Answer:

2(4 + 2z) = 8 + 4z

2(4 + 2z) = 0

z = -2

Step-by-step explanation:

How to solve:

2(4 + 2z)

Distribute:

2(4 + 2z)

2(4) + 2(2z)

Multiply:

2(4) + 2(2z)

8 + 4z

8 + 4z is the simplified expression.

How to solve:

2(4 + 2z) = 0

Distribute:

2(4 + 2z) = 0

2(4) + 2(2z) = 0

Multiply:

2(4) + 2(2z) = 0

8 + 4z = 0

Subtract 8 on both sides:

8 + 4z = 0

-8 -8

4z = -8

Divide by 4 on both sides:

4z = -8

/4 /4

z = -2

z = -2 is the answer if 0 is on the other side of the equal sign

Answer: It would be 8+4z because you can't add a variable.

The solution for this problem is:
$\frac{4}{9}(x + 3)=g \\ 4(x+3) = 9g \\ (x+3)= \frac{9g}{4} \\ x= \frac{9g}{4} -3$

12. An equation is shown. 8 1/2 - 3 1/? = 5 3/12<br>What is the value of the missing number?

weeeeeb [17]

Answer:

Step-by-step explanation:

Alright, lets get started.

$8\frac{1}{2}-3\frac{1}{?}=5\frac{3}{12}$

These are mixed number given.

Suppose the complete mixed number of second place is x.

Converting mixed numbers into fractions.

$\frac{17}{2}-x=\frac{63}{12}$

Adding x in both sides

$\frac{17}{2}=x+\frac{63}{12}$

$x=\frac{17}{2}-\frac{63}{12}$

Making common denominator

$x=\frac{102}{12}-\frac{63}{12}$

$x=\frac{39}{12}$

$x=\frac{13}{4}$

In mixed number form:

$x=3\frac{1}{4}$

So comparing with given equation, the '?' sign will be equal to 4.

Hence the answer is 4 : Answer

Hope it will help :)

Find all of the zeros

noname [10]

Answer:

{-3, -1, 1}

Step-by-step explanation:

Zeros refer to x-intercepts. X-intercepts are x values when y = 0. You can tell where they are by looking at where the line passes the x-axis.

Therefore, {-3, -1, 1} are the zeros.
