Answer: (0,-2)
Step-by-step explanation:
3x - 4y = 8
18x -5y = 10
-6(3x -4y)=8(-6)
-18x + 24y = -48
18x -5y = 10
19y= -38
y= -2
18x - 5(-2) =10
18x + 10 = 10
10 10
18x= 0
x= 0
Given that
The width of a bookshelf must be no greater than 6 1/2 feet.
And a bookshelf that is 77 inches wide.
Since i ft = 12 inches
So 6.5 feet = 6.5×12 = 78 inches
So 78 inches > 77 inches
So the difference is 1 inch.
There are several information's already given in the question. based on those information's, the answer can be easily determined.
Height of the box = h cm
Length of the box = 10 cm
Width of the box = 2h
Then
Volume of the box = Length * height * width
= 10 * h * 2h cubic cm
= 20h^2 cm^3
I hope that the above procedure is clear enough for you to understand and it has actually come to your desired help.
1. 2(3-4)+6= 2(-1)+6= -2+6= 4
2. (26-5):3+1= (21):3+1= 7+1= 8
