Answer: x = 1

Step-by-step explanation: When we have this kind of setup, we want to put our variables together on one side of the equation and our numbers together on the other side of the equation.

So first, let's put our variables together on the left side

by subtracting 2x from both sides of the equation.

That gives us 3x + 9 = 12.

Now we can move our numbers to the right by

subtracting 9 from both sides and we get 3x = 3.

Now divide both sides by 3 and <em>x = 1</em>.

What is the slope-intercept form of 4x+5y=10

Annette [7]

Answer: The slope intercept form is y= -4/5 + 2

Step-by-step explanation:

4x +5y = 10

-4x -4x

5y= 10- 4x divide both sides by 5

y= 2-4/4x write this in slope intercept form

y= -4/5 + 2

Bubble wrap sells in sheets, and each sheet has 1 million individual spherical bubbles, each with a diameter of 0.01 m. What is

Triss [41]

Answer: The total volume of air contained in the bubbles of one sheet of bubble wrap is about 0.5 cubic meters.

Step-by-step explanation:

Volume of sphere :-

$V=\dfrac{4}{3}\pi r^3$ , where r is the radius of the sphere.

Given : Diameter of the bubble = 0.01 m

Then Radius of the bubble = $\dfrac{0.01}{2}=0.005\ m$

Volume of each bubble:-

$V=\dfrac{4}{3}(3.14) (0.005)^3$

Also, Number of bubbles in each sheet = 1,000,000

Then , the total volume of air contained in the bubbles of one sheet of bubble wrap will be :-

$\dfrac{4}{3}(3.14) (0.005)^3\times1,000,000=0.52333333\approx0.5\ \text{cubic meters}$

Hence, the total volume of air contained in the bubbles of one sheet of bubble wrap is about 0.5 cubic meters.
