What is 9.33 as a fraction
kvv77 [185]
Well,

We can read 9.33 as 9 and 33 hundredths.

In fraction form that would be:
9  \frac{33}{100}

That is already simplest form.

If you meant 9. \overline{3}, then it would be:
9  \frac{1}{3}

G(x)=27x^3+125
Darya [45]

Answer:

The answer to your question is: (3x + 5)(9x² - 15x + 25)

Step-by-step explanation:

Data

G(x) = 27x³ + 125

This is a sum of cubes

Process

\sqrt[3]{27} = 3

\sqrt[3]{125} = 5

      27x³ + 125 = (3x)³ + (5)³ = (3x + 5)(9x² - 15x + 25)

2.5x + 1.5 = 4x - 11 what is x
Alexeev081 [22]

Answer:

X = 8.3 (shortened)

<u>Steps for answer!</u>

1. Subtract 2.5x from both sides.

1.5=4x-11-2.5x

2. Simplify  4x-11-2.5 to  1.5x-11

1.5=1.5x-11

3. Add 11 to both sides.

1.5+11=1.5x

4. Simplify  1.5+11 to 12.5.

12.5=1.5x

5. Divide both sides by 1.5.

12.5/1.5=x

6. Simplify  12.5/1.5 to  8.3333338.333333.

8.333333=x

7. Switch sides.

x=8.333333
