To find the constant of proportionality<span> here let's look at the </span>equation<span> of a line for a straight graph that passes through the origin. y is your vertical y-value for any given point on the line, x is your horizontal x-value for any given point on the line, and m is the slope.</span>
Answer:
58
Step-by-step explanation:
95 - 55 = 45
2600 / 45 = 57.77778.....
Because you can't sell 0.777778 of a bike you instead sell 58
From the information we have, Jack drove 401/2 miles and used a total of 1 1/4 gallons of gasoline.
We need to find out how many miles he travelled per each gallon.
40 1/2 miles can be written as 40.5 miles
1 1/4 gallons can be written as 1.25 gallons.
So now we form an equation.
40.5 = 1.25
x = 1
Where x is the number of miles per gallon
We cross multiply the equation
40.5 * 1 = 1.25 * x
40.5 = 1.25x
40.5 / 1.25 = x
32.4 = x
x = 32 .4
So the unit rate for miles per gallons is 32.4 miles per gallon
Answer: 71.6°
