By Cross multiplying given equation will become.

3x-15= 2(4x)

3x -15= 8x

subtracting 3x both sides

3x-3x -15 = 8x-3x

-15 = 5x

Dividing 5 both sides

<u>-5= x   answer</u>

Help please I am a bit confused on this.
Anit [1.1K]

Because there are 4 inside angles the sum of the four angles must equal 360 degrees.

Add the angles to equal 360:

4x + 3x + 2x + 3x = 360

Simplify:

12x = 360

Solve for x by dividing both sides by 12:

x = 360 /12

x = 30

Now you have x, solve for each angle:

ABC = 4x = 4 x 30 = 120 degrees.

BCD = 3x = 3 x 30 = 90 degrees.

CDA = 2x = 2x 30 = 60 degrees.

DAB = 3x = 3 x 30 = 90 degrees.

C. It's important to know that a four sides figure needs the inside angles when added together need to equal 360 degrees.

SCORPION-xisa [38]

Answer:

The answer is "96.864 ml".

Step-by-step explanation:

In this question, the formula of \bold{CI = X \pm t \times s}.

( where X is the mean, t is the coefficient, and s is the mean difference error)

As a result, only 2.5% of containers might include less than 100 ml of volume, its trust coefficient could indeed be used in accordance with 95%, which is t=1.96.  

And it can take \pm \ 1.6 \ ml to have been the full value the standard infinite:  \to CI = 100 \pm (1.96 \times 1.6) \\\\

         = 100 \pm (3.136) \\\\

Consequently, if the standard error is  \pm \ 1.6 \ ml , a similar amount should be used to fill  

= 100 - 3.136 \\\\= 96.864 \ \ mL

Iron has a density of 7.9 g/cm³. Gold has a density of 19.3 g/cm³.
alexandr402 [8]
Density = m/v
3.86kg=3860g
d= 3860/200
= 19.3g/cm^3
therefore it is gold.

Labor rate = $7.50 per hour Labor time = 6.5 hours Retail price of parts = $0 Total job cost = $82.00 Overhead rate?
Ulleksa [173]
Total cost job=
Retail price of parts+labor cost+manufacturing overhead

Total cost job 82

Retail price of parts 0

Labor cost=7.5×6.5=48.75

Manufacturing overhead ?

82=0+48.75+?

?=82−48.75

?=33.25

Manufacturing overhead is 33.25

Now find manufacturing overhead rate from the cost of labor
33.25÷48.75=0.682×100=68.2%

The answer 68.2%
