Expression: 3(x - 5) = 21

= 3x - 15 = 21

= 3x = 21 + 15

= 3x = 36

= x = 36/3

= x = 12

In short, Your Answer would be: 12

Hope this helps!

Carmen is simplifying the expression (6. 21 0. 93) 0. 7. She recognizes that 0. 93 and 0. 07 will combine to equal 1, so she wou

To solve the problem w must know about the Associative property.

<h2>Associative property</h2>

The associative property states that the addition of the sum of two numbers (a,b) and a third number(c) is equal to the addition of the sun of the last two numbers(b, c) and the first number(a).

A+(B+C) = (A+B)+C

The property that will allow Carmen to do this without changing the value of the expression is the Associative property.

<h2>Explanation</h2>

Given to us

(6.21 + 0.93 ) + 0.07

<h3>Associative property.</h3>

Now, using Associative property,

(6.21 + 0.93 ) + 0.07

= 6.21 + (0.93 + 0.07)

=6.21 + (0.93 + 0.07)

Hence, the property that will allow Carmen to do this without changing the value of the expression is the Associative property.

timofeeve [1]

Answer:

The answer is 256 $in^{3}$ .

Step-by-step explanation:

To solve for the volume of the sphere, start by using the sphere volume formula, which is V = $\frac{4}{3} \pi r^{3}$ . However, in this formula, 3 will be used instead of ( $\pi$ ).
