The price for an ounce of gold on september 23,2013,was $1,326.40. a group of 10 friends decide to equally share the cost of 1 ounce of gold. how many money will each friend pay?

Each friend will pay a sum of $132.64.

To determine the total sum each friend will pay the ounce of gold, the total cost of that ounce of gold (1326.40) will be divided by the total number of that group of friends i.e. 1326.40 ÷ 10

Therefore,

=

= 132.64

Hence, the total sum each friend would pay is $132.64.

The mathematical expression given above is a typical number problem, which was solved through the usage of Division, which is one of the functions of BODMAS.

Division has to do with splitting or dividing of two or more numerical values in order to derive different equal parts.  

And in this case, it can be observed that the usage of Division help determine the equal amount of money each friend would pay for that ounce  of gold.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
