Hello!

OC = OD = Radius
6x + 2 = 10x - 16
6x - 10x = -16 - 2
-4x = -18
x = -18/-4
x = 4.5

Radius = OC = 6(4.5) + 2 = 29 units

Set OC and OD equal to each other.

6x + 2 = 10x - 16

Combine like terms by moving them over.

Subtract 2 from both sides.

6x = 10x - 18

Subtract 10x from both sides.

-4x = -18

Divide both sides by -4 to get x.

x = 4.5

Substitute 4.5 in for x.

6(4.5) + 2 = 10(4.5) - 16

27 + 2 = 45 - 16

29 = 29

The radius of circle O is 29.

Answer:

$x=45$

Step-by-step explanation:

The angle sum of a pentagon is 540°

Using this and the angles we know, we can create an equation.

$90+148+112+x+3x+10=540 \\ \\ 360+4x=540 \\ \\ 4x=180 \\ \\ x=45$

The average cost per unit C(x), in dollars, to produce x units of toy cars is given by C(x)=(8000)/(x−50)C(x)=(8000)/(x−50). Wha

podryga [215]

$C(x)= \frac{8000}{x-50}$

gives an average cost per unit, if we want to produce x of them.

So for example, we want to produce 500 toy cars for our store, and we need a price per unit (per 1 toy car). What we do is we calculate C(500).

So to calculate the cost of one unit when producing 1250, we calculate C(1250)

$C(1250)= \frac{8000}{1250-50}= \frac{8000}{1200}=6.67$ $ is the cost of 1 toy car.

Answer:

Tina

Step-by-step explanation:

bc if you sub in 4 for x the equations on both sides are 0

check:

-4 + 4 = 0 -3 x 4 = -12

0 x 3 = 0 12 + -12 = 0

0 = 0

please mark this as brainiest!!!!
