Answer:
yea
Step-by-step explanation:
Answer:
N(-2) = 
-5 this is also equal to n=2.5
Step-by-step explanation:
multiply both sides by 2
-4n = -2n-5
add 2n to both sides
-2n = -5
divide both sides by -2
n=2.5
Answer: Area of circular plate is 36.5 square inches
Step-by-step explanation:
The formula for determining the circumference of a circle is expressed as
Circumference = 2πr
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
From the information given,
Circumference of circular plate = 21.4 inches. Therefore
2 × 3.14 × r = 21.4
6.28r = 21.4
r = 21.4/6.28
r = 3.41 inches
The formula for determining the area of a circle is expressed as
Area = πr²
Area of circular plate = 3.14 × 3.41² = 36.5 square inches
Answer:
x = 3.67
Step-by-step explanation:
Simplify both expressions
14x - 18 = 5x + 15
Subtract the bigger (n)x by the smaller
14x - 5x = 9x
Plus the smallest by itself, giving you:
9x - 18 = 15
+18 +18
9x = 33
Simplify ( divided by 3 )
3x = 11
x = 3.67
