Question:

Rewrite the following equation: 5 * 5 * 5* 5 * 5 *5

Jessica D.

Answer: 5 ^(6). When the same integer is multiplied by itself, the equation can be written as an exponent. 5 ^(6) is not the same as 5 multiplied by 6.

Question:

Solve for x: 2x + 10 =20

Jessica D.

X = 5. When solving for a single variable (x), isolate the X to one side of the equation. Therefore, first subtract 10 from 20. Now rewrite the equation as 2x = 20 - 10. Continue to solve. Now rewrite the equation: 2x = 10. Next in order to isolate X by itself, divide 2 on both sides. Rewrite the equation and solve: 2x/2 = 10/2 ---> x = 5. To check your work, use your answer back into the original problem. If both sides of the equation equal each other, the solution is correct. 2 (5) + 10 = 20. 10 + 10 = 20... 20 =20.

Question:

There are three subatomic particles in an atom. The particle that has a positive charge is?

Jessica D.

Proton. The three subatomic particles in an atom are protons, neutrons, and electrons. Protons and neutrons are found in the nucleus of the atom. Protons have a +1 charge and electrons have a -1 charge. Neutrons have a neutral charge while electrons have a negative charge. Electrons exist outside of the nucleus and orbit the nucleus of the atom.
