Move variable to the left. -w= -10+ 4W
-w-4W =-10
Collect like terms
-5w=-10 divide both sides by 5
Answer:
633-23=613-3
Just solve for each side then find what makes them equal.
Answer:
Step-by-step explanation:
Intersecting lines make equal opposite angles
2x + y = 50 - y
2x = 50 - 2y
x = 25 - y
A straight line represents 180°
4x + 6y + 2x + y + 2x + 3y = 180
8x + 10y = 180
8(25 - y) + 10y = 180
200 - 8y + 10y = 180
2y = -20
y = -10
x = 25 - (-10)
x = 35
Answer:
39
Step-by-step explanation:
The chords are equal to eachother. First multiply their divided lengths together:
9(3x-9)=21(x+1)
27x-81=21x+21
x=17
CD= 21+x+1
21+17+1=39
CD= 39
