Answer:

Only option E is equivalent to 5x+6=-8x-18.

Step-by-step explanation:

Given the expression

(5x+6) over 2 = 3-(4x + 12)

Let us simplify the expression

\frac{\left(5x+6\right)}{2}=3-\left(4x+12\right)

Multiply both sides by 2

\frac{5x+6}{2}\cdot \:2=3\cdot \:2-\left(4x+12\right)\cdot \:2

5x+6=6-\left(4x+12\right)\cdot \:2

Expand -(4x + 12) = -4x - 12

5x+6=-8x-18

Thus, option E is equivalent to 5x+6=-8x-18.

Further solving

5x+6=-8x-18

Add 8x from to both sides

5x+8x=-8x-24+8x

Simplify

13x=-24

Divide both sides

\frac{13x}{13}=\frac{-24}{13}

Simplify

x=-\frac{24}{13}

Thus, only option E is equivalent to 5x+6=-8x-18.

Seven less than the product of a number n and 1/6 is no more than 94
antiseptic1488 [7]

Answer:

  • n ≤ 606

Step-by-step explanation:

<u>Seven less than the product of a number n and 1/6 is no more than 94, translating:</u>

  • n*1/6 - 7 ≤ 94

<u>Solving for n:</u>

  • n/6  ≤ 94 + 7
  • n/6 ≤ 101
  • n ≤ 101*6
  • n ≤ 606

Each of the following data sets has a mean of x = 10. (i) 8 9 10 11 12 (ii) 7 9 10 11 13 (iii) 7 8 10 12 13 (a) Without doing an
stepladder [879]

Answer:

Step-by-step explanation:

Given are 3 data sets with values as:

(i) 8 9 10 11 12   ... Mean =10

(ii) 7 9 10 11 13    ... Mean =10

(iii) 7 8 10 12 13   ... Mean =10

We see that  data set shows mean deviations as

(i) -2 -1 0 1 2  

(ii) -3 -1 0 1 3    

(iii) -3 -2 0 2 3  

Since variance is the square of std deviation, we find that std deviation is larger when variance is larger.

Variance is the sum of squares of (x-mean).  Whenever x-mean increases variance increases and also std deviation.

Hence we find that without calculations also (i) has least std dev followed by (ii) and then (iii)

(i) (ii) (iii) is the order.

b) Between (i) and (ii) we find that 3 entries are the same and 2 entries differ thus increasing square by 9-4 twice.  But between (ii) and (iii) we find that

increase in square value would be 4-1 twice. Obviously the latter is less.

How many sides does a regular (equal sides and equal angles) polygon have if each exterior angle measures 24°? # of sides =?
lubasha [3.4K]
If the measure of each exterior angle is 24, the measure of each interior angle is then 180-24=156
the sum of the interior angles of a polygon is (n-2)*180, n is the number of sides
(n-2)*180=156*n
180n-360=156n
24n=360
n=15
the polygon has 15 sides
