-5n=4m+8
4m+8=-5n
4m=-5n-8
m=-5n/4 - 8/4
m=-5n/4 - 2

Answer: the value of m for each value of n is:
m=-5n/4 - 2

if n=-1
m=-5(-1)/4 -2=5/4 - 2=(5-8)/4=-3/4

if n=0
m=-5(0)/4 -2=0-2=-2

fi n=1
m=-5(1)/4 - 2=-5/4 -2=(-5-8)/4=-13/4

Answer: if n=-1, then  m=-3/4;  if n=0, then m=-2, if n=1, then m=-13/4.

(b) How much the selling price should be fixed for pulse bought for Rs.70 per kg. to earn a profit of Rs.6 after allowing a 5 %
Mama L [17]

Answer:

Rs. 80

Step-by-step explanation:

Given that :

Purchase price = 70

Profit = 6

Discount = 5%

Let selling price = x

Selling price * (1 - discount) = (purchase price + profit)

x * (1 - 5%) = (70 + 6)

x * (1 - 0.05) = 76

x * 0.95 = 76

0.95x = 76

x = 76 / 0.95

x = 80

Hence, selling price = Rs. 80

The scale of a map is 1 : 25 000
Artyom0805 [142]

Answer: 5.5km

Step-by-step explanation:

The scale given 1 : 25 000 , and it was said that on the map , the distance between two railway stations is 22 cm , this means that the scale of the map is 1: 25000 cm.

The scale 1 : 25 000 means that each centimeters on the map represent 25 ,000 in real life ,therefore , to calculate the real distance between the two railway station , we have

25,000 X 22

= 550000 cm

To convert this to km

Recall that

1 km = 100,000 cm

Therefore we will divide the answer by 100,000 , that is

550000/100000

= 5.5 km

Therefore , the real distance between the two railway stations is 5.5km
