First find the common factor of -30 and 75, which is 15.

Next find the common factors of the variables:

The factors of x$6 is x*x*x*x

Factor for y is y

Factors for Z^3 is z*z*z

Factors for Z^2 is z*z

The GCF would be x^4z^2

Final answer = 15x^4z^2

Answer:

15x^4z^2

Step-by-step explanation:

We need to break each term into the smallest factors

30 = 3*10 = 3*2*5

75 = 3*25 = 3*5*5

-30 x^4yz^3 = -3*2*5 * xxxxyzzz

75 x^4z^2 = 5*5*3xxxxzz

What common factors are in each term

3*5*xxxx*zz

15x^4z^2

Twelve more than half of a number is equal to the number

tester [92]

Let's consider that number to be 'x'..
So, twice the number (2x) is 12 greater than than the half of the number.
So the equation will be like,
2x=12+x/2
Solving this further,
2x=(24+x)/2
=> 4x=24+x
=>4x-x=24
=>3x=24
=>x=8..
So the number is "8".

1/5x-8=4. what does x. equal

Slav-nsk [51]

Answer:

Step-by-step explanation:

if you multiply everything by 5, then you can get rid of the fraction and the equation would now look like this:

x - 40 = 20

and now you can answer this simply

x - 40 = 20

+40 +40

x = 60

and since you multiplied 5 beforehand, now you have to divide by 5 to get the real answer

60 ÷ 5 = 12

therefore, x = 12

Answer:

If the question you are asking looks like this (5x*8x)(-3+9) then the answer is 240xsquared so the tiny 2 would be over the x

What is the value of x?

GrogVix [38]

Answer:

Step-by-step explanation:

The two triangles $\triangle MNP\sim \triangle RST$ .

Therefore the corresponding sides are proportional.

$\frac{|ST|}{|PN|} =\frac{|TR|}{|MP|}$

From the diagram |MP|=4, |PN|=3, |MN|=5 |ST|=x and |TR|=12.

Let us substitute the values and solve for x.

$\frac{12}{4}=\frac{x}{3}$

Multiply both sides by 3 to get:

$3*\frac{12}{4}=\frac{x}{3}*3$

This implies that:

$9=x$

Therefore x=9
