The skate Sports Store offers 4-wheel and 5-wheel inline skates. On display in the store are the left skates for 17 different st
beks73 [17]

There are 6 skates in store with 5 wheels.

<h3>What is Equation?</h3>

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign.

Here, Let the number of 4 wheel skates in display be x

         and the number of 5 wheel skates in display be y

       Total number of skates = 17

       Total number of wheel = 74

Now, according to question

        x + y = 17     ................(i)

        4x + 5y = 74 ..................(ii)

From equation (i), we get

          x = 17 - y   ................(iii)

put the value of y in equation (ii), we get

      4(17 - y) + 5y = 74

       68 - 4y + 5y = 74

          y + 68 = 74

          y = 6

Put the value of y in equation (iii), we get

          x = 17 - 6

          x = 11

Thus, there are 6 skates in store with 5 wheels.

sports warehouse had a sale on two models of baseball gloves. Model A sold for $30.00, and model B sold for $45.25. A total of 5
alexandr402 [8]

Answer:

18 model A gloves and 34 model B gloves

Step-by-step explanation:

Set up 2 equations based on the given information

Let 'x' represent the number of Model A gloves sold

Let 'y' represent the number of Model B gloves sold

Then..

$30x + $45.25y = $2,078.50  represents the total sold in dollars

    x    +     y       =    52  represents the total number of gloves sold

Solve the second equation for either variable...

   x = 52 - y            

Now plug this into the first equation...

$30(52 - y) + $45.25y = $2,078.50            {x became 52 - y}

Now solve for y...

$1,560 - $30y + $45.25y = $2,078.50

     $15.25y = $518.50   (combine y terms, subtract $1,560 from both sides)

            y =  34             (divide both sided by $15.25, dollar signs cancel out)

PLS HELP <br> solve the system of equation using elimination:<br> 3x+y=-2<br> 5x-y=-10
vredina [299]

Answer:

(-3/2, 5/2)

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Algebra I</u>

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define systems</u>

3x + y = -2

5x - y = -10

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Eliminate y</em>

  1. Add 2 equations together:                     8x = -12
  2. Divide 8 on both sides:                           x = -12/8
  3. Simplify fraction:                                      x = -3/2

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Define original equation:                    3x + y = -2
  2. Substitute in <em>x</em>:                                     3(-3/2) + y = -2
  3. Multiply:                                                -9/2 + y = -2
  4. Add 9/2 on both sides:                        y = 5/2
