Answer:
3
x
=
15
Step-by-step explanation:
you need to divide the 15 by 10, 3 times and the you will get five
and it says Determine which equations below have x = 15 as a solution.
We have to write the standard form of : two hundred ten million, sixty four thousand , fifty.
210 * 10,000,000 + 64 * 10,000 + 50
Answer:
The standard form is 210,064,050.
<h3>
Answer:</h3>
square units (approximately 2338.26859)
<h3>
Step-by-step explanation:</h3>
The formula for finding the area of a regular hexagon when you know its side length is
, where
is the area and
is the side length.
- Substitute in the side length.
![A=\frac{3\sqrt{3}*30^2}{2}](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B3%5Csqrt%7B3%7D%2A30%5E2%7D%7B2%7D)
- Simplify the exponent.
![A=\frac{3\sqrt{3}*900}{2}](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B3%5Csqrt%7B3%7D%2A900%7D%7B2%7D)
- Multiply.
![A=\frac{2700\sqrt{3}}{2}](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B2700%5Csqrt%7B3%7D%7D%7B2%7D)
- Divide.
![A=1350\sqrt{3}](https://tex.z-dn.net/?f=A%3D1350%5Csqrt%7B3%7D)
is as simple as the solution can get without estimating, but you can estimate with a calculator to find that it is approximately 2338.26859.
7x = -36+10x
X=12
You minus the 10 from 7 (7-10=-3) (-36/-3) gives you 12
