28 laps/hour
You divide 35 by 1.25, and you get 28.
Another way is to look at it as 5/4. So 35 divided by 5 gives you 7 laps per 1/4 hour. Then 7 times 4 gives you 28 laps per hour.
So one easy way is to make the equation equal to only one place holder so
-7x-4y=16
add 7x to both sdies
-4y=16+7x
multiply both sides by -1
4y=-16-7x
divide both sides by 4
y=-4-7/4x
subsitute values for x and get values for y
exg
if x=0 then y=-4
if x=1 then y=-5 3/7
etc

Answer:
Sewage treatment and nitrous oxide
Step-by-step explanation:
Sewage to treatment and nitrous oxide is correctly paired with the greenhouse gases that it increases.
Greenhouse gas refers to gases that has the property of absorbing infrared radiation (net heat energy) emitted from Earth’s surface and reradiating it back to Earth’s surface, thus contributing to the greenhouse effect.
Examples of greenhouse gases and the most important greenhouse gases are methane, carbon dioxide (CO2), and water vapor.
Human activities such as fossil-fuel combustion are responsible for increase in the atmospheric concentration of various greenhouse gases, especially carbon dioxide, methane and ozone.
