Answer:
27
Step-by-step explanation:
The sum of all exterior angles of any quadrilateral= 360°
3x+2x+40+x+50+4x = 360°
11x + 90 = 360°
11x = 360 - 90
10x = 270
x = 270/10
x = 27

Answers
Answer:
1:4 ratio
Step-by-step explanation:
The Answer is a 1:4 ratio because 1/5 of 10 is 2 and 4/5 of 10 is 8 so the ratio would look like 2:8. You would then simplify 2:8 to 1:4.
Ratio of red to blue marbles is 1:5
An equation is used to show the relationship between two or more numbers and variables.
10 marbles in a bag 1/5 are red and the others are blue.
number of red marbles = 1/5 * 10 = 2
number of blue marbles = 10 - 2 = 8

[tex] \sqrt{x + 9} = x - 3[/tex]
Sides gets power 2
[tex] ({ \sqrt{x + 9} })^{2} = ( {x - 3})^{2} [/tex]
[tex] |x + 9| = {x}^{2} - 6x + 9 [/tex]
_________________________________
[tex]x + 9 = {x}^{2} - 6x + 9[/tex]
Subtract sides 9
[tex]x + 9 - 9 = {x}^{2} - 6x + 9 - 9[/tex]
[tex]x = {x}^{2} - 6x[/tex]
Subtract sides x
[tex]x - x = {x}^{2} - 6x - x[/tex]
[tex] {x}^{2} - 7x = 0[/tex]
[tex]x(x - 7) = 0[/tex]
[tex]x = 0[/tex]

[tex] x = 7[/tex]
_________________________________

Subtract sides 9

[tex]x = - {x}^{2} + 6x - 18 [/tex]
Subtract sides x
[tex]x - x = - {x}^{2} + 6x - 18 - x [/tex]

[tex] \sqrt{0 + 9} ≠0 - 3[/tex]
[tex] \sqrt{9} ≠ - 3[/tex]

Thus (( x = 0 )) is unacceptable.

x - 2y = 0 solve using substitution please show work
Answers
Answer:
(6,3)
Step-by-step explanation:
I'm going to start with the second one.
x - 2y = 0
+2y +2y
x = 0 + 2y which is the same as (x = 2y)
Now plug that in for the x-value in the other equation.
4(2y) - 3y = 15
8y - 3y = 15
5y = 15
Divide both sides by 5
y = 3
Here is where you are going to plug it back into the first one we did.
x - 2(3) = 0
x - 6 = 0
+6 +6
x = 6
So the answer is (6,3)
Hope that helps and have a great day!
