Answer: 1.23×10¹⁶

Step-by-step explanation:

For this problem, we want to use order of operations to solve.

Parenthesis

Exponent

Multiply

Divide

Add

Subtract

Let's first solve the parenthesis.

(9*\frac{999999999}{9+9+9+9+9+9+9+9+9} )^2                [add denominator]

(9*\frac{999999999}{81} )^2                                  [cross multiply]

(\frac{999999999}{9} )^2                                       [divide]

(111111111)^2                                     [exponent]

1.23×10¹⁶

The ending result is way too large. Therefore, we use scientific notation and get 1.23×10¹⁶.

Click on the picture to look at some equivalent fractions. Look at them closely. Can you see a relationship of any kind between
Vera_Pavlovna [14]

when you simplify 2/4 it equals 1/2. Making them both equal the same.


2/3 when you double the numbers to make a bigger fraction you make 4/6.

2x2 = 4/ 3x3= /6 = 4/6


3/9 simplified is 1/3. Three goes into three one time, making the top one and three goes into 9 three times making the bottom 3.


When 9/12 is rounded down it is equivalent to 3/4

Answer:

f(x) =  \frac{x + 7}{6 - x}  \\  \frac{3}{2}  =  \frac{x + 7}{6 - x}  \\ 3(6 - x) = 2(x + 7) \\ 18 - 3x = 2x + 14 \\  - 3x - 2x = 14 - 18 \\  - 5x =  - 4 \\  \frac{ - 5x}{ - 5}  =   \frac{ - 4}{ - 5}  \\ x =  \frac{4}{5}
