What is the answer to 3x+x/4=x+3/4

erica [24]

Answer:x = 1

Step-by-step explanation:

3x + x/4 = x + 3/4

Subtract x from each side

2x + x/4 = 3/4

Times each side by 4

The 4 beneath the x cancels out

3/4 x 4 = 3

2x + x = 3

3x = 3

Divide each side by 3

x = 1

The sine of angle θ is 0.3.<br><br> What is cos(θ)?

Sergio [31]

The answer:

$\sqrt{9}1 /10$

Explanation to your question:

Since the sin of theta is 0.3, we can reasonably deduct that the opposite side to theta has a ration of 3 to 10 to that of the hypotenuse. Thus, the adjacent side to theta, using the pythagorean theorem, will be root91. Therefore, since the cosine of theta is the adjacent/hypotenuse, we get root 91/10
