Answer:
18 seconds
Step-by-step explanation:
8:10 = 4:5, 4+5 = 9, 9 x 2 = 18 seconds :D
30,000+9,000+700+1 is the expanded form
Here is your answer
Since the door will be in shape of a rectangle where,
length= 80 inches
breadth= 72 inches
So,
widht of largest mattress that can fit diagonally is diagonal of the door.
i.e.
HOPE IT IS USEFUL
Y=2x-4
X+2y=10
Put y into the x equation
X+2(2x-4) =10
Expand and simplify
X+4x-8=10
5x-8 =10
5x=10+8
5x=18
X=18/5
Insert x into the original equation to get y
Y=2x-4
Y=2(18/5)-4
Y=16/5
Are you sure its Y? Maybe you mean to put 0
