What is the solution to the equation x/2-4=6​

Mathematics
2 answers:
eduard3 years ago

For this case we must find the value of "x" of the following equation:

\frac {x} {2} -4 = 6

So:

We add 4 sides of the equation:

\frac {x} {2} = 6 + 4\\\frac {x} {2} = 10

We multiply by 2 on both sides of the equation:

x = 20

Thus, the value of the variable x is 20

Answer:

x = 20

<u>Answer</u>

x = 20

<u>Explanation</u>

Multiply the entire equation by 2 to get rid of the fraction.

x/2 * 2 = x

-4 * 2 = -8

6 * 2 = 12

Now, we have:

x - 8 = 12

To complete, add 8 to both sides

x = 20

A cafeteria manager needs to know how many apple and bananas to order. She asked students to choose either an apple or a banana
lilavasa [31]

Answer:

  48

Step-by-step explanation:

The fraction who picked apples is the rest of the students:

  1 - 5/8 = 3/8

of them.

So the number who picked apples relative to the number who picked bananas is ...

  apples/bananas = (3/8)/(5/8) = 3/5

Multiplying this by the number who picked bananas gives the number who picked apples:

  apples = bananas · 3/5 = 80·3/5 = 48

48 students picked apples.

____

<em>Alternate solution</em>

Let "a" represent the number who picked apples. The ratio of banana choosers to the total is 5/8, and there were 80 who chose bananas. That gives rise to the equation ...

  80/(80 +a) = 5/8

  640 = 400 +5a . . . . . . multiply by 8(80+a) and simplify

  240 = 5a . . . . . . . . . . . subtract 400

  240/5 = a = 48 . . . . . . divide by 5

48 students picked apples.

If a total of 780 joules of energy is lost by
ankoles [38]

If a total of 780 joules of energy is lost by  25.0 grams of this substance, the heat of fusion is 31.2 J/g

The energy lost, H  =  780 Joules

Mass of the substance, m = 25.0 grams

The Energy lost is the product of mass and the heat of fusion

The heat of fusion, c, is calculated using the equation below:

H   =  mc

Substitute H = 780 Joules and m = 25.0 grams into the equation

H   =  mc

780   =   25c

Divide both sides by 25

\frac{780}{25} = \frac{25c}{25}  \\c = 31.2 Joules/g

The heat of fusion of the substance is 31.2 J/g
