Answer:
![x=22\frac{1}{2}=22.5](https://tex.z-dn.net/?f=x%3D22%5Cfrac%7B1%7D%7B2%7D%3D22.5)
Step-by-step explanation:
![x-9=\frac{3}{5}x](https://tex.z-dn.net/?f=x-9%3D%5Cfrac%7B3%7D%7B5%7Dx)
- First, lets get rid of the fraction. I did this by multiplying both sides by
.
![5(x-9)=5(\frac{3}{5}x)\\5x-45=\frac{5}{1} *\frac{3}{5}x\\5x-45=\frac{15}{5}x\\5x-45=3x](https://tex.z-dn.net/?f=5%28x-9%29%3D5%28%5Cfrac%7B3%7D%7B5%7Dx%29%5C%5C5x-45%3D%5Cfrac%7B5%7D%7B1%7D%20%2A%5Cfrac%7B3%7D%7B5%7Dx%5C%5C5x-45%3D%5Cfrac%7B15%7D%7B5%7Dx%5C%5C5x-45%3D3x)
- We want to isolate
on one side of this equation. Let's put any values with
on one side of the equation, and normal integers on the other.
![2x=45](https://tex.z-dn.net/?f=2x%3D45)
- Divide both sides by
.
![x=\frac{45}{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B45%7D%7B2%7D)
- If your teacher wants you to leave your final answer as an improper fraction, your final answer is this. If they want it to be a mixed number or decimal, your final answer will be:
![x=22\frac{1}{2}=22.5](https://tex.z-dn.net/?f=x%3D22%5Cfrac%7B1%7D%7B2%7D%3D22.5)
Answer:
y=-9/2x-10
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-1-8)/(-2-(-4))
m=-9/(-2+4)
m=-9/2
y-y1=m(x-x1)
y-8=-9/2(x-(-4))
y-8=-9/2(x+4)
y=-9/2x-36/2+8
y=-9/2x-18+8
y=-9/2x-10
<span>Disagree. A rational number is any number that can be written as a fraction of two integers. Tom wrote 3/47, and both 3 and 47 are integers. Just because the decimal has not yet terminated doesn’t mean that the number he is looking at is irrational.</span>
Original and bigger prism are similar with scale factor k = 4, so:
new surface area = k² * original surface area = 4² * 228 = 16 * 228 = 3648 m²
and
new volume = k³ * original volume = 4³ * 216 = 64 * 216 = 13824 m³
B I think we’ll hope this helps
