Answer:

Step-by-step explanation:

Let x represent the amount that Lisa paid for the pizza.

Steven said he could pay twice as much as Lisa. This means that the amount that Stephen would pay would be

2 × x = 2x

Mark said he could pay the remaining $3 which is $1 less than Lisa's share. This means that the amount that Mark could pay would be

3 = x - 1

x = 3 + 1 = 4

amount that Stephen would pay would be

2x = 2 × 4 = 8

Total cost of the pizza is the sum of the amount paid by Stephen, Lisa and Mark. It becomes

4 + 8 + 3 = $15

At the bargain store , Tanya bought 3 items that each cost the same amount. Tony bought 5 items that each cost the same amount b
Afina-wow [57]

Answer:

"Tanya bought 3 items that each cost the same amt"

"Let x represent the cost of one of Tanya's items"

  So, Tanya bought 3 items, costing x+x+x = 3x

  Note that (number of items)*(cost per item) = (number of items)*(cost/item) = cost,   [item cancels out]

 

"Tony bought 4 items that each cost the same amt, but each was $2.25 less than the items Tanya bought."

 The cost for Tony's items was:  (x-2.25)+(x-2.25)+(x-2.25)+(x-2.25) = 4*(x-2.25)

 

"Tanya and Tony paid the same amt. of money"

   This is an equation (the same amount means equals)

    Tanya's cost = Tony's cost

a.) Write an equation. Let x represent the cost of one of Tanya's items

          3x      =     4(x-2.25)

 

Now, the math:

b.) Solve the equation. Show your work.

          3x      =     4(x-2.25)

          3x  =  4x - 9.00                 [distributive principle; multiply]

         -x = -9.00                      [subtract 4x from both sides; option, could instead add 9.00, then subtract 3x from both sides, getting 9.00=x]

          x = 9.00           [multiply both sides by (-1)]

                 [note:  to "solve for x" means to find the value(s) of x that make the equation true,

                          so let's see if it is true --]

c.) Check your solution. Show your work.

  Is              3x      =     4(x-2.25), when x=9.00    ?

          3(9.00) = 4(9.00-2.25)    ?

           27.00 = 36.00 - 9.00    ?

             27.00 = 27.00    ?yes

 

d) State the solution in a complete sentence.

     The problem started with:  "Tanya bought 3 items that each cost the same amt. Tony bought 4 items that each cost the same amt, but each was $2.25 less than the items Tanya bought. Both Tanya and Tony paid the same amt. of money."

     I would write:   "Tanya bought 3 items, each costing $9.00.  Tony bought 4 items, each costing $6.75.  Tanya and Tony each paid $27.00."

Since
 18x^3=2\cdot 3\cdot 3\cdot x\cdot x\cdot x \\  \\ 30x^5=2\cdot 3\cdot 5\cdot x\cdot x\cdot x\cdot x\cdot x
you can see that common expression is 
2\cdot 3\cdot x\cdot x\cdot x=6x^3.
