What is 9z plus 5z plus 6(z-3)?
It is 20z-18 when simplified
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
Solve the following system of equations x plus 2y -6 equals z 3y-2z equals 7 4 plus 3x equals 2y -5z?
x+2y-6=z -z -z x+2y-z-6=0 +6 +6 ---------> x+2y-z=6 3y-2z=7 ---------> 0x+3y-2z=7 4+3x=2y-5z -3x -3x ---------> -3x+2y-5z=4 Put them into a matrix, for x,y,z and their answers. Solve for [A]-1[B], and the answer comes to: x= 1.75, y= 1.5, and z= -1.25
Solve for z z over 12 equals -60?
72
Which expression represents the algebraic phrase the sum of negative three-eighths and four times x minus nine times z?
