Couch: 2x
love seat: 2x+400
chair: x
total amount: $1565
2x+2x+400+x=1565
5x+400=1565
5x=1165
x= 233
The cost of the chair is $233. The cost of the couch is $466. The cost of the love seat is $866.
Hope this helps!

Answer:
The interior angle measure of a convex decagon is 144.
Step-by-step explanation:
The sum of the interior angle formula for a convex polygon is (n-2)180
where n is the number of sides.
A decagon has 10 sides.
10-2 = 8
8 times 180 = 1440
A decagon has 10 sides-10 angles.
To find the measure of each angle divide by 10.
1440/10=144
The interior angle measure of a convex decagon is 144.
Answer:
x = 5
Step-by-step explanation:
= 19 - x = 14
= 19 - x - 19 = 14 - 19
= -x = -5
= -x/-1 = -5/-1x
x = 5
