X varies directly with y and inversely with z x equals 0.12 when y equals 12 and z equals 2 Find x when y equals 1200 and z equals 1?
x = 24
If xy plus y equals z then x equals?
xy + y = z xy = z - y (xy)/y = (z - y)/y x = (z - y)/y
X varies directly with y and inversely with z x equals 0.25 y equals 10 and z equals 20 find x when y is 20 and z is 10?

What is the x- value of x-2y plus z equals -9 3y-2z equals 4 2x plus y plus 5z equals -5?
x-(x-2y)+z=-9 3y-2z=4 2x+y+5z=-5 x-(x-2y)+z=-9 --distribute negative through bracket--> x-x+2y+z=-9 x-x+2y+z=-9 --combine like terms (x)--> 2y+z=-9 2y+z=-9 --isolate z--> z=-9-2y substitute z into second equation: 3y-2(-9-2y)=4 --multiply -2 through bracket--> 3y+18+4y=4 3y+18+4y=4 --subtract 18 from both sides--> 3y+4y=-14 3y+4y=-14 --combine like terms--> 7y=-14 7y=-14 --divide both sides by 7--> y=-2 Substitute value of y into simplified first equation: z=-9-2(-2) --multiply through the bracket--> z=-9+4 z=-9+4 --combine like terms--> z=-5 Substitute values of y and z into third equation: 2x+(-2)+5(-5)=-5 --multiply through brackets--> 2x-2-25=-5 2x-2-25=-5 --combine like terms--> 2x-27=-5 2x-27=-5 --add 27 to both sides--> 2x=22 2x=22 --divide both sides by 2--> x=11 x=11, y=-2, z=-5
X varies directly with y and inversely with z x equals 125 when y equals 5 and z equals 4 Find x when y equals 4 and z equals 5?
Given x=k1y and x=k2/z x=125 ,y=5 then k1=25 x=125 , z=4 then k2=125(4)=500 If y=4 ,z=5 then x=25y = 100
6 plus z over 9 equals 9?
6 + z/9 = 9 Therefore, z/9 = 3 3 x 9 = 27 Therefore, z = 27
What is 3Z equals 9 equals 15?
It's rare to see an equation with two equals signs. I'm guessing something else went in between 3z and 9. 3z + 9 = 15, then z = 2 3z - 9 = 15, then z = 8 3z x 9 = 15, then z = 5/9 3z/9 = 15, then z = 45
9 plus 7z for z equals 3?
If Z = 3, then (9 + 7Z) = [ 9 + 7(3) ] = 9 + 21 = 30
What is xy plus z equals 9 for y?
xy + z = 9Subtract 'z' from each side:xy = 9 - zDivide each side by 'x':y = (9 - z) / x
What does -12 z -9 equal to?
-3
What is the missing length 4 in z 9 in Volume equals 288 cubic inches z equals inches ?
The value of z is 8 inches because 4*8*9 = 288 cubic inches
If Negative 9 times z plus 4 equals Negative 5 what does z equal?
Z= -1
For x plus y plus z equals 9 2x-y-z equals -6 and x plus y-z equals 1 what is the echelon matrix?
3x + 2 = 82
What is z plus 4 equals 9?
5 you dummy
9 times z equals 135 what is z?
To find the value of z, set up the equation: 9z = 135 (then divide both sides of the equation by 9) z = 15
What is 3z divided by 2 which equals 9?
If 3z/2 = 9 then the value of z is 6
What is the answer of 6 plus z divided by 9 equals 9 solving for z?
75..... my math teacher would be so proud of me just kidding
