Answer:
0.14
Step-by-step explanation:
1/7 = 0.142
Since 2<5 the answer is 0.14.
20 - 12 = x
combine like terms, theres ur answer
Infinitely many solutions, you need to do the distributive property.
The answer of 4(2x^3 y^4 )^4/2(2x^2 y^6 )^3 after simplification will be
4 ![x^{6} y^{-2}](https://tex.z-dn.net/?f=x%5E%7B6%7D%20%20y%5E%7B-2%7D)
Step-by-step explanation:
To simplify
.
Using exponential law the exponents of variables will be added when multiplied as per rule
we get
![\frac{4[(2^4)(x^{3\times 4}) ( y^{4\times4} )] }{2[(2^3)(x^{2\times3} ) (y^{6\times3} )]}\\](https://tex.z-dn.net/?f=%5Cfrac%7B4%5B%282%5E4%29%28x%5E%7B3%5Ctimes%204%7D%29%20%28%20y%5E%7B4%5Ctimes4%7D%20%29%5D%20%7D%7B2%5B%282%5E3%29%28x%5E%7B2%5Ctimes3%7D%20%29%20%28y%5E%7B6%5Ctimes3%7D%20%29%5D%7D%5C%5C)
![\frac{4[(16)(x^{12}) ( y^{16} )] }{2[(8)(x^{6} ) (y^{18} )]}\\\\\frac{64x^{12}y^{16} }{16 x^{6}y^{18} }](https://tex.z-dn.net/?f=%5Cfrac%7B4%5B%2816%29%28x%5E%7B12%7D%29%20%28%20y%5E%7B16%7D%20%29%5D%20%7D%7B2%5B%288%29%28x%5E%7B6%7D%20%29%20%28y%5E%7B18%7D%20%29%5D%7D%5C%5C%5C%5C%5Cfrac%7B64x%5E%7B12%7Dy%5E%7B16%7D%20%20%7D%7B16%20x%5E%7B6%7Dy%5E%7B18%7D%20%20%7D)
Now by dividing according to exponential rule the exponents of variables will be subtracted as per rule
![(\frac{64}{16} ) x^{12-6} y^{16-18} \\4 x^{6} y^{-2}](https://tex.z-dn.net/?f=%28%5Cfrac%7B64%7D%7B16%7D%20%29%20x%5E%7B12-6%7D%20%20y%5E%7B16-18%7D%20%5C%5C4%20x%5E%7B6%7D%20y%5E%7B-2%7D)
So the answer of 4(2x^3 y^4 )^4/2(2x^2 y^6 )^3 after simplification will be
4 ![x^{6} y^{-2}](https://tex.z-dn.net/?f=x%5E%7B6%7D%20%20y%5E%7B-2%7D)

Answer: the right cost is $1.05 for a bat and 0.5c for a ball.
Step-by-step explanation:
Let's imagine x in the price of bat and y is the price of the ball
From the infor we know that:
x + y= 1.10 (dollars)
and since the bat is $1 more than the ball we can ensure that:
x - 1 = y
Now we can replace y as follow:
x + x - 1 = 1.10
2x - 1 = 1.10
2x = 1.10 + 1
2x = 2.10
x= 2.10/2= 1.05 (dollars)
