There are a few ways to solve this. The method I will use is the substitution method. Since they give us a "y = " statement, we can replace the y in the second equation with what it gives us to the right of the equal sign.
- 3x + 6(- 2x - 1) = 24
Simplify by using the distributive property.
- 3x + 6(- 2x) + 6(- 1) = 24
- 3x - 12x - 6 = 24.
Combine like terms
- 15x - 6 = 24
Add 6 to each side.
- 15x = 30
Divide both sides by - 15 to isolate variable X
x = 30 / - 15
x = - 2.
Now plug in the x-value we've found back into the first equation.
y = - 2( - 2) - 1
y = 4 - 1
y = 3
Your answer is (- 2, 3)
Multiply 9.6 pounds of trail mix by $1.20.
9.6 * 1.20 = 11.52
Corrine will spend $11.52 on trail mix.

Answer:
3m²
Step-by-step explanation:
A square is quadrilateral (four sides) in which all sides are equal. Also, opposite sides are parallel to one another and all the four angles in a square are 90 degrees each.
The area of a square is given as:
Area = length * length
Given that the square has side lengths of m centimeters, therefore:
The area of each square = m cm × m cm = m² cm²
There are three rows of m squares, hence the total number of square is:
Total square = 3 rows * m squares per row = 3m squares
The total area of the square = area of each square * total number of square = m² * 3m = 3m² cm²
