Answer:

15 1/12

Step-by-step explanation:

First step, add the whole numbers ie 6+8=14

Second, add fractions, 1/3+3/4

The lcm of denominators is 12 hence (4+9)/12=13/12=1 1/12

14+1 1/12=15 1/12

Graph each circle given below right the center and radius of each circle

expeople1 [14]

Answer:

Center: (-3,-2)

Radius: √6

The graph is attached.

Step-by-step explanation:

The equation of the circle has the form:

$(x -h)^{2}+(y-k)^{2}=r^{2}$

Where (h,k) is the point of the center of the circle and r is the radius of the circle.

The equation given in the problem is

$(x +3)^{2}+(y+2)^{2}=6$

Therefore:

h=-3

k=-2

The center is at (-3,-2)

And the radius is:

$r^2=6\\r=\sqrt{6}$

Then, you can graph it has you can see in the image attached.

1/6d + 2/3 = 1/4(d-2)

xxMikexx [17]

D = 14

1/6d + 2/3 = 1/4d - 1/2
2d + 4*2 = 3d - 6
2d - 3d = -6-8
-d = -14
d = 14

Need a quick answer please

Lesechka [4]

Answer:

AC = 38

Step-by-step explanation:

AB = BC

4 - 5x = 2x + 25

-7x = 21

x = -3

AC = 2(BC) = 2(2x + 25) = 4x + 50 = 4(-3) + 50 = -12 + 50 = 38

AC = 38
