Answer:

Solution for 2z-4=12-1z equation:

Simplifying

2z + -4 = 12 + -1z

Reorder the terms:

-4 + 2z = 12 + -1z

Solving

-4 + 2z = 12 + -1z

Solving for variable 'z'.

Move all terms containing z to the left, all other terms to the right.

Add 'z' to each side of the equation.

-4 + 2z + z = 12 + -1z + z

Combine like terms: 2z + z = 3z

-4 + 3z = 12 + -1z + z

Combine like terms: -1z + z = 0

-4 + 3z = 12 + 0

-4 + 3z = 12

Add '4' to each side of the equation.

-4 + 4 + 3z = 12 + 4

Combine like terms: -4 + 4 = 0

0 + 3z = 12 + 4

3z = 12 + 4

Combine like terms: 12 + 4 = 16

3z = 16

Divide each side by '3'.

z = 5.333333333

Simplifying

z = 5.333333333

Answer:

z = 8

Step-by-step explanation:

Collect like terms

1z - 4 = 4

Add 4 to both sides

1z = 8

Divide both sides by 1

z = 8

Answer: 411.6

Step-by-step explanation: What is 411.6 Million in Scientific Notation?

To answer the question what is 411.6 million in scientific notation let’s recall how to convert 411,600,000 to scientific notation as detailed on our home page.

If you split the number 411600000 into a coefficient and a power of 10 you do get 411.6 million in exponential form, but there is an indefinite number of possibilities.

As you probably want 411.6 million in normalized scientific notation, the coefficient or significand of 411.6m in scientific notation must be in the interval [1,10[.

As there are many ways to express 411.6 million in scientific notation, in this post we mean 411.6 million in normalized scientific notation, unless stated otherwise.
