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.

Answer:
25/416
Step-by-step explanation:
Maybe you want to know the value of ...
(1 1/4)/(20 4/5) = (5/4)/(104/5) = (5/4)×(5/104) = (5×5)/(4×104) = 25/416
The y-intercept of the graph of the equation is -18
<h3>What is an intercept?</h3>
An intercept is a point where the tangent to a curve or a straight line touches the x-axis or the y-axis.
Analysis:
y = 6(x-1)(x + 3)
y = 6( + 3x -x -3)
y = 6( +2x -3)
y = 6 +12x -18
The y-intercept of the equation occurs at x = 0
Therefore y = -18.
In conclusion, the y-intercept is -18.
