8x-19 = -12x+61 What is x?

olasank [31]

Answer:

x is 4

Step-by-step explanation:

Step one: Add 12x to both sides-

8x-19+12x=-12x+61+12x

20x-19=61

Step 2: add 19 to both sides

20x -19+19=61+19

20x=80

Step 3: divide both sides by 20

20x/20=80/20

x=4

Find the circumference of the circle 8.5cm

Vanyuwa [196]

Answer: The circumference of the circle is 53.38 cm.

Step-by-step explanation:

Circumference of the circle is the distance around the circle.

Formula used:

$C = 2\pi r$

Where,

C is circumference of circle

r is radius of circle

Given:

Radius of circle = 8.5 cm

Now putting all the given values in the above formula, we get:

$C = 2\pi r\\C=2\times 3.14\times 8.5cm\\C=53.38cm$

Therefore, the circumference of the circle is 53.38 cm.

If u help me your dreams will come true ya know

wariber [46]

Answer:

Area of larger circle = $\pi *r^2=3.14(11^2)=379.94$

Area of smaller circle = $\pi *r^2=3.14(3^2)=28.26$

Probability that it lands in the shaded area (smaller circle):

28.26 ÷ 379.94 = 0.07438... = 0.07 (nearest hundredth)
