I'd like to help you, but I'm afraid I don't understand your question.

So I'm guessing we have

(16/27) ^(1/3) ??      If so......we can write

(2⁴/3³)^(1/3) =

(2/3)*(2)^(1/3)

Ok. Thank you. 

daugher is in precal/trig ....ive been out of this game a long time...was looking to provide a little help for her to understand....

Why do you need to know all this?

 960986781234.38924732689372091724983563829083

Equation??

Think of it like that, t for -sin x = 34.234234234676542478

Theoretically speaking it is 4.2477477477477477477477477477477477477477477(repeater) but do you want the answer or the way to calculate?

1/6 of 186 = 1/6*186 = 186/6 = 31.

-4(3-x) = 2(x+6)

Distribute the -4 & 2.

-12 + 4x = 2x + 12

Add 12 to both sides and subtract 2x from both sides.

2x = 24

Divide by 2.

x = 24/2 = 12.

2 1/3 --> convert to an improper fraction --> 2*3 + 1 / (3) --> 7/3 = 2.33

Now, convert 2.33 into a percentage by multiplying by 100 --> 2.33*100 = 233 (same as moving the decimal place 2 times to the right)

233% is your answer.

Thanks Alan for taking the time to write all that out. It pretty much explains it all for me!!

I think there is an error in one of the equations there in the book. I think he's made one negative when it shouldn't be or switched something around by mistake. It happened before with the other problem you helped me solve where he had reversed two figures and put them in the wrong sequence.

Easy done when dealing with all that data.

Thanks for all the help i appreciate it.

You change unlike denominators to like denominators by comparing the two denominators first:

You have 7/8 & 1/2...7/8 is fine, but 1/2 can be converted to something like #/8 [since 7/8 has 8 as its denominator] by multiplying both the numerator and denominator by 4 --> 1*4 / 2*4 = 4/8.

Now, we can easily subtract --> 7/8 - 4/8 = (7-4)/8 = 3/8.

Theoretically...the spinner should land on each one of the numbers 10 times.

And since there are three odd numbers, we should expect that the spinner should land on an odd number about 30 times.

Nos. 1 and 8 are on that previous post I sent to you....

4. "C' is correct

Multiply anything in the parentheses out: Ex. 4(3x - 2) = 12x - 8.

Collect "like" terms: Suppose we had 12x - 8 + 10x --> 22x - 8.

Cross out anything that is common in both the numerator and the denominator: 22x - 8 / 1(22x - 8) --> cross both (22x - 8) out and we are left with 1/1 = 1!

Ex. 5x^2y^2/(xy) --> we can cross 1 x and 1 y out leaving us with 5xy!

4[1+4(5x+2y)] =

4[1 + 20x + 8y] =

4 + 80x + 32y

Do you mean in scientific notation??  If so, we have

1.2 x 10¹

12 cant be written in exponential form!

See if the following help:

To solve these equations using this website's calculator enter the following in the vector/matrix section (Note, you only enter the values in the table part, not in the top line.  You also select the ^-1 next to the A):

Press the equals sign to get the following:

Hmmm!  Seems to be a sign error for I₂ here.

I'm sorry, but I don't understand your question......

.025% x 120 = .00025 x 120 =  .03

"A" is correct
