5/21 X 14/25 - Algebra Homework Help
My solution will be, I will use cancelation. First find one numerator and one denominator that can be divided by a number. For this I found 2 pairs. 21 and 14,5 and 25. Then divide 14 and 21 by 7. The result is 2 and 3. Then divide 5 and 25 by 5. The result is 1 and 5. With that the new fractions are 1/3 and 2/5.
SOLUTION: Solve by the addition method. (If there is no solution, …
Use the parameters x and y as necessary.) x + 5y=11 2x + 7y=13 Algebra -> Coordinate Systems and Linear Equations -> SOLUTION: Solve by the addition method. (If there is no solution, enter NO SOLUTION.
SOLUTION: The cost of printing digital pictures is given by y
the relationship between x and y is a function because each and every value of x results in one and only one distinct value of y. in function notation, y = .13 * x is written as f(x) = .13 * x f(5) replaces x with 5 to get f(5) = .13 * 5 = .65 it tells you to evaluate the function when x = 5. x = 5 means you printed 5 digital pictures.
SOLUTION: Find the exact value of sin(cos^-1(12/13)+sin^-1(3/5))
sin^-1(5/13), => sinA = 5/13 and cos^-1(3/5) => cosB = 3/5. sinA and cosB are positive sinA = sqrt{1 - cos^2A} sinA = sqrt{1 - (5/13)^2} sinA = sqrt{1 - 25/169} sinA = sqrt{144/169} sinA = 12/13 ----- . cosB = sqrt{1 - sin^2B} cosB = sqrt{1 - (3/5)^2} cosB = sqrt{1 - 9/25} cosB = sqrt{16/25} cosB = 4/5 ----- sin(A + B) = sinA cosB + cosAsinB ...

Question 1195439: Assume that a procedure yields a binomial distribution with a trial repeated n = 30 times. . Use the binomial probability formula to find the probability of x = 5 successes given the probability p = 1/4 of success on a single tr
SOLUTION: Please help me solve this inequality? (x+13)(x …
You can put this solution on YOUR website! (x+13)(x-13)(x+7)>0 x+13>0 x>-13 ans. x-13>0 x>13 ans. x+7>0 x>-7 ans. ...
SOLUTION: system by substitution x+3y=13 3x+5y=19 i can't …
First we will distribute the 3 to both 13 and -3y. 39 - 9y + 5y = 19 Combine like terms. 39 - 4y = 19 Subtract 39 from both sides of the equation to isolate the y. -4y = -20 Isolate the y further by dividing both sides of the equation by -4. y = 5 Now we can substitute y in the first equation to find x. x + 3(5) = 13 x + 15 = 13 Isolate the x ...
SOLUTION: If sin x = {{{12/13}}} where {{{pi/2 <= x <= pi ...
You can put this solution on YOUR website! If sin x =12/13, where pi/2 = x = pi, determine: a) sin (x/2) b) sec (x/2)
