2z plus 9.75-7z equals -5.15?
2z+9.75-7z=-5.15
What is the only value z for which 6z - 24 equals 2z plus 50?
z = 18.5 6z - 24 = 2z + 50 Take the -24 to the other side of the equals and change its sign; take the 2z to the other side of the equals and change its sign: => 6z - 2z = 50 + 24 => 4z = 74 Divide both sides by 4: => z = 18.5
What is the value for z for which z over 3 plus 3 equals 2z - 3?
z = 3.6
Solve this system of equations 5x plus 3y plus z equals -29 x-3y plus 2z equals 23 14x-2y plus 3z equals -18?
Solve this system of equations. 5x+3y+z=-29 x-3y+2z=23 14x-2y+3z=-18 Write the solution as an ordered triple.
Find the solution to the system of equations 3x plus y plus z equals 6 3x - y plus 2z equals 9 y plus z equals 3?
3x + y + z = 63x - y + 2z = 9y + z = 3y + z = 3y = 3 - z (substitute 3 - z for y into the first equation of the system)3x + y + z = 63x + (3 - z) + z = 63x + 3 = 63x = 3x = 1 (substitute 3 - z for y and 1 for x into the second equation of the system)3x - y + 2z = 93(1) - (3 - z) + 2z = 93 - 3 + z + 2z = 93z = 9z = 3 (which yields y = 0)y = 3 - z = 3 - 3 = 0So that solution of the system of the equations is x = 1, y = 0, and z = 3.
-3 X -2Z - 7 equals?
(-3) x (-2z - 7) = 6z + 21 = 3 (2z + 7)
How do you solve 2 z -5 equals 11?
2z - 5 = 11 Add 5 to both sides: 2z = 16 Divide both sides by 2: z = 8
2z plus 9.75-7z equals -5.15?
2z+9.75-7z=-5.15
what is 16z-24=8(2z-3)=?
16(2z-3)
What Given that x equals 6 is solution to 5jx plus z equals 3 evalutate the expression 60j plus 2z?
60j + 2z = 6
Ifx equals y equals 2z then what is the value of x?
y and ½z
What is the only value z for which 6z - 24 equals 2z plus 50?
z = 18.5 6z - 24 = 2z + 50 Take the -24 to the other side of the equals and change its sign; take the 2z to the other side of the equals and change its sign: => 6z - 2z = 50 + 24 => 4z = 74 Divide both sides by 4: => z = 18.5
If x equals y equals 2z and xyz equals 256 then what is the value of x?
8
What is the absolute value of 2z-3 equals 0?
2z-3 equalls 0 and 2z equalls 3 and z equalls 3/2 therefore z = 1.5
What is 2z plus 17 equals 21?
2z+17=21 subtract 17 from both sides. 2z=4 divide both sides by 2 z=2
What is 2z 9.75-7z-5.15?
The answer to 2Z plus 9.75 subtract 7Z subtract equals 14.90. This is a math problem.
What is the solution to 2z-7 equals 13?
2z-7=13 +7 +7 add 7 to each side2z=20/2 /2 divide each side by 2z=10 is your answer
