Answer:

Step-by-step explanation:

You need to set up a proportion

Let x = NK

7/13 = x/56    Notice that the longest side of the small trapezoid is the denominator of the fraction  on the left. That means that the longest side of the large trapezoid must also be the denominator of that fraction on the right.

Cross multiply

13x = 7*56                Combine the right

13x = 392                 Divide by 13

x = 392/13

x = 30.15

NK = 30.15

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.
