Answer:
Step-by-step explanation:
they are opposite angles, so we put them equal to each other.
25.
6a+10= 130
6a=120 a=20 so now we plug it in 6(20) +10= 130
26. 4a-4=2a+30
2a=34 a=17 sso now we plug in 4(17)-4= 64 2(17)+30= 64
27. 6y+1=4y+9 2x-5=x+7
2y=8 x=2
y=4
now plug in 6(4)+1=25 4(4)+9=25 2(2)-5= -1 (2)+7=9
Answer:
what happened to spinner b
Step-by-step explanation:
To write a linear equation in standard form, move each variable term to the left side of the equation and simplify. Ax +By = C
Since x is on the right side of the equation, switch the sides so it is on the left side of the equation. 3/4 * (x+8) = y-4
Move all terms containing variables to the left side of the equation
3x/4 +6 = y-4
Move the y to the left side of the equation
3x/4+6-y=-4
Move all terms not containing a varbile to the right side
Move the 6 to the right side
3x/4-y=-6-4
Subtract 4 from -6
3x/4-y=-10
Find the LCD of A,B,C and you get 4
Then you * 4 by everything
3x/4*4-y*4=-10*4
Simplify each term
3x-4y=-10*4
Multiply -10 by 4
3x-4y=-40
