Answer:

6 5/8

Step-by-step explanation:

You need to add 2 3/4 and 3 7/8

2 3/4 as an improper fraction is 11/4 and 3 7/8 as an improper fraction 31/8

To add them you need to have common denominators

So you multiply 11/4 by 2/2 which is 22/8

Now you can add them

22/8+31/8 = 53/8

53/8 = 6 5/8

What is 0.24x − 1.85 3.09 − 2.33x = 1.71

Law Incorporation [45]

Was the variable "y" supposed to be part of this equation? If so, perhaps you meant to share the following:

 0.24x − 1.85y = 3.09
− 2.33x = 1.71y

Plese, go back and reread the original question, and then ensure you have shared that question here precisely as it was presented.

Find the volume of this sphere. Use 3 for TT. V [?]in3 V = Tr3 8 in

frutty [35]

Answer:

The volume of the sphere is 2048 in³.

Step-by-step explanation:

The volume of a sphere is given by:

$V = \frac{4}{3}\pi r^{3}$

Where:

r: is the radius = 8 in

Having the radius and by using 3 for π, the volume is:

$V = \frac{4}{3}*3 (8 in)^{3} = 2048 in^{3}$

Therefore, the volume of the sphere is 2048 in³.

I hope it helps you!

Line 1 to 2: Commutative Property of Multiplication, because all that changed was the order of the things being multiplied.
Line 2 to 3: Commutative Property of *Addition*, because all that changed was the order of the things being added.

All that changed in either step was the ordering of the things being multiplied or added. That’s the commutative property.
