1- start with the original equation

x=2y+70

Let y =3x

x=2x 3x+70

simplify

x=6x+70

2-solve for x.

x=6x+70

Subtract 6x from both sides

x-6x=70

simplify x-6x to -5x

-5x=70

divide both sides by -5

x=- 70/5

simplify 70/5 to 14

x=-14

3- start with an original equation .

y=3x

Let x =-14

y=3x -14

simplify

y=-42

therefore

x=-14

y=-42

HELP PLEASE I NEED THIS DONE ASAP
Nata [24]

a). 0.45 with a line over the 45 means 0.45454545454545... forever.

It's equivalent to  45/99  which is  <em>5/11</em> .

b). 0.45 with a line over the 5 means 0.455555555... forever.

It's equivalent to (0.4 + 0.555555.../10)

The 0.4 part is  4/10

The 0.5555555555.../10 part is  5/90 .

(4/10) + (5/90) = <em>41/90 </em>

c). 0.45 means 45/100 .  That's <em> 9/20</em> .

The following is an account for a production department, showing its costs for one month:
deff fn [24]

Answer:

option (b)  $9,360

Step-by-step explanation:

Given:

Goods in Process Inventory

Balance = $6,300

Direct materials = $22,500

Direct labor = $17,100

Overhead = $11,700

The cost of units in ending goods in process inventory = $5,490

The cost of started and completed units = $42,750

Now,

The cost of total Goods in Process Inventory will be

= Balance + Direct materials + Direct labor + Overhead

= $6,300 + $22,500 + $17,100 + $11,700

= $57,600

also,

Cost of units to be transferred out

= cost of total Goods in Process Inventory - ( cost of units in ending goods in process inventory )

= $57,600 - $5,490

= $52,110

Thus,

Cost of Completed Goods in Beginning Inventory

= Cost of units to be transferred out - cost of started and completed units

= $52,110 - $42,750

= $9,360

Hence, the answer is option (b)  $9,360
