The value of x in 6x+7=3x+16
kozerog [31]

Answer:

x=3

Step-by-step explanation:

6x+7=3x+16

Subtract 3x from each side

6x-3x+7=3x-3x+16

3x+7 = 16

Subtract 7 from each side

3x+7-7 = 16-7

3x =9

Divide each side by 3

3x/3 = 9/3

x =3

A. How long does the piece of wire need to be to make the shape? Explain.
Misha Larkins [42]

A. The wire needs to be 138.226 cm long but already 34.5565 cm of the circle has been covered.

B. To determine the length of the wire needed, we subtract a quarter of the circles circumference from its whole circumference.

Step-by-step explanation:

Step 1:

The circumference of a circle is obtained by multiplying the radius with 2π.

The circumference of a circle = 2 \pi r.

Here the radius of the circle is 22 cm but already a quarter of the circumference has been covered with wire.

Step 2:

So to determine the length of the wire needed, we subtract a quarter of the circles circumference from its whole circumference.

So the circumference of the circle = 2(3.1415)(22) = 138.226 cm.

\frac{3}{4} (138.226) = 103.6695 cm and \frac{1}{4}(138.226) = 34.5565 cm.

So the wire needs to be 138.226 cm long but already 34.5565 cm of the circle has been covered. An additional 103.6695 cm of wire is needed to cover the remaining circle.

What is the value of x?<br><br> 2<br> 3<br> 6<br> 7
Romashka-Z-Leto [24]

Answer:

x = 2

Step-by-step explanation:

By the property of intersecting chords outside of the circle.

EC  \times ED = EB \times  EA \\ (x + 4)(x + 4 + 1) = (x + 1)(x + 1 + 11) \\ (x + 4)(x + 5) = (x + 1)(x + 12) \\  {x}^{2}  + (4 + 5)x + 20 =  {x}^{2}  + (1 + 12)x + 12 \\ 9x + 20 = 13x + 12 \\ 9x - 13x = 12 - 20 \\  - 4x =  - 8 \\ x =  \frac{ - 8}{ - 4}  \\  \huge \red{ \boxed{x = 2}}
