Question:

How can I conjugate the verb comer in the present tense?

Erica T.

You can conjugate the verb comer in the present tense by first dropping the infinitive, er. We are then left with com-. Next, we can add the appropriate ending. yo = o tú = es él/ella/usted = e nosotros/nosotras = emos vosotros/vosotras = éis and ellos/ellas/ustedes = en Therefore, comer in the present tense would be, yo como, tú comes, él/ella/usted come, nosotros/nosotras comemos, vosotros/vosotras coméis, and ellos/ellas/ustedes comen.

Question:

How can I determine the number of neutrons an atom has?

Erica T.

The number of neutrons an atom has is equal to the mass number minus the number of protons. For example, Carbon has a mass number of about 12 and an atomic number of 6. The atomic number is equal to the number of protons. Therefore, the atomic mass, 12, minus the number of protons, 6, is equal to 6. Carbon has 6 neutrons.

Question:

How can I solve the equation 2+8(x-1)?

Erica T.

First, we must remember the order of operations to solve this equation. Multiplication must be done first. We need to multiply what is in parenthesis by 8. That would give us, 2+8x-8. Now, we can do the subtraction. 2-8=-6. Now our equation looks like, 8x-6. This is our final answer.
