Answer:

Step-by-step explanation:

x + 4 = 9

Subtract 4 from both sides of the equation since 4 and 9 are like terms.

x + 4 = 9

- 4 -4

This will leave you with x = 5.

Answer:

<h2>You have to isolate x to find the answer. To do this you take your equation and multiply both sides of your equation by negative four. x−4=9 then becomes x−4×−4=9×−4 . As a final result you obtain x=−36</h2>

sweet-ann [11.9K]

Answer: The volume of given substance is $2.2 cm^{3}$ .

Step-by-step explanation:

Given: Density = 10.7 $g/cm^{3}$

Mass = 23.54 g

Density of a substance is the mass of substance divided by its volume.

Mathematically, $Density = \frac{mass}{volume}$

Substitute the values into above formula to calculate volume as follows.

$Density = \frac{mass}{volume}\\10.7 g/cm^{3} = \frac{23.54 g}{volume}\\volume = \frac{23.54 g}{10.7 g/cm^{3}}\\= 2.2 cm^{3}$

Thus, we can conclude that the volume of given substance is $2.2 cm^{3}$ .

Vlad1618 [11]

Answer:

99 in³

Step-by-step explanation:

Let the radius and height of each be r and h in. respectively.

Write an equation for the volume of cone.

Volume of cone= ⅓πr²h

⅓πr²h= 33

Multiply both sides by 3:

πr²h= 99

Volume of cylinder= πr²h

We have found the value of πr²h previously, which is 99.

Thus, the volume of the cylinder is 99 in³.
