Answer:
a
Step-by-step explanation:
Given
y - 3 = (x + 6)
Multiply through by 2 to clear the fraction
2y - 6 = x + 6 ( subtract 2y from both sides )
- 6 = x - 2y + 6 ( subtract 6 from both sides )
- 12 = x - 2y, that is
x - 2y = - 12 → a
That would be 222,111 answer
Answer:
x = 200
Step-by-step explanation:
1/5x – 2/3y = 30
substitute in y
1/5x - 2/3(15) = 30
multiply
1/5x - 10 = 30
isolate the variable
1/5x = 40
multiply each side by 5
x = 200
Answer:
40 degrees
Step-by-step explanation:
- All internal angles of a triangle add up to 180 degrees.
- A right angle is 90 degrees.
90+50=140
subtract 140 from 180, which is 40 degrees.
