i wish i could help
Explanation:
iwe have that
x + (2x + 40) + (3x – 50) = 15,002
Reorder the terms:
(x+2x+3x)+(40-50)=15,002
Combine like terms:
x+2x+3x=6x
40-50=-10
6x-10=15,002
adds +10 both sides
6x-10+10=15,002+10
Combine like terms:
-10+10=0
15,002+10=15,012
6x=15,012
we have that
x + (2x + 40) + (3x – 50) = 15,002
Reorder the terms:
(x+2x+3x)+(40-50)=15,002
Combine like terms:
x+2x+3x=6x
40-50=-10
6x-10=15,002
adds +10 both sides
6x-10+10=15,002+10
Combine like terms:
-10+10=0
15,002+10=15,012
6x=15,012
we have that
x + (2x + 40) + (3x – 50) = 15,002

Explanation:
what was the problem with reusing contaminated water from other parts of the mill to extinguish the coke fires? From the book ‘When smoke ran like water’
Answer:
1. The problem with that was that the already poisonous water was made worse after using it to quench the flames from coke production.
2. It contaminated the soil, making it difficult for plants to grow.
Explanation:
As the author described the last stages of coke production, she explained that water was needed to quench the very hot flames from coke production. A 'bright fellow' suggested using dirty water from other parts of the mill to quench the flames from the coke production. The problems with this were;
1. The already contaminated water was made worse after it was used to quench the flames from coke.
2. Mrs. LaMendola noted that she was unable to grow her tomatoes in the path where the plumes from the oven ran. So the contaminated water negatively affected the soil.
The problem that should be already poisonous water is also made worse when it quenches the flames at the time when the production of the coke should be done.
Also, it contaminated the soil also it is difficult for growing the plants.
The problem of reusing contaminated water:Since the author explained the last coke production stage so here the water required to quench that it should be very hot flames arise from the coke production. Also, the contaminated water should be worse whenever it is used for quenching the flames. Also, the contaminated water does not positively impact the soil.

Paragraph about Photosynthesis
Answer:
Photosynthesis is the process of making food by green plants in the presence of sunlight.
Explanation:
During Day, sunlight enters through stomata and carbon dioxide from air and water forms glucose and oxygen. This process is photosynthesis.
what are the inputs and outputs of the reaction
Answer:
The inputs are carbon dioxide from the air and the ATP and NADPH produced by the light reactions. The cycle's output is an energy-rich sugar molecule. The Calvin cycle uses carbon from the carbon dioxide, energy from the ATP, and high-energy electrons and hydrogen ions from the NADPH.
Explanation:
The light reactions, which occur during photosynthesis, have specific inputs and outputs. The inputs of the light reactions include light energy and water. The outputs of the light reactions are ATP (adenosine triphosphate), NADPH (nicotinamide adenine dinucleotide phosphate), and molecular oxygen.
Light energy is absorbed by the chlorophyll pigments in the thylakoid membranes, while water molecules serve as a source of electrons for the photosynthetic electron transport chain.
ATP is a high-energy molecule that serves as the primary energy source for cellular processes. NADPH is a coenzyme that carries energized electrons and plays a role in the synthesis of carbohydrates during the subsequent dark reactions of photosynthesis. Molecular oxygen is a byproduct of light reactions and is released into the atmosphere as a waste product. Together, these outputs provide the energy and reduce the power needed for the synthesis of organic molecules during photosynthesis.
Therefore, the inputs of the light reactions include light energy and water. The outputs of the light reactions are ATP (adenosine triphosphate), NADPH (nicotinamide adenine dinucleotide phosphate), and molecular oxygen.

atoms
Answer: All substances are built from
compound
oxygen
Explanation:
All substances are built from atoms as atoms are the basic building blocks of matter and are the smallest units of a chemical element. The correct option is D.
Atoms form the basis of all compounds. The fundamental building blocks of matter, atoms are the smallest units of a chemical element that nonetheless retain that element's chemical characteristics.
Atoms from various elements combine chemically to produce compounds, however compounds themselves are not the basic building blocks.
Although oxygen is an element that is present in several substances, it is untrue to say that oxygen is the primary component of all substances.
Although metals are a specific kind of element, not all substances are made of metals. Thus, the most correct response is that all substances are composed of atoms.
Thus, the correct option is D.

what is the meaning of half life ?A radioactive element is defined as the material when it changes its atomic number or weight by emitting energy, the energy may be either Alpha, beta, or gamma forms of radiation.
Alpha is a Helium nucleus, a beta particle is an electron and a gamma is high energy electromagnetic radiation. Half-Life can be defined as the time required by which the radioactive substance to split into a different substance.
The half life was first discovered by Ernest Rutherford and represented by the Ug or t1/2, If the radioactive element has one-hour of half-life, it means one half of the element would decay within an hour and the remaining part would decay in another hour.

Write a summary statement for saturated fats including whether they are solids or liquids at room temperature and weather they have all single carbon-to-carbon or at least one carbon-to-carbon bond
Answer:
A saturated fat is a type of fat in which the fatty acid chains have all or predominantly single bonds. A fat is made of two kinds of smaller molecules: glycerol and fatty acids. Fats are made of long chains of carbon atoms. Some carbon atoms are linked by single bonds and others are linked by double bonds. Double bonds can react with hydrogen to form single bonds. They are called saturated because the second bond is broken and each half of the bond is attached to a hydrogen atom.
Explanation:
Answer:
saturated fats consists of single covalent bond and they are solid at room temperature and their melting point increases with increasing chain length

NEED HELP ASAP!!!! Explain why the fact that invasive species did not co-evolve with the native species unbalances an ecosystem.
Answer: The invasive species unbalance an ecosystem because it takes over an ecosystem and does not let the other native species thrive while it takes over. There are many invasive species around the world even in your own town or state there is a type of fish suppose that is an invasive species to Michigan called a sea lamprey which kills fish native to the great lakes and is taking over there are also zebra muscles if you need another example
BRAINLIEST PLZ
Invasive species lack native species' population controls, such as predators, because they did not co-evolve with the other species in the ecosystem. As a result, the population of an invasive species may spread unchecked and eventually throw an ecosystem out of balance.
Unbalances in ecosystem :
A natural or human-caused disruption that throws off an ecosystem's natural balance is known as an ecological imbalance. Both natural and man-made disturbances have the potential to upset an ecosystem's delicate balance. A species' extinction or the introduction of a new species may cause an ecosystem to become ecologically unbalanced.
All the organisms and the physical setting they interact with make up an ecosystem. The nutrition cycles and energy flows connect these biotic and abiotic elements. Photosynthesis is how energy enters the system and is absorbed by plant tissue. Both internal and external influences influence ecosystems. External variables that do not directly affect an ecosystem, such as topography, parent material that creates the soil, and climate, control the ecosystem's general structure. For instance, decomposition, root competition, shade, disturbance, succession, and the kinds of species present all regulate internal variables. While the availability of these resources within the ecosystem is normally governed by internal factors, the resource inputs are often controlled by external activities. As a result, interior variables influence ecological processes as well as being influenced by them.
