Alinara [238K]

Step-by-step explanation:

a= 16x+3-14x+15

combine like terms, 16x-14x= 2x

so,

2x+3+15,

15+3=18

18=2x, divide 18 by 2

x=9

b) *open the parenthesis* -1/6 *24x = -4x

-1/6*60 = -10

-4x- (-10)= -4x+10

-4x+10+2x= -4x+2x= -2x

-2x=10 = 2x=-10 = x=-5

Cheers!

Answer:

Option (4).

Step-by-step explanation:

Outer diameter of the hollow metallic ball = 10 centimeters

Outer radius of this ball = $\frac{10}{2}$ = 5 cm

Volume of the outer ball $V_{1}$ = $\frac{4}{3}\pi (r)^3$

= $\frac{4}{3}\pi (5)^3$

Inner radius of the hollow metallic ball = (5 - 1) = 4 cm

Volume of the inner hollow ball $V_{2}$ = $\frac{4}{3}\pi (4)^3$

Volume of the metal used in the metallic ball = $V_{1}-V_{2}$

= $\frac{4}{3}\pi (5)^3-\frac{4}{3}\pi (4)^{3}$

= $\frac{4}{3}\pi [(5)^3-(4)^3]$

Therefore, expression given in option (4) will be used to measure the volume of the hollow metallic ball.
