Question:

Please write out the preterite conjugations for the Spanish verb "ir". Include the subject.

Gloria R.

"Ir", which means "to go" is an irregular verb. In order to learn these, you will just need to keep studying. Repetition is key! As a refresher, preterite is one form of past tense in Spanish. Here's how we conjugate it: Yo fui. (I went) Tu fuiste. (You went) El/Ella fue. (He/she went) Nosotros fuimos. (We went) Vosotros fuisteis. (You all went) ** Ellos/Ellas/Ustedes fueron. (They all/You all went) **Most Spanish teachers don't require you to learn the vosotros form. I included it just in case you need it. Do you have any questions about this conjugation? Great job!

Question:

Please help me with this question: 12% of 145.6 is what? Round to the nearest hundredth.

Gloria R.

Great question! These questions used to trip me up a lot until I learned a couple really simple tricks. Turn this wordy problem into a simple mathematical formula question. Here's how: 1) When you see the % sign, you can automatically put the decimal point back to the 100th degree (back 2 times) and remove the % symbol. For example 12% = .12 2) when you see the word "of" in a math problem like that, you can replace "of" with "x" (multiply) For example: .12 x 145.6 is what 3) "Is" means "=" For example: .12 x 145.6 = what 4) Finally, the word "what" can be rewritten as "x" or any variable that you like. So let's rewrite this word problem as a simple equation: .12 x 145.6 = x 5) Now that looks easy, right?! Solve for x. x = 17.47 Good job! Do you have any questions about the answer or the explanation? Please let me know if there's anything you need clarified.

Question:

Subtract the polynomials: (9x^2 −4x+11)−(3x^2 −2x+2)

Gloria R.

Thank you for your question! The first thing you'll want to remember is that when you are subtracting polynomials, you'll want to carry the "-" through the entire polynomial that is in the parentheses. Step 1: −(3x^2 −2x+2) becomes: -3x^2+2x-2. Do you notice that what was "+" in the parentheses then becomes "-" and vice versa? Step 2: Rewrite the problem so that similar terms are next to each other. (9x^2 −4x + 11) − 3x^2 +2x - 2 can be re-written as: 9x^2 - 3x^2 -4x + 2x + 11 - 2 Step 3: Now we just combine the similar items! (Notice that we aren't changing any exponents. Just the number integer in front of the variables changes.) Let's break it down to the individual parts: 9x^2 - 3x^2 = 6x^2 -4x + 2x = -2x 11 - 2 = 9 Combine it all for the answer: 6x^2 -2x + 9 Do you have any questions or confusions about this answer or explanation? Good job!
