Answer:

x = -7

Step-by-step explanation:

5x+8=3x-6

Subtract 3x from each side

5x-3x+8=3x-3x-6

2x+8 = -6

Subtract 8 from each side

2x+8-8 = -6-8

2x = -14

Divide by 2

2x/2 = -14/2

x = -7

Answer: x= -7

Step-by-step explanation:

$5x+8=3x-6$

$\mathrm{Subtract\:}8\mathrm{\:from\:both\:sides}$

$5x+8-8=3x-6-8$

$5x=3x-14$

$\mathrm{Subtract\:}3x\mathrm{\:from\:both\:sides}$

$5x-3x=3x-14-3x$

$2x=-14$

$\mathrm{Divide\:2\:\:on\:\:both\:sides\:}$

$-14/2=-7$

$x=-7$

Hey! since it’s a 5 sided shape it’s area will be 540° so you add up 108+100+90+120=418
the final angle is 122*
then since angles on a straight line is 180° you minus 122 from 180 and x= 58°

Answer:

z=20.8

x=16.97

y=12

Step-by-step explanation:

The triangle on the right is a 30,60,90 triangle, a special right triangle with simple rules to find the side lengths. sides A,B, and C where C is the hypotenuse (24 in your diagram). The short side A is= 1/2 of side C (12 in your diagram). The long side B is= side A*√3 (20.8 in your diagram).

The triangle on the left is another special right triangle called a 45,45,90. The rules for this triangle are C= A*√2, and B=A. Because of the rules in the 30,60,90 triangle, we know that side A is 12. This means that side B (y)=12. Side C (x)= 16.97.

Hope this helped! Sorry if my explanation is confusing, but the rules for special right triangles can be easily found online and then calculated :)

19.Find the median of the distribution 5,9,8,6,3,5,7,12 and 13 1 -

77julia77 [94]

Answer:

Your answer is 7

Step-by-step explanation:

First place the numbers in order from lest to greatest, then use your two index fingers to find the middle number from all the numbers, like this:

3, 5, 5, 6, 7, 8, 9, 12, 13

P.S. is the number "1" part of the numbers? Because if it is then you need to do the same thing of ordering the numbers and if there are two numbers in between, all you have to do is add & divide.

1, 3, 5, 5, 6, 7, 8, 9, 12, 13

6 + 7 = 13; 13/2 = 6.5

If that's the case, then your answer is 6.5.
