What is 8/12=8/12= in simplest form

Problem 1 (on the left)

We can solve for y in the second equation since the coefficient here is 1.

Having coefficients that aren't -1 or 1 means we'd likely end up with fractions.

Add 5x to both sides like so:

y - 5x = 19

y = 5x+19

Now plug this into the first equation.

-3x - 8y = 20

-3x - 8( y ) = 20

-3x - 8( 5x+19 ) = 20

At this point, we have only one variable.

We stop here because your teacher does not want you to solve the final equation.

-------------------

Answers:

Variable to isolate: y

It leads to y = 5x+19 after solving the second equation for y.

And further leads to -3x - 8( 5x+19 ) = 20 after substitution.

======================================================

Problem 2 (on the right)

This time we can solve for x in the second equation. The reasoning is the same (coefficient of 1). Subtract 3y from both sides to get:

x+3y = 1

x = -3y+1

Substitute this into first equation.

Everywhere you see an x, replace it with -3y+1.

-3x - 3y = -15

-3( x ) - 3y = -15

-3( -3y+1 ) - 3y = -15

Like before, we now have one variable left.

-------------------

Answers:

Variable to isolate: x

It leads to x = -3y+1 when you solve for x in the second equation.

And further leads to -3( -3y+1 ) - 3y = -15  after substitution.

Answer:

180 degrees

Step-by-step explanation:

The triangle ABC is rotated by 180 degrees.

A triangle in geometry is a three-sided polygon with three edges and three vertices.

As per the given data:

We are given the diagram of a triangle on a graph and the diagram of its image after rotation also.

We have to find out that by what degrees the triangle ABC is rotated about the origin counterclockwise.

Furthermore, we can clearly see that the shape of the triangle is flipped about the origin, hence we can easily understand that the triangle is rotated by 180 degrees only, because if it's rotated by any other angle than 180 degrees it will not look like it's flipped rather it would look like unsymmetrical transformation about the origin.

The triangle ABC is rotated by 180 degrees.

Hence, The triangle ABC is rotated by 180 degrees.

The approximate the value of x in the equation -16 * 10⁶ˣ = -80 is 0.116.

An equation is an expression that shows the relationship between two or more variables and numbers.

Given the equation:

-16 * 10⁶ˣ = -80

Dividing both sides by -16:

10⁶ˣ = 5

Taking ln of both sides:

6xln(10) = ln(5)

Finding the value of x:

x = 0.116

Terms, coefficients and factors are what make up an algebraic expression

The expression is given as:

(39.87 + 2(x-5))(1/2)

For an expression ab, the factors are a and b.

Hence, the factors of the expression (39.87 + 2(x-5))(1/2) are 39.87 + 2(x-5) and (1/2)

In (a), we have the first factor to be:

(39.87 + 2(x-5))

For an expression a + b, the terms are a and b

Hence, the terms in the first factor are 39.87 and 2(x-5)

In (b), we have the second term to be 2(x - 5)

For an expression 5a, the coefficient is 5

Hence, the coefficient in the second term of the first factor is 2

This question discusses Payroll Administration and Management.

Please note that based on the information provided, the weekly gross is K 6,860 the Net Pay is K 4,957  while the monthly Net Pay is K19,828.00.

Payroll Administration and Management is the activity involved in making sure that the compensation and benefits of the employee for the period that they have spent working are well organized, computed, and administered.

The steps to the solution is given below:

1) Note that the information given above is for one week.

The rate per hour is: K125/Hour.

The rate for overtime is 1.5 of the normal rate

Performance Bonus is K45 for every 50 units.

Given the above, the gross pay for the week is:

Normal Pay + Overtime Pay + Performance Bonus Pay.

a) Normal Pay is given as 125 * 40 = K5,000

b) Overtime Pay is given as (125*1.5) * 8 = K 1,500

c) Performance bonus is given as 45 * (400/50) = K360

d) Total Gross therefore is given as 5,000 + 1,500 + 360 = K 6,860

If gross pay is $6,860, Net Pay is calculated by removing deductions.

Deductions are:

Pension fund = 7.5% of K 6,869 = K 514.5

PAYE Tax = 20% of (95% of 6,869) = K 1,310.24 This is because medical aid is non-taxable.

Employee Insurance = 1% of K 6,860= K 68.6

Union Membership = K 10

The Total Deduction, thus, is = 514.5 + 1,310.24 + 68.6 +10 = K 1,903.34

The Net pay =  Gross Pay Less Deductibles

= 6,860 - 1,903

Thus The Net pay = K 4,957 /Week.

Therefore, his monthly net wage will be:

4, 957* 4 = K19,828.00/Month

B) The kind of remuneration method used by company XYZ is

Time Rate System. Under the time rate system, the worker is paid per hour, per day, per week, or per month.

The cost would be at least $755.1302 to build the deck.

The deck is in the shape of a rectangle. Therefore,

where

l = length

w = width

length = 9.4 ft

width = 6.7 ft

area = 9.4 × 6.7 = 62.98 ft²

Therefore,

1 ft² of lumber = $11.99

62.98 ft² of lumber = ?
