What is the value of x?<br><br> What is the value of y?
Rudik [331]

Answer:

Y= 20

X= 25

Step-by-step explanation:

The angles of a triangle have to equal 180

So

80+60 = 140

180 - 140 = 40

40/2 = 20

Y = 20

The angles of a linear line split equal 180

So

2y is one side of it which we learned Y = 20 which makes that side 40

To find the other side just guess and check

6(25) = 150

150 - 10 = 140

So the 2y = 40 and the (6x-10) = 140

So yea boom done

Please help me on this ​
Sveta_85 [38]

Answer:

14.125

Step-by-step explanation:

You combine the two equations and get

8x - 23

and since they're in a 90 degree angle you do

8x - 23 = 90

 add 23 to both sides

8x =113

divide 113 by 8 and you get 14.125 and if you plug it in for both x's you get 24.625 + 65.375 you get an even 90

Use the substitution method to solve the system of equations. Please help me get this question right
vaieri [72.5K]

Answer:  B (2,1)

You know what y is (x-1) so you substitute that for y in the other equation.

3x+ ((4)(x-1))=10

3x+4x-4=10

7x=14

x=2

Then put x=2 into y=x-1

y=2-1

y=1
