Answer:

B. -1

Step-by-step explanation:

-6 = -9 - 3x

1. get the variable <em>x</em> by itself by adding 9 to both sides

-6 = -9 - 3x

+9 +9

3 = -3x

2. solve for <em>x </em>by dividing by -3 on both sides

3 = -3x

/-3 /-3

3/ -3 = -1

x = -1

Answer:

1) x=30 degrees

2)y=20 degrees

1) 3x+2x+1x= 6x (a triangle is normally 180 degrees) 180 divide 6=30 (this is because 6 Xs make up the triangle)

2) 2y+5y+5+y+15= 8y+20, (since a triangle has 180 degrees) 8y+20=180 (-20 from both sides) 8y=160, 160 divide 8=20

(I hope this makes sense)
