To solve an equation of the form a • bx = d, you should first divide both sides by the coefficient _____.

1 answer:

8 0

We have to isolate x on one side of the equation in order to solve the equation.
So, the very first step would be to divide both the sides by a.

This will leave us with:

bx = d/a

Next divide both sides by b to get x on the left hand side giving us the answer to the equation.

So, the answer to this question is "a"

Which is equivalent to √3/√8 when denominator is "rationalized"?

TEA [102]

Step-by-step explanation:

$\dfrac{\sqrt3}{\sqrt8}=\dfrac{\sqrt3\cdot\sqrt2}{\sqrt8\cdot\sqrt2}=\dfrac{\sqrt{3\cdot2}}{\sqrt{8\cdot2}}=\dfrac{\sqrt6}{\sqrt{16}}=\dfrac{\sqrt6}{4}$

$\sqrt{ab}=\sqrt{a}\cdot\sqrt{b}\ \text{for}\ a\geq0\ \wedge\ b\geq0\\\\\sqrt{a}=b\iff b^2=a\ \text{for}\ a\geq0\ \wedge\ b\geq0\\\\\sqrt{16}=4\ \text{because}\ 4^2=16$
