Answer:
0.9
Step-by-step explanation:
0.7*(1.5 + y) = 3.5y - 1.47
or, (0.7*1.5) + 0.7y = 3.5y - 1.47
or, 1.05 + 1.47 = 3.5y - 0.7y
or, 2.52 = 2.8y
or, y = 2.52/2.8
or, y = 0.9

Answer:
B) ![\sqrt[4]{80} ^x](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B80%7D%20%5Ex)
Step-by-step explanation:
The given expression is 
It is 4th root. because 1/4 represents the 4th root.
So, ![\sqrt[4]{80} ^x](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B80%7D%20%5Ex)
Therefore, the answer is B) ![\sqrt[4]{80} ^x](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B80%7D%20%5Ex)
