15z+5+6z=0 21z+5=0 z=-5/21
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
The list of choices that accompanies the question is really short.2x + 3y + 6z = 54At the y-intercept, 'x' and 'z' are zero.3y = 54y = 18
The quotient of 4 and 5 is 4 divided by 5, which equals 0.8. The product of 6 and z is 6z. When the quotient of 4 and 5 (0.8) is added to the product of 6 and z (6z), the expression becomes 0.8 + 6z.
6z =
6z + 28 = 12z + 10 18 = 6z 3 = z
15z+5+6z=0 21z+5=0 z=-5/21
6z+28=12z+10 6z-12z=10-28 addition property of equality. -6z=-18 simplification z=3 multiplication property of equality.
Is an equation of a straight line in 3 dimensions. It cannot be simplified further, and a solution for any of the variables requires another two [independent] equations.
2z+6z+24=0 8z+24=0 8z= -24 z= - 3
1 plus 6 zeroes equals 1 million (1,000,000).
-6z + 2 = 3z + 4z + 28 Add 6z to both sides: 2 = 3z + 4z + 28 + 6z = 28 + 13z Subtract 28 from both sides: - 26 = 13z Divide both sides by 13: -2 = z
-6z + 16 = 52 subtract 16 from each side -6z = 36 divide by -6 z = -6
63 + 20 - 60 = 23
-6z 2 = 3z+ 4z+28 -6z+2 +3z = 3z+ 4z +28 +4z -6z+4z+2 = 3z+ 28 -10z+2 -3z= 28 - 2 -10z + -3z = 26 -13z/13 = 26/-13 z = -2
-5x+7y-6z
6z - 8 - 2 + 3 = 0 combining all the constant terms: 6z -7 = 0 adding 7 to both sides: 6z = 7 dividing both sides by 6: z = 7/6
