X=27 Hope this helps!

1. Move the constant to the right-hand side and change its sign: root2x+10=2+6
2. Add 2+6: root2x+10=8
3. Square both sides of the equation: 2x+10=64
4. Move the constant to the right-hand side and change its sign: 2x=64-10
5. Subtract 64-10: 2x=55
6. Divide both sides of the equation by 2: 54 divided by 2=27
so this means X=27

The mass of a block of stone is 6400 kg. If the block has a volume of 0.8 m cubed, what is its density? Remember, density is mas

vovangra [49]

The question is asking for mass/unit of volume.
Therefore the density of the material would be 6400kg/0.8m^3. You then want to change the bottom into a 1 by multiplying the top and bottom both by 10/8. You now have 8000kg/m^3, which is the solution.

$8000 \frac{kg}{m^3}$

Add and simplify the following 3/8 + 9/28

SIZIF [17.4K]

Convert to a common denominator. Let's use 56. 3/8 = 21/56 and 9/28 = 18/56.

21/56 + 18/56 = 39/56

answer is 39/56

Answer:

Step-by-step explanation:

If you rearrange the equation in b, you get

y=5(x-3)+15

This means that your f(1) is equal to f(3), or 15, and for each additional month, it increases by 5, which is what the table shows.

I need to solve for X btw they are same side interior ( supplementary angles )

Sidana [21]

Answer:

x = 17.2

Step-by-step explanation:

since they are supplementary, when you add then together they equal 180

4x + 8 + 6x = 180

Combine like terms

10x + 8 = 180

subtract 8 from both sides

10x = 172

divide each side by 10

x = 17.2

hope this helps :)
