Step-by-step explanation:
The scientific notation:

<em>1 ≤ a < 10</em> and <em>k -</em><em> any integer number</em>
<em />

The answer is a = 3/4 = 0.75
First get rid of the paranthesis,

Then set the denominators equal:

Then remove the denominators and solve:

Eliminate -12a^2 by adding 12a^2 to both sides:

Take the fourth root of them or take the square root twice:
![\sqrt[4]{256 {a}^{4} } = \sqrt[4]{81} \\ 4a = 3](https://tex.z-dn.net/?f=%20%5Csqrt%5B4%5D%7B256%20%7Ba%7D%5E%7B4%7D%20%7D%20%20%3D%20%20%5Csqrt%5B4%5D%7B81%7D%20%20%20%5C%5C%20%204a%20%3D%203)
Divide both sides by 4:
Y = 6/3x - 2
Just move x to the other side,
y - 6/3x = -2
Multiply by -1,
6/3x - y = 2
In short, Your Answer would be 6/3x - y = 2 or 2x - y = 2
Hope this helps!
Answer: 3 * n = 15
5 students tried out for the baseball team.
Step-by-step explanation:
n is the amount of kids who tried to try out for the baseball team.
15 kids tried out for the hockey team, and that’s 3 times as many as the amount who tried out for the baseball team, so 3 times n = 15, or 3 * 5 =15
hope this helped!
