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.
3x3 -4= 5 5(-1)= -5 -5(-4)= 20
Answer:
f(-1) = 12
f(1) - g(1) = 8
g(x) = 4 when x = 2
f(x) = g(x) when x = 3
Step-by-step explanation:
Read the graph.
Find the x - values on the x - axis and identify what y level the line is at.
45x20x18=16,200
350x9=3150
total = 19,350
