Simplify. ‒36 ÷ (27 ÷ 3 ∙ 2)
andrew11 [14]

The simplified value  of expression -36/(27/3*2) is -8.

Given an expression -36/(27/3*2).

We are required to find the simplified value of given expression. To simplify the expression we need to use addition,subtraction,multiplication, division, brackets, etc. We can say that we have to use BODMAS in order to find the simplified value of expression.

Expression is combination of numbers, symbols, coefficients, determinants, indeterminants, fraction,algebraic operations,etc.  usually not found in equal to form.

The given expression :

=-36/(27/3*2)     (Multiplying 3 and 2 first)

=-36/(27/6)

=(-36*2)/9   (Invert the fraction given in denominator)

=-72/9          (Multiplying -36 to 2)

=-8

Hence the simplified value of expression -36/(27/3*2) is -8.

Joseph has a collection of stickers. When the stickers are aranged in piles of 3, there are 2 stickers left over. When the stick
Elodia [21]

Answer:

2 stickers will be left over

Step-by-step explanation:

To answer the question, all you need to do is figure out at what value of stickers would the remaining stickers be equal to 2 if the piles are made up of either 3 to a set or 4 to a set. To do this, we need to figure out the size of the whole set of stickers.

Lets assume that the total number of stickers is 14. Lets test the 2 given conditions. If we divide it in piles of 3 then we will have a pile of 12 stickers (4 piles of 3 stickers each) with 2 stickers remaining.

Lets test the second condition. If we divide it in piles of 4, we will again have 12 stickers (3 piles of 4 stickers each) with 2 stickers remaining.

Now that both conditions have been satisfied, all we have to do is see how many stickers are left if we make a pile of 12 stickers. In this case, we will have just one pile of 12 stickers and, again, we will be left with 2 stickers.

Therefore, the answer is 2 stickers

What do you notice about each solution? : 
Picture 1 - They never intersect/touch.
Picture 2 - They are intersecting.
Picture 3 - They are on top of each other.

What do you notice about the graphs for each set of equations? : 
Picture 1 - The lines are parallel.
Picture 2 - They are intersecting.
Picture 3 - They are on top of each other. (otherwise known as coincident lines).

What do you notice about each set of equations? : 
Picture 1 - They have the same slope but different y-intercepts.
Picture 2 - Both the slopes and y-intercepts are different for each equation.
Picture 3 - They have the same slope and same y-intercept.

What generalization can you make? : 
Picture 1 - When equations have the same slope but different y-intercepts they will be parallel when graphed.
Picture 2 - When the equations have different slopes and different y-intercepts they will be intersecting.
Picture 3 - When the equations are the same they will be coincident lines when graphed.

For each pair of points, find the slope of the line that passes through both points.
Georgia [21]

Step-by-step explanation:

a. (1,1) and (7,5)

b. (1,1) and (5,7)

c. (2,5) and (-1, 2)

d. (2,5) and (-7,-4)

Slope of the line that passes through the points

  The slope = \frac{y_{2} - y_{1}  }{x_{2} - x_{1}  }

a. (1,1) and (7,5) ;

    slope  = \frac{5-1}{7-1}   = \frac{4}{6}

     slope = \frac{2}{3}

b. (1,1) and (5,7)

      slope  = \frac{7-1}{5-1}  = \frac{6}{4}

      slope = \frac{3}{2}

c. (2,5) and (-1, 2)

      slope = \frac{2-5}{-1 - 2}  = \frac{-3}{-3}

       slope  = 1

d. (2,5) and (-7,-4)

      slope  = \frac{-4 - 5}{-7 - 2}  

       slope = \frac{-9}{-9}  = 1
