Answer:

the answer to this question is A. 4/5

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced problems involving fractions.

In order to get a better view of the problem we should convert the whole numbers into fractions as well. We do this by multiplying the whole number by the denominator and then adding it to the numerator like so,

\frac{(7*5)+1}{5} -\frac{(6*5)+2}{5}

\frac{36}{5} -\frac{32}{5}

Now that everything is in the form of a fraction with a common denominator, we can simply subtract both numerators together to get an answer.

\frac{36}{5} -\frac{32}{5}= x

\frac{36-32}{5}= x

\frac{4}{5}= x

Finally, we can see that the answer to this question is A. 4/5

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Minchanka [31]

Answer:

No.

Step-by-step explanation:

The equipment wll save $35,000 per over for 10 years, which totals to $350,000.

If the equipment is bought on a simple interest rate of 12% annually for ten years, it will cost:

A = P (1 + rt),\\where\ A =\ Final\ amount,\ r=rate\of\interest\annually,\ t=time,\ P= Principal\ value\\\\P = 200,000r = 0.12t = 10 \\\\A = 200,000 ( 1 + 0.12\times 10)\\A = 200,000 (1 + 1.2)\\A = 200,000 (2.2)\\A = 440,000

We will need to pay $440,000 in total for the machine in over ten years.

If we compare both values, it can be deduced that industrial equipment is more expensive than labor cost.

1/2= ?/8+3/?=?/12<br> find the missing number to make these fractions equal.
azamat

Answer:

  (1, 8, 6) or (2, 12, 6) or (3, 24, 6)

Step-by-step explanation:

The last number must be 6:

  1/2 = 6/12

The other two numbers cannot be 6, but can have several values:

  1/2 = 1/8 +3/8 = 6/12

  1/2 = 2/8 +3/12 = 6/12

  1/2 = 3/8 +3/24 = 6/12

__

There are a variety of negative solutions as well. For example, ...

  1/2 = -8/8 +3/2 = 6/12

7 + x/5 = -4<br> What is x?
Dafna1 [17]

Answer:

x = -55

Step-by-step explanation:

Subtract 7 on both sides first to get to this equation, x/5 = -11.  Since there is a fraction on the left side, you have to multiply 5 on both sides to get your x-value which is -55.

Un vendedor de frutas tiene cierto número de mangos, vende 3/5 de ellos más dos mangos; luego vende 1/3 de los restantes más dos
valkas [14]

Respuesta:

200 mangos

Explicación paso a paso:

Dado :

Sea el número inicial de mangos = x

Primera venta:

3 / 5x + 2

Número a la izquierda = x - (3 / 5x + 2) = 2 / 5x - 2

Segunda venta:

1/3 (2 / 5x - 2) + 2 = 2 / 15x - 2/3 + 2

Cantidad restante:

2 / 5x - 2 - (2 / 15x - 2/3 +2)

2 / 5x - 2 - 2 / 15x + 2/3 - 2

0,2666666x - 3,3333

Tercera venta:

1/2 (0,2666666x - 3,3333) + 1 = 0,133333x - 1,666665 + 1

0.2666666x - 3.3333 - (0.133333x - 1.666665 + 1) = venta final

0,2666666x - 3,3333 - (0,133333x - 1,666665 + 1) = 24

0,2666666x - 3,3333 - 0,133333x + 1,666665 - 1 = 24

0,133333x - 2,666635 = 24

0.133333x = 24 + 2.666635

0,133333x = 26,666635

x = 26,666635 / 0,133333

x = 200.00026

x = 200 mangos
