Hi pink_bubbles

Have a look at this solution
your question can be rewritten as
12 times (12q/12 + 4q/12 + 3q/12 -2q/12)
= 12 times of (12q+4q+3q-2q)/12
= 12 times 17q/12
=17q
If this makes you happy please give a rating

OK It is a little difficult trying to figure out the fractions you are trying to describe. Are there 3 fractions within the ( ) ? One with a denominator of 3, one with a denominator of 4, and one with a denominator of 6?

If so, the answer is 9q.

You must change the fractions within the ( ) to a common denominator, which would be 12. That would be 8q+3q-2q all over 12. Since it is all being multiplied by 12 outside the brackets, you just cancel the 12 outside and the 12 denominator inside which leaves the 8q+3q-2q which equals 11q-2q which equals 9q.

Thanks for using Fixya.

How do I do feet and inches calculations on the Casio FX-115ES Plus? For example, how can I do calculations like 10'-3" + 5'-4" + 11'-11" without having to convert the inches to feet?


You can combine all the feet together 10+5+11=26 feet
Combine all the inches together -3-4-11=-18 inches=-2 ft + 6 inches
26 ft -2ft +6 inches =24 ft +6 in=24.5 ft
You can also multiply each inch -value by 1/12
10-3/12+5-4/12+11-11/12=10+5+11 -(3+4+11)/12=26-18/12, continue

Ouku single din no sound from rca cables


Sorry I did not use the video out RCA cables. My audio RCA cables worked fine... I ran them to my JBL amplifier through a conversion adapter. I did not run it direct to the amp.. I used Metra TYTO-01 03-08 Toyota Vehicles Harness for JBL SYS (Ebay item 160560648718) and it worked great.

Here is the wiring color coding that I found online:

2x minus x cube plus 5x minus 2


Your question is interpreted in following way as it is not clear as cube of what & minus of what?
2x minus x cube plus 5 x minus 2

Solution 1:
= 2 x -1 x cube plus 5 x minus 2
= -2x cube plus 5 x minus 2
= cube of -2 plus 5 x minus 2
= (-8 +5) x -2
= -3 x -2
= 6

Solution2:
=2x-1x cube of +5 x -2
= -2 x 125 x -2
= 500

I think logically the solution 2 must be right. How you interpret the question is important.

Equation of line between to points


Example: Equation of the line through (1,5) and (3,6)
Calculate the slope (gradient) of the line as a=(y2-y1)/(x2-x1) where y2=6, y1=5, x2=3, and x1=1. You should get a=(6-5)/(3-1)=1/2
The equation is y=(1/2)x PLUS b, where b is not known yet.

To find b, substitute the coordinates of one of the points in the equation. Let us do it for (3,6).

The point (3,6) lies on the line, so 6=3/2 PLUS b.
Solve for b: 6 MINUS 3/2=b, or b=9/2=4.5
Equation is thus y=(x/2) PLUS 9/2 =(x PLUS 9)/2

Find an equation of the line containing the given pair of points (1,5)and(3,6)


Calculate the slope (gradient) of the line as a=(y2-y1)/(x2-x1) where y2=6, y1=5, x2=3, and x1=1. You should get a=(6-5)/(3-1)=1/2
The equation is y=(1/2)x PLUS b, where b is not known yet.

To find b, substitute the coordinates of one of the points in the equation. Let us do it for (3,6).

The point (3,6) lies on the line, so 6=3/2 PLUS b.
Solve for b: 6 MINUS 3/2=b, or b=9/2=4.5
Equation is thus y=(x/2) PLUS 9/2 =(x PLUS 9)/2

I have a Coleman Powermate portable gas 110 volt generator that engine runs but will not produce power. How do I recharge field?


Check where is the plus and minus of the field.
Take a 12 V battery. Connect the minus to the field minus.
Start the generator and just for a second connect the plus and disconnect.
The voltage should build up. If not check the AVR.

Err:syntax when I try to graph with ''-'' on ti-84 plus


Hello,
The calculator has two minus signs
  1. The regular MINUS sign which is used with the subtraction operation. This operation is binary, requiring two operands (two terms). In a-b, a and be are the operands (they very specific names, but I will skip this detail).
  2. The negation or change sign. This operation is called unary, requiring one operand. -a means take the negative of the number a.
These are the technicalities, in which you may not be interested. On calculators, the two operations are implemented differently, with two signs, the regular minus sign -- , and the change sign (-) usually smaller in size than the regular -- sign and raised above the main line.

Examples. Let (-) be the negation and -- the regular minus.
  • If you enter (-) 12 the TI84Plus accepts it and calculates the negative of 12.
  • If you enter 12 (-) 13 the TI protests with a syntax error
  • If you enter 12 ( (-) 13) the calculator interprets it as 12* (-13) and calculates -156.
  • If you enter --12, the calculator displays Ans--12, where Ans is the last result calculated. If Ans happens to be 0, the new result is obviously the one you are expecting. But if Ans holds a non zero value, this is incorrect.
Suppose you have to calculate X^(-2)*X^(-1/3)
You can enter it exactly as it is written above. In this case, you must use the change sign (-) in both factors.
You can also decide to use the power rules and enter the expression as X^( -2 --1/3). In this case the first minus is the negation and the second is the regular minus.

I could go on with a few more examples, but that will take us away from your present concern.

In short.
  1. If the minus sign is the leftmost (first) symbol in your function (after the Y1=) you should use the negation. Any subsequent minus should be the regular minus --
  2. If the minus sign is the first symbol in an exponent, you must use the negation. Any subsequent minus in the expression of an exponent should be the regular minus --
I hope it did not bore you death with details you do not care to know about. I do hope that it will help you prevent this type of syntax errors.

ok, connect the amp positive to the positive end of one sub coil, take the negative of that coil, and run it to the positive of the second sub coil, then run the negative out of the second sub coil to the negative of the amp.
