Answer:
x = 21
Step-by-step explanation:
Multiply both sides by 16
3/4 x 16 = x - 9
2 Simplify 3/4 x 16 to 48/4
48/4 = x - 9
3 Simplify 48/4 to 12
12 = x - 9
4 Add 9 to both sides.
12 = x - 9
5 Simplify 12+9 to 21
21=x
6 Switch sides.
Answer: x=21
Y=-2x-6. B is the y intercept, so I think it would be -6 from the point.
5(n-4)=(4n-12)
First: Distribute 5 into n and -4.
5(n-4)=(5n)+(5*-4)= 5n-20.
Second: Subtract 4n from both sides to eliminate the variable from the right side of the equation.
(5n-20)=(4n-12)
n-20=-12
Next: Add 20 to both sides to eliminate the constant from the left side of the equation.
n-20=-12
n=8
The unknown number is 8.
You have to add them all together and times that by 60%, when you get 13.8 that's the answer and to prove it, subtract 23-13.8 and you get 9.2 and that's 40%
the volume is 2040 inches^3
