In the graph, the constant of proportionality is 40
<h3>Calculating the constant of proportionality</h3>
From the question, we are to determine the constant of proportionality
The constant of proportionality =
From the graph, a point on the line is (1, 40)
That is,
When x = 1 and y = 40
Thus,
The constant of proportionality =
Constant of proportionality = 40
Hence, the constant of proportionality is 40

If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.
Is this the whole question?
Answer:
11:10
Step-by-step explanation:
1h15m + 40m + 25m + 30m = 2h50m
She'd need to start 2h50m before 2:00, which would be 11:10 I think
You put those equal to each other that find the x and than x value to x+3.
