Cloud [144]

Biweekly salary last year algebraically will be S = (27)A.  Semimonthly salary this year algebraically will be S = ( A + R )6.

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Last year, Andrea's annual salary was A dollar and she was paid biweekly. This year she received a raise of R dollars per year. She is now paid semimonthly.

Biweekly salary last year algebraically will be:-

S = (27)A.

Semimonthly salary this year algebraically will be:-

S = ( A + R )6.

Therefore, the biweekly salary last year algebraically will be S = (27)A.  Semimonthly salary this year algebraically will be S = ( A + R )6.

Write the equation in standard form for the circle with center (-7,0) and radius 3√3.
mario62 [17]

Answer: (x +7)^2 + y^2 = 27

Step-by-step explanation:

The standard form of a circle is written as such:

(x - h)^2 + (y - k)^2 = r^2

Where (h, k) is the center of the circle, and r is the radius.

We know that the center is (-7, 0), so we can plug that into the equation like this: (x +7)^2 + y^2 = r^2

The radius is 3 * the square root of 3. To square this, we can multiply 3 squared and the square root of 3 squared:

3^2 * \sqrt{3} ^2 = 9 * 3

So, your standard form equation is the following:

(x +7)^2 + y^2 = 27

Solve for x:<br> -3(2x+1) + 3x = 6x + 3<br> Help!!
djverab [1.8K]

Answer:

b  x =-2/3

Step-by-step explanation:

-3(2x+1) + 3x = 6x + 3

Distribute

-6x -3 +3x =6x+3

Combine like terms

-3x-3 = 6x+3

Add 3x to each side

-3x+3x-3 = 6x+3x+3

-3 = 9x+3

Subtract 3 from each side

-3-3 = 9x+3-3

-6 = 9x

Divide by 9

-6/9 = 9x/9

-2/3 =x
