Answer:
Width = 160
Length = 110
Step-by-step explanation:
Perimeter is the sum of all the sides
They tell you that the length is 50 m shorter than the width
so L = W - 50
W = W
540 = W + W + W-50 + W-50
540 = 2W + 2(W-50)
540 = 2W + 2W - 100
540 = 4W - 100
640 = 4W
W = 160
L = 160 - 50
L = 110
Answer:
<em>Each of you should chip in </em><em>$5.4</em>
Step-by-step explanation:
You are going on a road trip over a distance of 300 km with three friends.
The car consumes 6 liters of gas per 100 km and gas costs $1.20 per liter.
For 100 km the car consumes 6 liter of fuel, so for 300 km it will consume
For 1 liter of gas it costs $1.20, so for 18 liters it will cost
As total 4 persons are there, so each will contribute
3 - 6 - 9 - 12 - 15 - 18 - 21 - 24 - 27 - 30 - 33 - 36 - 39 - 42 - 45 - 48 - 51 - 54 - 57 - 60
4 - 8 - 12 - 16 - 20 - 24 - 28 - 32 - 36 - 40 - 44 - 48 - 52 - 56 - 60
5 - 10 - 15 - 20 - 25 - 30 - 35 - 40 - 45 - 50 - 55 - 60
SOOOO that means the LCD is 60 c:
( Basically, to find the LCD all you gotta do is count by whichever number is the denominator until they match, in this case, it was 60 )
You can do the rest :D
