Respuesta :

156. Because 20% of 130 is 26 so 130+26=156.

The number of the swimmers are boys is 195. Then the number of the total swimmer will be 325.

What is the linear system?

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Let x be the number of boys and y be the total swimmer.

On a local swim team, 60% of the swimmers are boys. Then the equation will be

60% of y = x

    0.60y = x     ...1

If 130 of the swimmers are girls. Then the equation will be

x + 130 = y     ...2

From equation 1 and 2, then the equation will be

0.60y + 130 = y

   y - 0.60y = 130

        0.40y = 130

                y = 325

Then substitute the value of y in equation 2, then the value of x will be

x + 130 = 325

         x = 325 - 130

         x = 195

Thus, the number of the swimmers are boys is 195. Then the number of the total swimmer will be 325.
