12 is the value of 8x-4 when 16x-2=30
16x - 2 = 30
+ 2 +2
16x = 32 , x=2
Substitute :
8x - 4 = 8(2) - 4 = 16-4 = 12!

Answer:

12

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define 1st equation</u>

16x - 2 = 30

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Add 2 on both sides:                    16x = 32
  2. Divide 16 on both sides:               x = 2

<u>Step 3: Solve equation</u>

  1. Define:                    8x - 4
  2. Substitute:              8(2) - 4
  3. Multiply:                  16 - 4
  4. Subtract:                 12

And we have our final answer!

What is the value of
Lisa [10]

Answer:

Please let me know if my calculations were incorrect. I am very sorry but unfortunately, your answer will be negative and not a whole number. None of the answers fit. It is either that I made a mistake or there is something wrong with the question.

Step-by-step explanation:

\frac{103*10-5*1010}{106} \\\frac{1030-5050}{106} \\\frac{-4020}{106} \\\\\frac{-2010}{53}

Consider the cylinder below. Which statements are true?
kari74 [83]

Answer:

A and C

Step-by-step explanation:

The volume of a cylinder is the area of a circle times the height.

\pir^{2}h

A = Plugging things in we'd have \pi 8^{2} 12. Which is pi x 64 x 12. Which is pi x 768. Which is 768 pi.

Basically use the same method for the other two questions

Find an equation of the circle that has center (6, 2) and passes through (-2,-6).
Irina18 [472]

Answer:

(x - 6)² + (y - 2)² = 128

Step-by-step explanation:

Given as the circle has center ( 6 , 2)

and it passes through points (-2 , -6)

Now , standard equation of circle is (x -a)² + (y- b)² = r²   , where (a , b) is center and r is the radius .

Again from given center the circle equation is

(x- 6)² + (y- 2)² = r²

Now this circle passes through points (-2 , -6)

so, (-2 -6)² + (-6 -2)²  = r²

so, 8²  + 8² = r²

Or, 128  = r²

i.e Radius pf this circle = 8\sqrt{2}

Hence the circle equation formed is

(x- 6)² +( y-2)² = 128   Answer
