Let the total number of rugs be x
To find the total number of rugs we must first find the total parts which is
3 + 4 = 7
4/7 of the total rugs are 84 Oriental rugs
Which is written as

Answer:
C
Step-by-step explanation:
Use Pythagorean theorem
X^2 + 44^2 = 55^2
X^2 = 55^2 - 44^2
= 3025 - 1936
X^2 = 1089
X = sqrt (1089)
X = 33
Answer: False. 21 Shelves.
Step-by-step explanation:
First, 12 x 31= 372
This indicates that there are 372 books.
Then, 372 ÷ 18= 20.6666666667
Since we have a decimal that is above 4 we round up.
This leaves 21 shelves needed for all the books o fit on a shelf.
Answer:
(6, - 9 )
Step-by-step explanation:
Given the 2 equations
6x + 2y = 18 → (1)
- 4x - 2y = - 6 → (2)
Adding the 2 equations term by term will eliminate the y- term, that is
2x + 0 = 12
2x = 12 ( divide both sides by 2 )
x = 6
Substitute x = 6 into either of the 2 equationsand solve for y
Substituting into (1)
6(6) + 2y = 18
36 + 2y = 18 ( subtract 36 from both sides )
2y = - 18 ( divide both sides by 2 )
y = - 9
solution is (6, - 9 )
