Answer:
x = -0.8y
Step-by-step explanation:
Simplifying
4y + 5x = 0
Reorder the terms:
5x + 4y = 0
Solving
5x + 4y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4y' to each side of the equation.
5x + 4y + -4y = 0 + -4y
Combine like terms: 4y + -4y = 0
5x + 0 = 0 + -4y
5x = 0 + -4y
Remove the zero:
5x = -4y
Divide each side by '5'.
x = -0.8y
Simplifying
x = -0.8y

Step-by-step explanation:
Answer:
In 1.25 hours, their combined speed is 40 km, so their speed per hour is 32 km/h
So the answer is B. northbound bicyclist = 18 km/h
southbound bicyclist = 14 km/h
Step-by-step explanation:
the speed of the slower is x and the faster x+4 km/h
that equals 32 km and the speed of the slower is 14 km/hr and the faster 18 km/hr.
in 1h15m the slower goes 17.5 km and the faster 22.5 km
Divide the numbers but 70 has 2 numbers so take the decimal point and move it 2 spaces over and then divide
$430 because you divide 15,480 divided by 36 and get your answer
