Answer:
Answer: The system of equations are
x + y = 10
3.75x + 2.5y = 35
Step-by-step explanation:
Let x represent the number of cupcakes that Camila bought.
Let y represent the number of brownies that Camila bought.
She bought a total of 10 cupcakes and brownies altogether. This would be expressed as
x + y = 10
Camila and her children went into a bakery and she bought $35 worth of cupcakes and brownies. Each cupcake costs $3.75 and each brownie costs $2.50. This would be expressed as 3.75×2.5y =35
Answer:
The correct answer is D.
Explanation:
Descriptive science investigation is a study model, according to which a phenomenon is approached and its elements are characterized and its conceptualized, according to a series of methods used for data collection and expression of the same, that is, through this type of research, which uses the method of analysis, it is possible to characterize an object of study or a specific complex system, point out its characteristics and properties. The main objective of this research is the relationship between the factors, the actors and the variables. Researchers not only collect data through observation but are in charge of studying and analyzing to obtain meaningful results that can contribute to knowledge.
Because carbon dioxide is a GREENHOUSE GAS, it can trap the sun's heat in the atmosphere. Because the factory is made of concrete, it may deplete groundwater levels overtime by not allowing water to INFILTRATE.
Greenhouse gases trap the sun's heat and this is how we can feel it. Without greenhouse gases the earth's average temperature would be 30 degrees less. Other greenhouse gases include water vapor and methane. Increases in the levels of Greenhouse gasses are responsible for present day global warming.
Infiltration is the process by which water enters the soil and eventually becomes part of the groundwater.
Xylem tissue is important is the transport of water and minerals from the roots to the leaves of the plant. It is this water that is used in photosynthesis and also significant in the transpirational pull that significant in plant support. When the xylem is destroyed the plant wilts because it loses turgidity and dies because water is unable to reach the leaves for photosynthesis so the plant cannot make its food.
