<u>Answer:</u>

  • x = -3

<u>Step-by-step explanation:</u>

  • \frac{12 + 6x}{3} = \frac{5 - 9}{2}
  • => 2(12 + 6x) = 3(5 - 9)
  • => 24 + 12x = 15 - 27
  • => 24 + 12x = -12
  • => 24 + 12 = -12x
  • => 36 = -12x
  • => x = -3

<u>Conclusion: </u>

Therefore, x = -3

Hoped this helped.

Answer: I hope this helps! :)

x = -3

  1. rearrange terms: 6x+12/3 = 5-9/2
  2. subtract the numbers: 6x+12/3 = -4/2
  3. eliinate fractions denominators: 3 times 6x+12/3 = 3(-2)
  4. simplify fractions: 6x+12/3 = -2
  5. eliinate fractions denominators: 3 times 6x+12/3 = 3(-2)
  6. multiplt the numbers: 6x + 12 = -6
  7. subtract 12 from both sides of the equation: 6x + 12-12 = -6-12
  8. simplify: 6x = -18
  9. divide both sides of the equation by the same factor: 6x/6 = -18/6
  10. x = -3

Answer: x=-3

A target with a diameter of 14cm has 4 scoring zones by concentric circles. The diameter of the center circle is 2 cm. The width
Leni [432]

Answer:

48.98\%

Step-by-step explanation:

we know that

The probability that it will hit a point in the outer (yellow) ring is equal to divide the area of the yellow ring by the total area of the target

step 1

Find the area of the yellow ring

A=\pi [7^{2} -5^{2}]

A=24\pi\ cm^{2}

step 2

Find the total area of the target

A=\pi [7^{2}]

A=49\pi\ cm^{2}

step 3

Find the probability

24\pi/49\pi=0.4898

Convert to percentage

0.4898*100=48.98\%

John put away 36 of 48 shirts in his closet. Don has 84 shirts. If he put away the same percent, how many shirts did Don put in
Alexeev081 [22]

Answer:

63

Step-by-step explanation:

John's percentage:

36 and 48 have a common factor of 12 so divide both of them by 12.

36/12= 3 and 48/12=4 therefore

so 36/48= 3/4 which is 75% but we don't need to focus on the percent.

Don's no. of shirts:

we know Don has 84 shirts so we say

3/4 of 84= no. of shirts that Don put in his closet

84/4=21 21x3=63

Don put 63 shirts in his closet.

Hope that helped! Anymore questions just ask! :)

What is the value of x? There is isosceles triangle. The measure of angle which is between two congruent sides is (6x+10⁰). The
max2010maxim [7]
<h3><u>Answer</u><u>:</u><u>-</u></h3>

x=17

<h3><u>step-by</u><u>-</u><u>step</u><u> </u><u>Explanation</u><u>:</u><u>-</u></h3>

{\boxed{\quad\:\mapsto\rm Firstly\:Let's\:understand\:the\:concept:-}}

<h3 />

This is a isosceles triangle. As it is a triangle we can apply sum theory. we have to take the sum of given unknown polynomials as 180° .Then by solving it we can find the value of x.

<h3><u>Solution</u><u>:</u><u>-</u></h3>

Given angles

  • (6x+10°)
  • (x+17°)
  • (4x-34)°

According to sum theory

{\boxed{\sf The \:sum\:of\:angles=180°}}

  • Substitute the values

\qquad \quad{:}\longmapsto\tt (6x+10)+(x+17)+(4x-34)=180

  • Remove brackets

\qquad \quad{:}\longmapsto\tt 6x+10+x+17+4x-34=180

  • Together like polynomials and constants

\qquad \quad{:}\longmapsto\tt 6x+x+4x+10+17-34=180

\qquad \quad{:}\longmapsto\tt 11x-7=180

  • Interchange sides

\qquad \quad{:}\longmapsto\tt 11x=180+7

\qquad \quad{:}\longmapsto\tt 11x=187

\qquad \quad{:}\longmapsto\tt x=\cancel{\dfrac{187}{11}}

  • Simplify

\qquad \quad{:}\longmapsto\tt x=17

\therefore\sf The \:value\:of\:x\;is\:17.
