Solve for x: -2(x + 3) = -2x - 6
0
3
O All real numbers
O No solution
Answer:
All real numbers
Explanation:
Step 1: Apply distributive property.
[tex](-2)(x) + (-2)(3) = -2x -6[/tex] [tex]-2x - 6 = -2x - 6[/tex]Step 2: Add 2x to both sides.
[tex]-2x - 6 + 2x = -2x - 6 + 2x[/tex] [tex]-6 = -6[/tex]Step 3: Add 6 to both sides.
[tex]-6 + 6 = -6 + 6[/tex] [tex]0 = 0[/tex]Therefore, the answer is all real numbers.

The three parts, identical in size, are each made of a different ceramic compound. The parts are heated to the same temperature and placed under the same stress loads. At the end of the test, the engineer concludes Part B is the best for the job. What was the independent variable in this test?
Select one:
a. dimensions of the parts
b. temperatures to which the parts were heated
c. the engine used to test the parts
d. the composition of the parts

What is the number of chromosomes in each Meiosis I daughter cell
Answer:23 chromosomes
Explanation:
To take human being for example,
There is 46 chromosomes in a human cell, and half is from father, and the other half is from mother. We call the chromosome is a pair. We write it 2n= 46.
In the meiosis I, the chromosomes is 1n=23.

Calculate the total resistance (in Ohms) of a light bulb marked 2V and 3A. Do not add units. Leave your answer as a decimal to 2 decimal places.
The total resistance of a light bulb marked 2V and 3A is 0.67ohms
HOW TO CALCULATE RESISTANCE:
The resistance of a substance can be calculated by using the formula as follows:R = V/I
Where;
R = resistance (in ohms)V = voltage (in volts)I = current (in amperes)According to this question, a light bulb is marked 2V and 3A. The resistance (R) can be calculated as follows:R = 2V ÷ 3A
R = 0.67ohms.
Therefore, the total resistance of a light bulb marked 2V and 3A is 0.67ohms.Learn more at: https://brainly.com/question/8776047?referrer=searchResults

A day on Earth is approximately 24 hours, which is the amount of time it takes for Earth to complete one
rotation around its axis. How do the two tidal bulges created by the Moon align with the number and
frequency of tides for each coastal city??
Answer:
Because the Earth rotates through two tidal “bulges” every lunar day, coastal areas experience two high and two low tides every 24 hours and 50 minutes. High tides occur 12 hours and 25 minutes apart. ... This occurs because the moon revolves around the Earth in the same direction that the Earth is rotating on its axis.
The two bulges created by the Moon align with the number and frequency of tides for each coastal city by the fact that the coastal cities experienced two consecutive high and low tides within the time interval of 24 hours and 50 minutes.
What do you mean by Tidal bulges?Tidal bulges may be defined as a type of natural phenomenon that significantly involves the gravitational attraction between the moon and the Earth provoking the water in the oceans which is present in a fluid state and mobile in nature.
These attributes force the water to be pulled toward the moon and stimulate the production of bulges. And due to the revolution of the earth on its axis changes the location of the water.
The process of tidal bulges accomplished the consistent revolution of the moon around the earth with respect to the rotation of the earth on its axis in the same direction.
Therefore, the coastal cities experienced two consecutive high and low tides within the time interval of 24 hours and 50 minutes.

Does hot water tend to rise or sink? Explain.
Answer:
When fluids (liquids and gases) are heated, they expand and therefore become less dense. Any object or substance that is less dense than a fluid will float in that fluid, so hot water rises (floats) in colder water.
Explanation:
When you heat up water, the water molecules start moving around faster and faster. ... So hot water is less dense than cold water. When you put the two together with the hot water on the bottom, the hot water rises to the top.

what is a major difference between messenger rna molecules and transfer rna molecules?
Answer:
1) Messenger RNA molecules contain ribose, and transfer RNA molecules contain deoxyribose.
2) Messenger RNA molecules function in carrying coded information to the ribosomes, and transfer RNA molecules function in carrying amino acids to the ribosomes.
The major difference between messenger RNA molecules and transfer RNA molecules is that messenger RNA carries the genetic information, while tRNA carries the amino acids.
What is RNA?RNA is ribonucleic acid. In the cell, different types of RNA are found, such as mRNA (messenger RNA), tRNA (transfer RNA), rRNA (ribosome RNA), SnRNA, miRNA, etc. mRNA, or messenger RNA, is formed from DNA. It carries the information of a cell. The three consecutive nucleotides of mRNA make up a codon. An example of a codon is AUG.
tRNA has a cloverleaf-like structure. It has different domains such as the TΨC loop, the DHU loop, the anticodon region, and at the 3' end it is attached to an amino acid. The anticodon of the tRNA reads the codon sequence of the mRNA and attaches the amino acids. For the AUG codon methionine is attached.
Hence, the main difference between the messenger RNA and transfer RNA molecules is that mRNA carries the message of the genetic material, while tRNA carries amino acids to express the genetic material on mRNA.
