Answer:

Step-by-step explanation:

Given that

x^2 ≡ 53 (mod 77)

Right side has values as

53, 53+77, 53+2(77),+....

We have to find one which is a perfect square.

We have from this series 361 is 19 square

Thus x =19.

Next is x^2=900\\x=30

x^2=2209\\x=47 and so on.

The values of w is inversely proportional to m .if w=8 then m=25; what is m when w=20?
iren2701 [21]

Answer:

m = 10

Step-by-step explanation:

Given w is inversely proportional to m then the equation relating them is

w = \frac{k}{m} ← k is the constant of variation

To find k use the condition w = 8, m = 25 , then

8 = \frac{k}{25} ( multiply both sides by 25 )

200 = k

w = \frac{200}{m} ← equation of variation

When w = 20 , then

20 = \frac{200}{m} ( multiply both sides by m )

20m = 200 ( divide both sides by 20 )

m = 10
