X songs
Y games
A) 8X + 3Y = 20.50
B) 4X + 5Y = 22.50
Multiplying equation B) by -2
B) -8X -10Y = -45.00 then adding this to
A) 8X + 3Y = 20.50 we get
-7Y = -24.50
Y = 3.50
I think you can calculate X right?
Answer:
Step-by-step explanation:
First, make A equal one by factoring out the greatest common factor, 6. This makes the new expression . Then, factor the remaining polynomial by finding two numbers that multiply to -90 and add to 1. These two numbers are -10 and 9. So, add each term to x and then multiply to get the final answer, .

Answer:
k = 2/15
Step-by-step explanation:
We can solve the given equation for k:
k = s/p . . . . . . divide the given equation by p on both sides
Using the first values from the table (15 pounds, 2 scoops), we have ...
k = 2/15
The value of k is 2/15.
Answer:
Heun's method is also known by its other name called Modified Euler methods. This method is used in computational or mathematical science.
Step-by-step explanation:
Euler method is the method that is also pronounced in two similar stages such as Runge- Kutta methods. This method has been named after Dr. Heun.
This method is used for the solution of ordinary differential equations with its given values. There is some method to calculate this method. The improved Runge Kutta methods are also called the Butcher tableau method, the other methods are also called the Ralston methods.

Step-by-step explanation:
(x+2)(3x-3)
= 3x^2 -3x + 6x - 6
= 3x^2 + 3x - 6
