Answer:

x=2

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

Step-by-step explanation:

This is a linear equation, and we will need to get the variable by itself.

Let's calculate!

$8+3x=14\\3x=14-8\\3x=6$

Now we divide both sides by 3. Dividing 3 by 3 is just 1, and we don't need to write the 1, and 6 divided by 3 is two! So your equation will look like this:

$3/3x = 6/3\\x=2\\$

Hope that helps! :)

A and B are two similar shapes the area of shape A is 200cm2 calculate the area of shape B

barxatty [35]

Answer:

Area of shape B = 312.5 cm²

Step-by-step explanation:

Ratio of Area of A : Area of B = 12² : 15²

Given that area of A is 200 cm², let the area of shape B = x

Therefore:

200:x = 12²:15²

200/x = 144/225

Cross multiply

144x = 200*225

144x = 45,000

x = 45,000/144

x = 312.5 cm²

Area of shape B = 312.5 cm²

If f(x) and its inverse function, f^-1(x), are both plotted on the same coordinate plane, where is their point of intersection?

zloy xaker [14]

Answer:

Step-by-step explanation:

Their point of intersection, assuming there is one, will be somewhere on the line y = x. This line, y = x, is the line of symmetry between a function and its inverse. So if the two do in fact intersect, it will be at some point on that line

How many 2/3 pounds are in a sixth of a pound?

mote1985 [20]

None. ⅔ is greater than 1/6 but ⅔ equals 2 x (1/6).
Basically one half of ⅔ equals 1/6

A betta fish tank is in the shape of a cube. The volume of the fish tank is 216

GarryVolchara [31]

To find this answer, we need to understand how to get the Volume.

We get the volume by the formula: L x W x H

L = Length

W = Width

H = Height

So, we can see that there are 3 units required to know for getting the volume, if that's true, then, to do the inverse operation of finding the volume. That can be done by using thie formula:

$V=a^3$

a= edge

Solving for a

a=V⅓=216⅓=6

<h2>So hence, each of the Cube shaped Fish Tank is 6in³</h2>

now, let's look at how to find whether our answer is right or wrong

6x6=36

36x6=216

So hence, our answer is right!
