2x - 27=56
the answer to the question
Answer:
x > - 3
Step-by-step explanation:
Given
3(x + 2) > x ← distribute left side
3x + 6 > x ( subtract x from both sides )
2x + 6 > 0 ( subtract 6 from both sides )
2x > - 6 ( divide both sides by 2 )
x > - 3

Answer:
Step-by-step explanation:
The proportion that Alan solved was
x/200 = 8/25
His working as shown was
(8)(x) = (25) (200)
8x = 5000
He divided both sides of the equation by 8. It became
8x/8 = 5000/8
x = 625
The correct steps are
25x = 200 × 8 = 1600
Dividing both sides of the equation by 25, it becomes
x = 1600/25
x = 64
Alan's error were:
1) He got the wrong product when he multiplied 25 by 200.
2)He got the wrong quotient when he divided 5,000 by 8.
