There are 16 girls and 20 boys....the ratio of girls to boys is 16/20 which reduces to 4/5 or 4:5 or 4 to 5.
Answer:
d) y z x-2 + 3
Step-by-step explanation:
The root of every order of 1 is still 1, in other words, we have
![\sqrt[n]{1}=1](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7B1%7D%3D1)
So, if we evaluate the function at 1, we have
![\dfrac{\sqrt{1}-1}{\sqrt[3]{1}}-1 = \dfrac{0}{1}-1 = 0-1 = -1](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Csqrt%7B1%7D-1%7D%7B%5Csqrt%5B3%5D%7B1%7D%7D-1%20%3D%20%5Cdfrac%7B0%7D%7B1%7D-1%20%3D%200-1%20%3D%20-1)
Simply ,
5
Since the product of the square root of 5 ,
Gives 5
Therefore x is also equal to 5
15 is the answer it is correct can
