Answer:
Take the first two expressions (you can actually take any two expressions): $\frac{a+b-c}{c}=\frac{a-b+c}{b}$.
$\frac{a+b}{c}=\frac{a+c}{b}$
$ab+b^2=ac+c^2$
$a(b-c)+b^2-c^2=0$
$(a+b+c)(b-c)=0$
$\Rightarrow a+b+c=0$ OR $b=c$
The first solution gives us $x=\frac{(-c)(-a)(-b)}{abc}=-1$.
The second solution gives us $a=b=c$, and $x=\frac{8a^3}{a^3}=8$, which is not negative, so this solution doesn't work.
Therefore, $x=-1\Rightarrow\boxed{A}$.
Step-by-step explanation:
Answer:
1. z = -15
2. p = 7
3. h = -11
4. t = 14
5. q = 12
Step-by-step explanation:
1.
Add -1 both sides,
Multiply both sides by -5,
2.
Distribute 3 in 
and then add -6p and -6 both sides.
3.
Multiply both sides by 2,
Add -6h and 7 both sides,
4.
Add -3t and 3 both sides.
5.
Add -2q and 8 both sides.
Therefore,
1. z = -15
2. p = 7
3. h = -11
4. t = 14
5. q = 12
I can't make out what the radius of the sphere is, but the equation you're looking for is:
For example:
If the radius of a sphere is 5 m, it's volume would be,
The correct answer for this question is this one: "B. the quotient 5 cubed over 5 to the fourth, raised to the negative 3 power"
<span>A. 5 times the quotient 5 cubed over two-fifths, raised to the second power
B. the quotient 5 cubed over 5 to the fourth, raised to the negative 3 power
C. 5 to the negative 2 over 5 to the negative 5
E. 5 times the quotient 5 to the 5 over 5 cubed</span>
