The sequence follows a pattern of adding 3 to each number. Starting with 3, adding 3 gives us 6, adding 3 again gives us 9, and adding 3 one more time gives us 12. Therefore, the next number in the sequence is 12.

The correct answer is 7 because when we subtract 5 from both sides of the equation, we get x = 7.

The given expression is -4 multiplied by 12. When we multiply a negative number and a positive number, the result is always negative. Therefore, -4 multiplied by 12 equals -48.

The Battle of Fort Sumter marked the first exchange of fire in the Civil War. After the secession of several southern states, South Carolina demanded that Federal troops abandon Fort Moultrie. Union Major General Richard Anderson moved his troops to Fort Sumter, which he believed was more defensible. South Carolina seized all other Federal forts except for Fort Sumter. President James Buchanan authorized reinforcements to be sent to the fort, but they were fired upon and did not arrive. Confederate forces strengthened their position around Fort Sumter, and after General Anderson refused to surrender, Confederate forces began bombarding the fort. The battle had no casualties, but it galvanized both the North and the South in their war efforts.

The correction that should be made to sentence 4 is to change "don't" to "doesn't". This is because the subject of the sentence is "air", which is singular and requires the singular form of the verb "doesn't".

To convert a decimal to a fraction, we need to determine the place value of the decimal. In this case, the decimal .875 has three digits after the decimal point, which means it is in the thousandths place. To convert it to a fraction, we can write it as 875/1000. To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 125. Dividing 875 by 125 gives us 7, and dividing 1000 by 125 gives us 8. Therefore, the fraction equivalent of .875 is 7/8.

Confederate forces fired upon the ships carrying reinforcements to Fort Sumter, preventing them from reaching the fort. This was part of the Confederate strategy to isolate and weaken the Union forces at the fort, as they wanted to force its surrender. The firing upon the reinforcements was a significant event that escalated tensions and ultimately led to the start of the Civil War.

To convert years to days, we multiply the number of years by 365 (assuming a non-leap year). In this case, 2.5 years would be equal to 2.5 * 365 = 912.5 days. Since we need to round to the nearest full day, the answer would be 913 days.

The correction that should be made to sentence 10 is to replace "we" with "they". This is because the sentence is referring to new microwave owners, not the speaker or the writer. Therefore, the pronoun "they" should be used to indicate the owners, not "we".

To find 20% of 200, we can multiply 200 by 0.20. This gives us 40. Therefore, the correct answer is 40.

The correction that should be made to sentence 11 is to change "Recipes" to "recipes".

The equation is evaluated using the order of operations, which states that multiplication and division should be done before addition and subtraction. First, we calculate 3 x 5, which equals 15. Then, we calculate (3+2) x 2, which equals 10. Next, we subtract 15 from 25, resulting in 10. Finally, we add 10 to 10, giving us the final answer of 20.

The answer "Snakes are best distinguished by their coloration, their scales, and the presence of a pit" best summarizes the information on the key because the person's observations of the snake's coloration and smooth, cycloid scales are mentioned. Additionally, the absence of other markings suggests that coloration and scales are important for identifying snakes. The presence of a pit is also mentioned as a distinguishing characteristic, further supporting the idea that coloration, scales, and the presence of a pit are key factors in snake identification.

Major General Anderson moved his troops to Fort Sumter because he believed that Fort Moultrie was harder to defend than Fort Sumter.

This is evident in the fact that the man does not fully comprehend the extreme danger and potential consequences of the freezing temperatures and harsh conditions he is facing. He only sees the cold as uncomfortable and something to be protected against, without considering the fragility of human life and the broader implications of his situation. Therefore, the narrator is suggesting that the man cannot see the danger he was in.

The best way to write the underlined portion of the sentence is "have microwave ovens and must learn." This is the correct answer because it maintains parallel structure by using the conjunction "and" to connect the two verbs "have" and "must learn."
