Answer:
length = 18 mt
Width = 10 mt
Step-by-step explanation:
Let the length of the field be x
width of the field be y
Hence
P=2(x+y)
P=56 (given)
56=2(x+y)
Dividing both sides by 2 we get
x+y=28 ---(A)
Also given that width of the parallelogram is 8 meters less than its length
Hence
y=x-8
or x-y=8 ---(B)
Adding A and B
2x=36
x=18
y=x-8
y=18-8=10
Hence length = 18 mt
Width = 10 mt
Answer: D
Step-by-step explanation:
It is a linear function and the slope is negative and the y intercept is negative.
Answer:
Rs 8500
Step-by-step explanation:
For a cost price of c, the marked price is ...
marked = c +25%·c = 1.25c
After the 15% discount, the sale price will be ...
s = marked -15%·marked = 0.85·marked = (0.85)(1.25c) = 1.0625c
The profit will be the difference between the sale price s and the cost c:
p = s -c
500 = (1.0625c) -c = 0.0625c
Then the cost is ...
500/0.0625 = c = 8000
and the sale price is ...
s = c +p = 8000 +500 = 8500 . . . rupees
The selling price will be Rs 8500.
2x+38=50
2x+38-38=50 -38
2x =12
2x/2 =12/2
x=6
No, because the equation shows her answer. 30 and 2 combined equals 32, which is the answer. 32x4=128 and 128/4=32
