B-ad=3c+r solve for c
DENIUS [597]

By making c the subject of formula in the given equation, the value "c" is equal to c = (B - ad - r)/3.

<h3>What is an equation?</h3>

An equation can be defined as a mathematical expression which shows that two (2) or more thing are equal.

In this exercise, you're required to solve for c from the given mathematical expression (equation) by making it the subject of formula. This ultimately implies that, all the other variables would be defined in terms of c and they would all be on the same side of the "equal to" symbol.

Making c the subject of formula, we have:

B - ad = 3c + r

3c = B - ad - r

Dividing both sides by 3, we have:

3c/3 = (B - ad - r)/3

c = (B - ad - r)/3.

What is the difference between quantative and qualitative analysis​
AlexFokin [52]

Answer:

Quantitative data can be counted, measured, and expressed using numbers.  Qualitative data is descriptive and conceptual.  Qualitative data can be categorized based on traits and characteristics.

Explanation:

Quantitative analysis involves looking at the hard data, the actual numbers. Qualitative analysis is less tangible. It concerns subjective characteristics and opinions – things that cannot be expressed as a number.

What variable did the researchers intentionally vary in the experiment, and what are the units for this variable? what variable
Aloiza [94]
Answer is: <span>time of reaction, in minutes (data in attachment).
</span>Glucose 6-phosphatase, which is found in mammalian liver cells, is a key enzyme in control of blood glucose levels. The enzyme catalyzes the breakdown of glucose 6-phosphate into glucose and inorganic phosphate.<span> These products are transported out of liver cells into the blood, increasing blood glucose levels. In this exercise, you will graph data from a time-course experiment that measured </span>concentration in the buffer outside isolated liver cells, thus indirectly measuring glucose 6-phosphatase activity inside the cells.

Which part of an atom is positively charged, and which part is negatively charged?.
charle [14.2K]

The electron is negatively charged, while the nucleus is positively charged.

Protons and electrons, two of the subatomic particles, each have an electrical charge of one or the other. On the other hand, neutrons lack a charge. Protons and neutrons make up the nucleus (or core) of an atom. Where an atom belongs on the Periodic Table is essentially determined by the number of protons in its nucleus, or "atomic number." The features of an atom are also largely determined by the number of protons in the nucleus.

Hence, electron is negative charge particle and proton is positive charge particle both present in equal proportion to neutral atom.
