Answer:
$720
$360
Step-by-step explanation:
Let the cost of couch be A and that of coffee table be B
Given couch and coffee table cost $1080
That’s
A + B = $1080
Also, the cost of couch A is 2 times the cost of coffeee table B.
That’s
A = 2B
We now have two equations
A + B = 1080
A = 2B
Now ,substitute 2B for A in the first equation .
We have
A + B = 1080
2B + B = 1080
3B = 1080
Divide both sides by 3
3B/3 = 1080/3
B = 360
The coffee table cost $360
Remember A = 2B
Therefore
A = 2 x $360
A = $720
The couch cost $720 while the coffee table cost $360
Answer:
Therefore, the variable expression when a=-4, b=2, c=-3, and d =4 is
![\dfrac{b-3a}{bc^{2}-d}=1](https://tex.z-dn.net/?f=%5Cdfrac%7Bb-3a%7D%7Bbc%5E%7B2%7D-d%7D%3D1)
Step-by-step explanation:
Evaluate:
![\dfrac{b-3a}{bc^{2}-d}](https://tex.z-dn.net/?f=%5Cdfrac%7Bb-3a%7D%7Bbc%5E%7B2%7D-d%7D)
When a=-4, b=2, c=-3, and d =4
Solution:
Substitute, a=-4, b=2, c=-3, and d =4 in above expression we get
![\dfrac{b-3a}{bc^{2}-d}=\dfrac{2-3(-4)}{2(-3)^{2}-4}\\\\=\dfrac{2+12}{18-4}\\\\](https://tex.z-dn.net/?f=%5Cdfrac%7Bb-3a%7D%7Bbc%5E%7B2%7D-d%7D%3D%5Cdfrac%7B2-3%28-4%29%7D%7B2%28-3%29%5E%7B2%7D-4%7D%5C%5C%5C%5C%3D%5Cdfrac%7B2%2B12%7D%7B18-4%7D%5C%5C%5C%5C)
![\dfrac{b-3a}{bc^{2}-d}=\dfrac{14}{14}=1](https://tex.z-dn.net/?f=%5Cdfrac%7Bb-3a%7D%7Bbc%5E%7B2%7D-d%7D%3D%5Cdfrac%7B14%7D%7B14%7D%3D1)
Therefore, the variable expression when a=-4, b=2, c=-3, and d =4 is
![\dfrac{b-3a}{bc^{2}-d}=1](https://tex.z-dn.net/?f=%5Cdfrac%7Bb-3a%7D%7Bbc%5E%7B2%7D-d%7D%3D1)
