Step-by-step explanation:
Given,
Height of ceiling in bedroom = 10 feet
This is 2/3 height of living room ceiling.
Let,
x be the height of living room ceiling.
2/3 of x = 10
Multiplying both sides by 3
Dividing both sides by 2
The height of living room ceiling is 15 feet.

Answer:the clothing store paid $97.6 for the jeans
Step-by-step explanation:
Let x represent the price at which the clothing store bought the jeans from the manufacturer or the amount paid to the manufacturer.
The local clothing store marks up the price that it pays to the clothing manufacturer by 25%. This means that the selling price for a pair of jeans would be
(25/100 × x ) + x = 0.25x + x = 1.25x
If the selling price of a pair of jeans is $122, it means that
1.25x = 122
x = 122/1.25 = $97.6
Answer:
the perimeter is 10.5 and the area is 33.75
Step-by-step explanation:
Answer:
∠ 2 = 70°
Step-by-step explanation:
∠ 13 and ∠ 14 are adjacent angles and sum to 180° , then
12x - 22 + 9x - 29 = 180
21x - 51 = 180 ( add 51 to both sides )
21x = 231 ( divide both sides by 21 )
x = 11
Then
∠ 14 = 9x - 29 = 9(11) - 29 = 99 - 29 = 70°
∠ 7 = ∠ 14 = 70° ( Alternate angles )
∠ 2 = ∠ 7 = 70° ( Alternate angles )
