Expand

6 - 3x + 15 = 5x - 11

Simplify 6 - 3x + 15 to -3x + 21

-3x + 21 = 5x - 11

Add 3x to both sides

21 = 5x - 11 + 3x

Simplify 5x - 11 + 3x to 8x - 11

21 = 8x - 11

Add 11 to both sides

21 + 11 = 8x

Simplify 21 + 11 to 32

32 = 8x

Divide both sides by 8

32/8 = x

Simplify 32/8 to 4

4 = x

Switch sides

x = 4

Answer:

4=x

Step-by-step explanation:

6-3(x-5)=5x-11

Distribute the -3

6 -3x +15 = 5x -11

Combine like terms

21 -3x = 5x-11

Add 3x to each side

21-3x+3x = 5x+3x-11

21 = 8x-11

Add 11 to each side

21+11 = 8x-11+11

32 = 8x

Divide by 8

32/8 = 8x/8

4 =x

60-9 =51

51-4 =47

Step-by-step explanation:

the farmer has 12 chickens and each chicken laid 5 eggs which is 12×eggs laid(5) = 60

he thre away 9 eggs which means that we are going to subtract 9 from 60

Volume Formula [Cylinder]:
$\displaystyle V = \pi r^2 h$

r is radius
h is height

Step-by-step explanation:

Step 1: Define

Identify given variables.

h = 5 cm

r = 10 cm

Step 2: Find Volume

[Volume Formula - Cylinder] Substitute in variables:
$\displaystyle V = \pi (10 \ \text{cm})^2 (5 \ \text{cm})$
[Order of Operations] Evaluate:
$\displaystyle V = 500 \pi \ \text{cm}^3$
Approximate:
$\displaystyle V \approx \boxed{ 1570.8 \ \text{cm}^3 }$
