Antonio ran 129 laps at the park. Alan ran 20% more than that. how many laps did Alan run

Answers

Answer:

154.8

Step-by-step explanation:

20% is equal to 20/100= 0.20. So, 0.20 multiplied by 129 will give you 20% of 129 which is 25.8. If Alan ran 20% more then you add 25.8 to 129 which gives you an answer of 154.8.

Equation: 20/100= 0.2

                0.2* 129= 25.8

                25.8+129= 154.8

Alan ran 154.8 laps.

Evaluate the expression when y= 7 and x = 9.
x + 4y

Answers

Answer:

  [1]    9x - 4y = 7

  [2]    x - 4y = -17

 [2]    x = 4y - 17

// Plug this in for variable  x  in equation [1]

  [1]    9•(4y-17) - 4y = 7

  [1]    32y = 160

// Solve equation [1] for the variable  y  

  [1]    32y = 160

  [1]    y = 5

// By now we know this much :

   x = 4y-17

   y = 5

// Use the  y  value to solve for  x
