Answer:
First ?: 4
Second ?: -6
Step-by-step explanation:
40-40=0, which leaves 4n left.
34-40=-6
The final answer would be n= 3/2.
The scale factor of the dilation is 0.5
<h3>How to determine the scale of dilation?</h3>
From the figure, we have the following lengths:
AB = 2
AB' = 1
The scale factor of dilation is then calculated as:
Scale factor = AB'/AB
This gives
Scale factor = 1/2
Evaluate
Scale factor = 0.5
Hence, the scale factor of the dilation is 0.5

Answer:
They are supplementary.
Step-by-step explanation:
If two angles form a linear pair, the angles are supplementary.
When 5 adults joined the group of y: y+5
The ratio of the number of adults to children became 3:5, so the number of children to total diner should be 5:8. (8=3+5)
So the number of children would be (5/8)*(y+5) = (5y+25)/8
