Z= -1

6 + z/9 = 9 Therefore, z/9 = 3 3 x 9 = 27 Therefore, z = 27

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

It is: (81*9*64)+19 = 46,675

If Z = 3, then (9 + 7Z) = [ 9 + 7(3) ] = 9 + 21 = 30

xy + z = 9Subtract 'z' from each side:xy = 9 - zDivide each side by 'x':y = (9 - z) / x

5 you dummy

The value of z is 8 inches because 4*8*9 = 288 cubic inches

3x + 2 = 82

well you should start with 9z + 10 = 145 then balance the equation by collecting like terms 9z = 145 - 10 solve 9z = 135 then divide both sides by the number next to the variable. (in this case 9) so 9z/9 = 135/9 solve z = 15

If 3z/2 = 9 then the value of z is 6

z4-9=0 z4=9

75..... my math teacher would be so proud of me just kidding

If x = 2 and y = 3 and z = 6 then the value of w if w = xyz is 36. (2 times 3 times 6)

divide each side by 12; Z=9

questions like this make me want to cry......

7z+9 = 72 7z = 72-9 7z = 63 z = 9

Can you help with this equation? Thanks. Solve for x and y and z for the following. x plus y plus z equals 9 x plus 2y plus 3z equals 23 x plus 5y plus -3z equals -7

As x ∝ yz2 then x = kyz2 where k is a constant. Substituting the given figures, 40 = k*20*22 = 80k Then k = ½ and the formula is, x = ½yz2 So, x = ½ * 30 *32 = 135

yz means to multiply y times z. So you just replace the values, and do the multiplication.

y * (x-1) = z Express as x,divide both sides by y(x - 1) = z/yadd 1 on both sidesx = z/y + 1

What is the area under the normal curve between z equals 0.0 and z equals 2.0?

4z - 1 = 9 4z = 10 (add 1 to both sides) z = 2.5 (divide both sides by 4)
