What is the solution to the equation below? Round your answer to two
ipn [44]

Answer:

<u>The correct answer is x = 7.05</u>

Step-by-step explanation:

1. Let's review the information given for answering the question:

7. 9x = 55.68

2. For solving the equation, we should proceed this way:

x = 55.68/7.9

x = 7.0481

<u>x = 7.05 (Rounding to two decimal places)</u>

<u>3. </u>Let's prove if the value of x is correct

7.9 * 7.05 = 55.68

55.69 = 55.68

<u>The value is correct because we rounded the value of x</u>

What is 3/tan(30°) in radical form? (meant to be a fraction)
Kitty [74]
\bf y=\cfrac{3}{tan(30^o)}\implies y=\cfrac{3}{\frac{sin(30^o)}{cos(30^o)}}\implies y=\cfrac{3}{\frac{\quad \frac{1}{2}\quad}{\frac{\sqrt{3}}{2}} }\implies y=\cfrac{3}{\frac{1}{2}\cdot \frac{2}{\sqrt{3}}}&#10;\\\\\\&#10;y=\cfrac{3}{\quad \frac{1}{\sqrt{3}}\quad }\implies y=\cfrac{3}{1}\cdot \cfrac{\sqrt{3}}{1}\implies y=3\sqrt{3}
