I think you do multiplying fractions. So 1 1/2 x 20
Since the deepest point of Death Valley is below sea level, its altitude is negative. So, the difference between the altitudes is

Subtracting a negative means to add, so we have

Answer:
y ∝ m and 1760 is a constant of proportionality.
Step-by-step explanation:
The relation between a distance in the yards (y) and the same distance in miles (m) is described by the equation y = 1760m.
So, the graph of the above equation passes through the origin(0,0) and it will be a straight line with a constant slope of 1760.
Therefore, a measurement in yards and a measurement in miles are in the relation of proportionality for the same distance.
Hence, y ∝ m and 1760 is a constant of proportionality. (Answer)
Answer:
81 hours
Step-by-step explanation:
He gets 10.5 dollars an hour over time and when he's working regular he earns 840 dollars so 840 divided by 10.5 is 80 so add an extra hour and he then makes more.
