$x -16=6x+4$
First you would move -16 to the other side by adding it.
$x = 6x + 20$
Then you would move 6x to the other side, by subtracting 6×
$- 5x = 20$
Then you would divide by -5 to get x by itself and solve.
$x = - 4$

uranmaximum [27]

Answer:

1.875\pi square units

Step-by-step explanation:

We know that area of a circle is pi r square.

The sector has a proportional area according to the angle it subtends at the centre.

Here we have a circle of radius 3 inches with central angle 75 degrees.

Total angle of a circle = 360

Area of the given sector = Area of yellow shaded= $\frac{75}{360} *\pi (3^2) \\= 1.875\pi$

Suppose cos(O) = 12/13, Quadrant I. Find sin(O).<br> A:13/12<br> B:5/13<br> C:13/5<br> D:5/12

noname [10]

Answer:

B: 5/13

Step-by-step explanation:

pythagoras theorem: a^2 + b^2 (sides) = c^2 (hypotenuse)

a^2 + 12^2 = 13^2

a^2 + 144 = 169

a^2 = 25

a = 5

sin = opp/hyp

sin 5/13
