first number = X+8

third number X/3

sum of three numbers is 50.

Asap please i need answer
vesna_86 [32]

Answer:

Step-by-step explanation:

2) 8=n+3/-2

we cross multiply

n+3=8*(-2)

n+3= -16

n= -16 - 3

n= -19

lets check if we are correct

8=-19+3/-2

8= -16/-2

-16/-2=8

4) 9=x/2+6

we first calculate the fraction

x/2+6

L. c. m is 2

x/2+6/1=4x + 8/2=12x/2

2 times 2=4 plus  x = 4x

2 times 1 =2 plus 6= 8

thats how i got 4x + 8/2

back to the question

9=12x/2

cross multiply

12x=9*2

12x=18

x=18/12

we will use 2 to divide it

9/2

3 will divide

3/2

x=3/2

Nitella [24]

Answer:

Purchases made during the year is $1300.

Step-by-step explanation:

The beginning Inventory is reported to be $3900

The ending inventory is reported to be $1400

The cost of goods sold, (Sales) is reported to be $3800

We can relate the above mentioned items using the formula

Ending Inventory  = Beginning Inventory + Purchases - Sales

      $1400               = $3900 +  Purchases - $3800

Therefore the amount of purchase made during the year,

Purchases  = $1400  - $100

                   = $1300.
