Simplifying

7x + -4y = 23


Solving

7x + -4y = 23


Solving for variable 'x'.


Move all terms containing x to the left, all other terms to the right.


Add '4y' to each side of the equation.

7x + -4y + 4y = 23 + 4y


Combine like terms: -4y + 4y = 0

7x + 0 = 23 + 4y

7x = 23 + 4y


Divide each side by '7'.

x = 3.285714286 + 0.5714285714y


Simplifying

x = 3.285714286 + 0.5714285714y

If a dart was thrown randomly at the dart board shown below, what is the probability that it would land between the outer circle
Mademuasel [1]

Answer:  B) 67%

<u>Step-by-step explanation:</u>

Find the Area of the Bullseye and Middle ring

A = π r²

A (inside) = π(8)² = 64π

Find the Area of the entire Target

A (target) = π (14)² = 196π

Find the Area of the Outer ring

A (outer ring) = A (target) - A(inside)

                      =   196 π    -    64π

                      =    132 π

The last step is to find the probability of landing on the outer ring:

P=\dfrac{success (area\ of\ outer\ ring)}{total\ possible\ outcomes(area\ of\ target)}=\dfrac{132\pi}{196\pi}=0.673=\large\boxed{67\%}
