Arn't you the smart one Alan.      

3 - 4  =  3 + -4  =  -1

To add common fractions , you need a common denominator; a common denominator of 6 and 4 is 12, because both 6 and 4 divide into 12 without a remainder.  

Because 12 ÷ 6  =  2; multiplty 1/6 by 2/2.

Because 12 ÷ 4  =  3; multiply 1/4 by 3/3.

(1/6)x(2/2)  =  2/12

(1/4)x(3/3)  =  3/12

9 1/6 + 6 1/4     =     9 2/12 + 6 3/12    =     15 5/12    

     (Add the whole numbers together; add the fractions together.)

Factors are numbers or variables that are multiplied together.

9.25g + 4.10g - 2.05g

=  (9.25 + 4.10 - 2.05)g

=  11.3 g

Are you a new computer program?

To find the angle that creates a certain sin, use invSin:

  invSin( 0.119792 )  ≈  6.88°

To subtract fractions, they must both have the same denominator.

You can change 1/4 into a fraction if you multiply both the numerator and denominator by 2.

7/8 - (1/4)(2/2)

  =  7/8 - 2/8               Now subtract 2 from 7.

  =  5/8

You would solve it like this: Since we don't know the value of X, we leave the parenthesis alone. We then go to what's outside the parenthesis- -9-9. This would be -18. Then we can open the parenthesis and take the positive 9 out and add it to the -18 making it -9. Then we add 3x to all this and make it -9+3x. We cannot add this because the x after the 3. If it was -9x + 3x we could add it for -6

This isn't an equation; I think that you forgot part of the problem

The students in class a raised 20*($18) = $360

The students in class b raised twice as much each, so they raised .....24*($36) = $864

So the total raised was    $360 + $864 = $1224

Press the "2nd" button on the calculator and then hit the "asin" button and then enter your value...then, hit enter or "="

145+3 < 15x     adding on the left, we have

148 < 15x      divide both sides by 15

148/15 < x   or

x > 148/15

Let (x, y) be the other point.

So we have, using the mid-point formula......

(3 + x) /2 = 3.5      and   (-4 + y)/2 = -3       multipling both equations by 2 on both sides

3 + x = 7               and     -4 + y  = -6         and solving for x and y, we have

-3        -3                         +4          +4

      x = 4               and            y = -2

So the point is   (4, -2)

1. If two numbers have an absolute value of 16, one must be 16 and the other must be -16. So, clearly, 16 is the number greater than 12.

2. All the possible values for the point would be the positive numbers > 10. If the original point was < -10, all the absoulte values of such points would be > 10.

Use a caculator, there isnt a formula for square root.

1 1/5 is the fraction form of 1.2 as a mixed number. An improper fraction form would be 6/5.

The first answer is incorrect. You do not divide to find percentages. You multiply the number by the percentage in decimal form. 5% in decimal is .05.

So do 3600 * .05 = 180

1 1/5 or 6/5

3600 divided by 5 equals 720

2² = 4

So, the question now is:  Does the square root of 2 equal the cube root of 4?

Use a calculator to find both values and compare them. Are they equal?

"This is 5 times as much caffeine as in a 12 oz caffeinated soft drink"

"This" refers to the 184 mg of caffeine and so, in the equation, 184 will replace "this."

"is" is a verb and will be replace by an equal sign.

"5" remains 5.

"times" will be replaced by "·".

"as much ... drink" will be replaced by d.

184 = 5·d

3(7/12)  =  3/1 x 7/12  =  21/12  =  7/4

5/4 - 7/4  =  (5 - 7)/4  =  -2/4  =  -1/2

33% means 33 out of 100; so, divide 33 by 100 and write it as a decimal.

"of" means times.

To get the final answer, take the answer from above and multiply it times 34567.
