A rational number is any number that can be written <em>as a ratio of two integers</em>.
0.62 fits the bill, as it can be written as the ratio 62/100 (or simplified to the ratio 31/50)
Answer: 19 1/2
Step-by-step explanation:
Hello!
We can write an expression to show this scenario. Write this in the equation format y = mx + b:
m = rate of change, or cost per ride
b = initial cost, or cost to enter the fair
y = 2.50x + 4
Solve for the amount of rides possible with $21.50:
21.50 = 2.50x + 4
Subtract 4 from both sides to isolate x:
17.50 = 2.50x
Divide both sides by 2.50:
17.50/2.50 = 7 rides.
Suppose that a=42, b=35, c is unknown, and C = 120°
