Answer:
46.5 miles
Step-by-step explanation:
Average speed × Time in hours = Distance
Average speed = 15.5 Miles per hour
Time = 180 minutes
We convert to hours
60 minutes = 1 hour
180 minutes = x
Cross Multiply
60x = 180
x = 180/60
x = 3 hours
Distance = 15.5 miles per hour × 3 hours
Distance = 46.5 miles
The distance Rico will ride his bicycle is 46.5 miles

Answer:
The solution to the system of equations is y = -5 and x = -2.
Step-by-step explanation:
The question tells us to use substitution to solve the system. This means that the given value for x (in terms of y) should be substituted into the other equation. This is modeled below:
-4y - 5x = 30
-4y - 5(y+3) = 30
Next, we should use the distributive property to simplify the left side of the equation.
-4y -5y - 15 = 30
The next step is to combine like terms on the left side of the equation.
-9y - 15 = 30
Then, we can add 15 to both sides of the equation.
-9y = 45
Finally, we can divide both sides of the equation by -9.
y = -5
To find the value for x, we substitute in the value we just found for y into either of our original equations.
x = y + 3
x = -5 + 3
x = -2
Therefore, the correct answer is y = -5 and x = -2.
Hope this helps!
