We have a dilemma here, there is a variable and constant numbers in this equation. No fear, this is when like terms comes into play, where you can only combine two numbers that have the same ending, whether it be variables, exponents, e.t.c.

Distribute :

4 + 16 - 12(1 + 2x)

4 + 16 - (12(1) + 12(2x))

4 + 16 - 12 + 24x

Use PEMDAS (Add left to right) :

4 + 16 - 12 + 24x

20 - 12 + 24x

8 + 24x

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  

   x = 4(5)-17 = 3

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.
