Find the inverse variation equation if x equals 5 when y equals 9?
The equation is xy = 5*9 = 45 Alternatively, y = 45/x
How do you solve X over 4 equals -9?

If y varies inversely as the square of x and y equals 5 when x equals 2.5 what is the value of y when x equals 9?
So 5 = (xy)^2 and x = 2.5. This means that 5 = (2.5y)^2. So sqrt(5)/2.5 = y when x = 2.5. Now if x = 9 then 5 = (9y)^2. So sqrt(5)/9 = y. This means that for any x in this relation y = sqrt(5)/x.
X over 5 equals 8 over 21 solve for x?
x/5 = 8/21 x = 8/21 * 5 x = 1.904761905
How do you solve x over 5 equals 3?
x/5 = 3 Multiply both sides by 5 to find the value of x:- x = 15
What is 5 over 9 equals 5 over x?
x=9
Solve the proportion 5 over 9 equals x over 27?
5/9=x/27 135=9x 15=x
How do you write multiplication problems in algebra?
For example 5x \ 9 x 5 + 10 + 72 = 9 So you move 72 over to 9 and minus it 5x / 9 x 5 + 10 = 9-72 Then bring 10 over 5x / 9 x 5 = -63- 10 Then brong 5 over 5x / 9 equals - 73 5x equals -73 times 9 5x equals 146 X equals to 146 divide by 5 Thanks you Hello Israel
What is -32 times 5 over 9?
-32 x 5/9 equals -17 7/9
What is the answer to 8 over 15 plus 2 over 9?
The LCF is 45 because 15 x 3 equals 45 and 9 x 5 equals 45. Now, multiply 8 x 3 to get 24 and 2 x 5 equals 10. 24 plus 10 equals 34. The answer is 34 over 45.
What the answers to x-9 equals 5?
x-9 = 5 x = 5+9 x = 14
What does x equal in the equation x plus 9 in brackets over 5 equals 4?
x = 11 (x+9)/5 = 4 x + 9 = 20 (multiply both sides by 5) x = 11
What is the value of x over y when x equals nine fourths and y equals three fifths?
x/y = (9/4) / (3/5) = (9/4) * (5/3) = (9*5)/(4*3) = 45/12 = 15/4
What is x if x over 5 plus 9 equals 4?
x = (-25) x/5 + 9 = 4 (multiply both sides by 5) x + 45 = 20 x = -25 Checking: (-25)/5 + 9 = 4 gives -5 + 9 = 4 correct
How do you answer 3over 5 equals x plus 2over 15?
3 over 5 is the same as 9 over 15 so x = 7 over 15.
How do you solve x plus 6 over 2 equals 9 over 5?
x+6/2 = 9/5 Start x+3 = 9/5 Simplify 6/2 into 3 x + 3 = 1.8 Simplify 9/5 into 1.8 x = 1.2 Subtract 1.8 from 3 (or x = 6/5)
What is the value of x over 9 equals 1?
x=9
