5n+8=-7
Substrate 8 from both sides
-5n=-15
So let's make n the subject of formula by dividing both sides by -5
n=3
Therefore the final answer for the given question is 3
Answer:
x = - 5/2 or x = - 3/2
Step-by-step explanation:
|-2(x+2|=1
|-2x-4|=1
- 2x - 4 = 1 or - 2x - 4 = - 1
- 2x - 4 = 1
- 2x = 4+1
x = - 5/2
or -2x - 4 = - 1
-2x = 4 - 1
x = - 3/2
3=−(−y+6)
Simplify:
3=−(−y+6)
3=y+−6(Distribute)
3=y−6
Flip the equation.
y−6=3
Add 6 to both sides.
y−6+6=3+6
y=9
let the number of sides be n.
Thus,
(n-2)x180=330
n-2=1.83
n=3.83
Rounding off we have, n=4.
Thus the total number of side is 4.
