How do you turn 0.875 into a fraction

galina1969 [7]

Answer: 5/8

Step-by-step explanation:

0.875 is equal to 875/1000 because there are 3 decimal places, which is the amount of zeroes after the 1 as i like to think of it, and then to simplify it

875/1000 = 35/40 = 5/8

F(x)=2x^2-x-6 g(x)=4-x (f+g)(x)

Semenov [28]

$\large \boxed{(f + g)(x) = f(x) + g(x)}$

The property above is distribution property where we distribute x-term in the function.

Substitute both f(x) and g(x) in.

$\large{ \begin{cases} f(x) = 2 {x}^{2} - x - 6 \\ g(x) = 4 - x \end{cases}} \\ \large{f(x) + g(x) = (2 {x}^{2} - x - 6) + (4 - x)} \\ \large{f(x) + g(x) = 2 {x}^{2} - x - 6 + 4 - x}$

Évaluate/Combine like terms.

$\large{f(x) + g(x) = 2 {x}^{2} - 2x - 2}$

The function can be factored so there are two answers. (Both of them work as one of them is factored form while the other one is not.)

$\large{(f + g)(x) = 2 {x}^{2} -2x -2}$

<u>Alternative</u>

$\large{(f + g)(x) = 2({x}^{2} -x - 1)}$

<u>Answer</u>

(f+g)(x) = 2x²-2x-2
(f+g)(x) = 2(x²-x-1)

Both answers work. The second answer is in factored form.

Let me know if you have any doubts!

bill gets $0.05 for each can $0.20 for each glass bottle he returns to the recycling center yesterday he returned 32 cans and 10

solmaris [256]

32 x 0.05 ( because there are are 32 cans that are worth 5 cents each ) = 160 cents ($1.60)

Then:

10 x 0.20 ( 10 bottles that are worth 20 cents each ) = $2

Then plus them together

Answer = $3.60
