What is the solution for x in the equation -4+5x-7=10+3x-2x in a fraction

Alex

Answer:

x = 21/4

Step-by-step explanation:

re-arrange the equation

-4+5x-7-3x = 10-2x (move 3x to the other side)

-4+5x-7-3x+2x = 10 (move 2x to the other side)

5x-7-3x+2x = 10+4 (move 4 to the other side)

5x-3x+2x = 10+4+7 (move 7 to the other side)

4x = 21 (add up both sides)

x = 21/4 (divide both sides by 4

Hello,

Step-by-step explanation:

Area of the sphere:

$S=4*\pi *r^2$

Volume of the sphere:

$V=\dfrac{4*\pi *r^3}{3}$

$\dfrac{S}{3} =\dfrac{V}{7} \\\\\dfrac{4*\pi *r^2}{3} =\dfrac{4*\pi *r^3}{3*7} \\\\1=\dfrac{r}{7} \\\\\\r=7\\\\great \ circle: 2*\pi* r=14*\pi\\$

$Volume=\dfrac{4*\pi *7^3}{3} =\dfrac{1372*\pi }{3} \approx{1436,7550...(cm^3)}$
