Which of the following describes the correct process for solving the equation 2x + 6 = 22 and arrives at the correct solution? (

1 point)
Select one:
a. Divide both sides by 6 and then add 2. The solution is x = 8.
b. Subtract 6 from both sides and then divide by 2. The solution is x = 8.
c. Add 6 to both sides of the equation and then divide by 2. The solution is x = 6.
d. Subtract 6 from both sides of the equation and then divide by 22. The solution is x = 16.

You would subtract 6 from both sides and then divide by 2. So the solution would be x=8. So 'B'

( !!!!! )
Lyrx [107]
Answer: Cylinder 1 - 25.1327412283 cubic cm
Cylinder 2 - 100.5309469149 cubic cm
Cylinder 3 - 226.1946710585 cubic cm

For each of the cylinders, we will need to use the same formula, h(pi(r squared)).

Cylinder 1 - 8(pi(1 squared)). 1 squared = 1. pi × 1 = 3.1415926536. 3.1415926536 × 8 = 25.1327412283 cubic cm.

Cylinder 2 - 8(pi(2 squared)). 2 squared = 4. 4 × pi = 12.5663706144. 12.5663706144 × 8 = 100.5309469149 cubic cm.

Cylinder 3 - 8(pi(3 squared)). 3 squared = 9. 9 × pi = 28.2743338823. 28.2743338823 × 8 = 226.1946710585 cubic cm.

- Hope it helps!

The two solids are similar and the ratio between the lengths of their edges is 2:7 what is the ratio of their surface areas?
vovangra [49]

Answer:

The ratio of their surface areas is \frac{4}{49}

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal and this ratio is called the scale factor

In this problem the scale factor is equal to the ratio \frac{2}{7}

and

Remember that

If two figures are similar, then the ratio of its surface areas is equal to the scale factor squared

therefore

In this problem the ratio of their surface areas is (\frac{2}{7})^{2}=\frac{4}{49}

Segments in Circles<br><br><br> TW=3, CW=x, TU=x+7, VW=6. Find the value of x.
Kryger [21]

Answer:

x=2

Step-by-step explanation:

The diagram is attached below

  • TW=3
  • CW=x
  • TU=x+7
  • VW=6

TU=TW+WU

x+7=3+WU

WU=x+7-3

WU=x+4

To determine the value of x, we apply the theorem of intersecting chords.

TW X WU = CW X WV

x(x+4)=6 \times x\\x^2+4x=6x\\x^2=6x-4x\\x^2=2x\\$Divide both sides by x\\x=2
