We let x as the cost of one night’s hotel accommodations and y as the cost of one pair of baseball tickets. For plan A, we can generate the equation as 3x + 2y = $557 and for plan B; 6x + 4y = $1114

Using elimination, we can write the two as:

3x + 2y = 557

5x + 4y = 974

Multiply both eq. 1 by 2 to eliminate y

2(3x + 2y = 557)2

6x + 4y = 1114

We now have

6x + 4y = 1114

5x + 4y = 974        ⇒ subtract

X = 140

Substitute x to either equation to get the value of y

3(140) + 2y = 557

2y = 557 – 420

2y = 137

Y = 68.5

What is the denominator of the simplified expression?(2n/6n+4)(3n+2/3n-2)
Sedbober [7]

Answer:

The denominator of the simplified expression is 3 n - 2

Step-by-step explanation:

Given expression as :

(\dfrac{\textrm 2n}{\textrm 6n+4} ) × (\dfrac{\textrm 3 n + 2}{\textrm 3 n - 2} )

or, \dfrac{\textrm 6n^{2}+4n }{\textrm 18n^{2}-12 n +12 n -8 }

Or, \dfrac{\textrm 6n^{2} + 4n }{18n^{2}-8 }

or,  \dfrac{\textrm 3n^{2} + 2n }{9n^{2}-4 }

Or, \dfrac{3n^{2}+2n }{(3n+2)(3n-2)}

Or,  \dfrac{n (3n + 2) }{(3n+2)(3n-2)}

∴ \dfrac{n}{3 n - 2}

Hence The denominator of the simplified expression is 3 n - 2  Answer
