Answer:
n = 2/3
Step-by-step explanation:
[9n-9]+10=7
Subtract 10 from each side
9n -9+10-10 =7-10
9n -9 = -3
Add 9 to each side
9n -9+9 = -3+9
9n = 6
Divide by 9
9n/9 = 6/9
n = 2/3

(e) What is the minimum average cost?

Answer:
The correct answer is D) 13%
Step-by-step explanation:
To turn a decimal into a percentage, we simply multiply by 100.
0.13 * 100 = 13%
Answer:
x=27.5
FG=72.5
GH=60
HF=47.5
Step-by-step explanation:
Sum of angles in a triangle=180
Therefore, FG+GH+HF=180
Substituting the values we have,
(3x - 10) + (2x+5) +(x+20) = 180
Collecting like terms
3x+2x+x = 180 +10 - 5 - 20
6x = 165
X= 27.5
FG = (3x - 10) = 3(27.5) - 10
FG= 72.5
GH= (2x+5) = 2(27.5)+5
GH=60
HF= x+20 =27.5+20
HF=47.5
