Answer:

x = 4

Step-by-step explanation:

7x + 16/11 = 4

11 x 7x + 16/11 = 4 x 11

7x + 16 = 44

7x + 16 - 16 = 44 - 16

7x = 28

7x/7 = 28/7

x = 4

Check:

7x + 16/11 = 4

7(4) + 16/11 = 4

28 + 16/11 = 4

44/11 = 4

4 = 4 (note that this number is not the answer, just to check if each side is balanced, the actual answer is 4)

Bam !

Answer:

x = 4

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtract Property of Equality

Step-by-step explanation:

<u>Step 1: Define</u>

<u />\displaystyle \frac{7x + 16}{11} = 4<u />

<u />

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

  1. Multiply 11 on both sides:                    \displaystyle 7x + 16 = 44
  2. Subtract 16 on both sides:                  \displaystyle 7x = 28
  3. Divide 7 on both sides:                       \displaystyle x = 4

<u>Step 3: Check</u>

<em>Plug in x into the original equation to verify it's a solution.</em>

  1. Substitute in <em>x</em>:                    \displaystyle \frac{7(4) + 16}{11} = 4
  2. [Frac] Multiply:                    \displaystyle \frac{28 + 16}{11} = 4
  3. [Frac] Add:                          \displaystyle \frac{44}{11} = 4
  4. [Frac] Divide:                      \displaystyle 4 = 4

Here we see that 4 does indeed equal 4.

∴ x = 4 is the solution to the equation.

Let C be the circle (x-1)^2 + y-2)^2 =144 and P be point P(10,10). Which of the following is true?
oksian1 [2.3K]
First, an introduction:  If the equation of the circle were x^2 + y^2 = 144, then the center would be at (0,0) and the radius would be 12.  Note that the distance from the center to P(10,10) is 10sqrt(2), or 14.14.  Thus, in this example, P would be OUTSIDE the circle (since 14.14 is greater than the radius 12).

Now let's focus on <span>(x-1)^2 + (y-2)^2 =144.   Let x = 12 as an example; find the corresponding y:  9^2 + (y-2)^2 = 144, or    (y-2)^2 = 63, and so y-2 is approx. -8 or +8.  Then y (for x = 12) is either approx. -10 or 6:  (12,-10) or (12,6).  Are these inside the circle or outside?

A better way to address this would be as follows:

Find the distance from the center (1, 2) to the point P(10,10).  If this distance is less than 12, the point P is inside C; if greater than 12, P is outside C.

This distance is sqrt( (10-2)^2 + (10-1)^2 ), or sqrt (64+81) = sqrt(145).
This is LARGER than sqrt(144).  Thus, P is OUTSIDE the circle C.</span>
