**Grammar**

we want the first sentence. You are correct. The reason is we need a comma after each list including the second to last one with the "and" word.

**Math**

We want the denominators to be equal to find which is greatest and which is the least. Thus, we find the lcm or the least common denominator of 2,6, and 8. This happens to 24. Thus, we multiply 3/8 by 3/3 to get 9/24, we multiply 5/6 by 4/4 to get 20/24, and we multiply 1/2 by...

**Grammar**

like before, we cross out the prepositional phrase to get the dean is/are in favor of the plan. we know the dean is singular, so we choose the verb of being for singular....

**Grammar**

Excuse me, but where is the sentence? But a correct sentence has no grammatical or punctuation errors. A run-on sentence has two sentences joined together without a conjunction (usually), and a sentence fragment cannot stand by itself. (usually lacks a verb of being, is a depe...

test for how many valence electrons in outermost electron shell.

**Grammar**

the answer is B reason why is because if we get rid of "for various classes" which is a prepositional phrase so we do not need it for these grammar problems, we get the fee is/are different. Thus, since fee is singular, we get B or the fee for various class is differ...

**counting up method**

this is used many times for subtraction. lets take the example 198 - 46. 198 rounds up to 200, and 46 rounds up to 50. 200 - 50 = 150. However, thats not our answer. 198 = 200-2. so the answer would be -2 added to 150. Also, 46 is 50-4. So the answer would be another +4 to 150...

**Chemistry**

Know how many valence electrons there are in both of them, then make a test to find how many valence electrons in both of them.

BTW, A would be at the top if the right triangle were standing on its shorter base. C would be on the other side on the bottom right. B would be on the right angle

**Math**

sorry i dont see a picture. But, I'll explain what should be seen. Make a right triangle. From the angle <B, where B is 90 degrees, draw an altitude down to CA. Call that point D. We see that ABC and BCD are similar triangles. BC/CD=AC/BC, so BC^2=AC*CD. Likewise, ADB i...
