Answer:
3.
Step-by-step explanation:
The scale factor is basically what figure B is divided by.
9 / 3 = 3
3.6 / 3 = 1.2
We need two equations for this.
A) (H * J) / (H + J) = 3
Harry is 8 hours faster than Jimmy
B) H + 8 = J
Inserting equation B into A gives us:
A) (H * (H+8))/ (H + H +8) = 3
H^2 +8H / (2H +8) = 3
H^2 + 8H = 6H + 24
H^2 + 2H -24 = 0
H = 4
and so J = 12
Harry takes 4 hours and Jimmy takes 12 hours.
Answer:
0, 5, 7
Step-by-step explanation:
You just follow the rule written at the top, if the left column is x, the right column is x/6. For example, if the right column is 0, the left would be 0/6, which is 0.
