So, I'll do a few examples.

Ex 1: -5+3=?

Because the Commutative Property of Additon states that a+b=b+a (ex: 3+7=7+3), we can reorganize the statment.

So, -5+3 could also be 3+(-5) or 3-5.

Then, do simple math.

3-5=-2

Ex 2: -3+9=?

Use the Commutative Property of Addition again.

-3+9 is also 9-3.

More simple math.

9-3=6

Do you mean like -19+8=? or what? Be more specific.

I'm trying to find the molar mass though.

What is the number?

8x−3=5+4y

Solve for y:

Add 3 to both sides.

8x=4y+8

Divide both sides by 8.

x=1/2y+1

Plug into equation.

8(1/2y+1)-3=5+4y

Distribute.

4+8-3=5+4y

Combine like items.

4=4y

Divide both sides by 4.

y=1

What are you solving for?

Thanks

K thanks dude!

2 Feet by 3 Feet by 4 Feet

Use the formula for volume which is Length x Width x Height

L*W*H = 2*3*4 = 24 Ft³

When you divide 5.2 x 10-3 by 3.4 x 10-6 the answer is:

5.2*10 = 52

52-3 = 49

3.4*10 = 34

34-6 = 28

49/28 = 7/4 = 1.75
