The answer is 100 cm.
250 cm - 1 1/2 m = ?
1 1/2 m = 1 + 1/2 = 2/2 + 1/2 = (2 + 1)/2 = 3/2 = (3*5)/(2*5) = 15/10 = 1.5 m
1 m = 100 cm
1.5 m = 150 cm
250 cm - 1 1/2 m = = 250 cm - 150 cm = 100 m

a
Step-by-step explanation:
Calculate the area of the room and then subtract the area of the tiled floor.
area of room = 11 3/4 x 5 = 58 3/4
Area of tiled floor = 7 1/2 x 3 1/4 = 24 3/8
area of carpet = 58 3/4 - 24 3/8 = 34 3/8
answer: 34 3/8
Answer:

Step-by-step explanation:


Since
, then

<span>x + 3y= -11 (1)
</span><span>-9y = 33 + 3x ---->3x + 9y = -33 (2)
divide (2) equation by 2
</span>3x + 9y = -33
x + 3y = -11 (2')
and equation (1) is also x + 3y= -11 (1)
so
x + 3y= -11 (1)
x + 3y= -11 (2')
