Answer:

c = 2

Step-by-step explanation:

Isolate the variable, c. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& roots)

Multiplications

Divisions

Additions

Subtractions

~

First, subtract 6 from both sides of the equation:

9c + 6 (-6) = 24 (-6)

9c = 24 - 6

9c = 18

Next, divide 9 from both sides of the equation:

(9c)/9 = (18)/9

c = 18/9

c = 2

c = 2 is your answer.

Answer:

{\boxed{\tt{c  =  2}}}

Step-by-step explanation:

<u>Concept</u> :

Here, we will use the below following steps to find a solution using the transposition method:

  • <u>Step 1</u> :- we will Identify the variables and constants in the given simple equation.
  • <u>Step 2</u> :- then we Simplify the equation in LHS and RHS.
  • <u>Step 3</u> :- Transpose or shift the term on the other side to solve the equation further simplest.
  • <u>Step 4</u> :- Simplify the equation using arithmetic operation as required that is mentioned in rule 1 or rule 2 of linear equations.
  • <u>Step 5</u> :- Then the result will be the solution for the given linear equation.

\begin{gathered}\end{gathered}

<u>Solution</u> :

\implies{\tt{9c  +  6 = 24}}

\implies{\tt{9c =  24 - 6}}

\implies{\tt{9c = 18}}

\implies{\tt{c = \dfrac{18}{9}}}

\implies{\tt{c  =  \cancel{\dfrac{18}{9}}}}

\implies{\tt{c  =  2}}

\star{\underline{\boxed{\tt{\red{c  =  2}}}}}

Hence, the value of c is 2.

A rectangles tabletop has a length of 4 3/4 feet and a area of 11 7/8 square feet what is the width of the tabletop
Natalija [7]
Area is length times width. Therefore, width is area divided by length. Convert 11 7/8 to the improper fraction 95/8 and convert 4 3/4 to 19/4. Then, you can fine 95/8 divided by 19/4 by flipping the second fraction and multiplying so that you have 95/8 times 4/19. 4 times 95 is 380 and 8 times 19 is 152. Therefore, the answer is 380/152. This is equivalent to 5/2 or 2.5.

I’m confused?????????
QveST [7]

Answer:

The equation of the line is y - 3 = 2.5(x - 2) ⇒ D

Step-by-step explanation:

The rule of the slope of a line is m = \frac{y2-y1}{x2-x1} , where

  • (x1, y1) and (x2, y2) are two points on the line

The point-slope form of a line is y - y1 = m(x - x1), where

  • (x1, y1) is a point on the line

From the given figure

∵ The line passes through points (2, 3) and (0, -2)

∴ x1 = 2 and y1 = 3

∴ x2 = 0 and y2 = -2

→ Substitute them in the rule of the slope to find it

∵ m = \frac{-2-3}{0-2}=\frac{-5}{-2}=2.5

∴ m = 2.5

→ Substitute the values of m, x1, y1 in the form of the equation above

∵ m = 2.5, x1 = 2, y1 = 3

∵ y - 3 = 2.5(x - 2)

∴ The equation of the line is y - 3 = 2.5(x - 2)
