Answer with Step-by-step explanation:
Let x and y are two numbers
According to question
....(1)
Suppose x is larger than y
![x^2=x(4y+8x)](https://tex.z-dn.net/?f=x%5E2%3Dx%284y%2B8x%29)
![x=4y+8x](https://tex.z-dn.net/?f=x%3D4y%2B8x)
![x-8x=4y](https://tex.z-dn.net/?f=x-8x%3D4y)
![-7x=4y](https://tex.z-dn.net/?f=-7x%3D4y)
![y=-\frac{7}{4}x](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B7%7D%7B4%7Dx)
Substitute the value of y
![x^2+(-\frac{7}{4}x)^2=100](https://tex.z-dn.net/?f=x%5E2%2B%28-%5Cfrac%7B7%7D%7B4%7Dx%29%5E2%3D100)
![x^2+\frac{49}{16}x^2=100](https://tex.z-dn.net/?f=x%5E2%2B%5Cfrac%7B49%7D%7B16%7Dx%5E2%3D100)
![\frac{16x^2+49x^2}{16}=100](https://tex.z-dn.net/?f=%5Cfrac%7B16x%5E2%2B49x%5E2%7D%7B16%7D%3D100)
![\frac{65}{16}x^2=100](https://tex.z-dn.net/?f=%5Cfrac%7B65%7D%7B16%7Dx%5E2%3D100)
![x^2=\frac{16\times 100}{65}](https://tex.z-dn.net/?f=x%5E2%3D%5Cfrac%7B16%5Ctimes%20100%7D%7B65%7D)
![x=\sqrt{\frac{1600}{65}}=\frac{40}{\sqrt{65}}=\frac{40}{65}\sqrt{65}=\frac{8}{13}\sqrt{65}](https://tex.z-dn.net/?f=x%3D%5Csqrt%7B%5Cfrac%7B1600%7D%7B65%7D%7D%3D%5Cfrac%7B40%7D%7B%5Csqrt%7B65%7D%7D%3D%5Cfrac%7B40%7D%7B65%7D%5Csqrt%7B65%7D%3D%5Cfrac%7B8%7D%7B13%7D%5Csqrt%7B65%7D)
![y=-\frac{7}{4}\times \frac{8}{13}\sqrt{65}=-\frac{14}{13}\sqrt{65}](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B7%7D%7B4%7D%5Ctimes%20%5Cfrac%7B8%7D%7B13%7D%5Csqrt%7B65%7D%3D-%5Cfrac%7B14%7D%7B13%7D%5Csqrt%7B65%7D)
Answer: 4.87 x 10^9 is greater than 9.212 *10^8
Step-by-step explanation:
4.87 x 10^9 is greater than 9.212 *10^8 because it has the greater exponent.
4.87 * 10^9 = 4,870,000,000
9.212 *10^8= 921,200,000
4,870,000,000 > 921,200,000
Answer:
see below
Step-by-step explanation:
4(5n-7)+10n+2
Distribute
20n -28 +10n+2
Combine like terms
30n-26
Assuming you meant =
4(5n-7)=10n+2
Distribute
20n -28 =10n+2
Subtract 10n from each side
20n-10n-28 = 10n-10n+2
10n-28 =2
Add 28 to each side
10n-28+28=28+2
10n=30
Divide by 10
10n/10 =30/10
n=3
9(x+3)=4x-3
Distribute
9x+27 = 4x-3
Subtract 4x from each side
9x-4x+27 = 4x-4x-3
5x +27 =-3
Subtract 27 from each side
5x+27-27 = -3-27
5x = -30
Divide by 5
5x/5 = -30/5
x=-6
2(12-8x)=x-11x
Combine like terms
2(12-8x) = -10x
Divide by 2
12-8x = -5x
Add 8x to each side
12-8x+8x = -5x+8x
12 = 3x
Divide by 3
12/3 =3x/3
4=x
