Answer:
100
Step-by-step explanation:
/_ ABC = /_ ABD + /_ DBC
Given: /_ABC = 130 and /_DBC = 30
* plug in known values *
130 = /_ ABD + 30
Subtract both sides by 30
130 - 30 = 100
30 - 30 cancels out
We're left with /_ABD = 100

Since it is 1 out of 14, take 400 and divide it by 14 (400/14) which would give 28.57142857... . So round to the nearest whole number = 29. SO THE ANSWER IS “C, 29”
Answer:
y = (-4/3)x
x = (3/4)y
Step-by-step explanation:
5.5x - 1.5y = 3.5x
<h2>Solve for Y:</h2>
5.5x + 1.5y = 3.5x ⇒ Subtract 5.5x from both sides
5.5x + 1.5y - 5.5x = 3.5x - 5.5x
1.5y = -2x ⇒ Divide Both sides by 1.5
1.5y ÷ 1.5 = -2x ÷ 1.5
y = (-2/1.5)x
y = (-4/3)x
<h2>Solve for X:</h2>
5.5x - 1.5y = 3.5x ⇒ Add 1.5y to both sides
5.5x - 1.5y + 1.5y = 3.5x + 1.5y
5.5x = 3.5x + 1.5y ⇒ Subtract 3.5x from both sides
5.5x - 3.5x = 3.5x + 1.5y - 3.5x
2x = 1.5y ⇒ Divide both sides by 2
2x ÷ 2 = 1.5y ÷ 2
x = (1.5/2)y
x = (3/4)y
