Answer:
a = 5 and b= 1
Step-by-step explanation:
Line k: y = ax + b is parallel to l: y = 5x +3. same slope : 5 so : a = 5
Line k passes through point P(1,6). when x = 1 y = 6
6 = 5(1) +b
b= 1
Answer:
The actual mass of the book is between 481 . 5 g and 418 . 5 g.
Step-by-step explanation:
The mass of the book on the scale = 450 g
The percentage error in the scale = 7%
So, the actual mass of the book is 450 g ± 7%
Now, 7 % of the mass 450 g =
⇒ 7% of 450 g = 31.5 g
Now, the Actual mass of the book = 450 g ± 31.5 g
450 g + 31.5 g = 481 . 5 g
450 g - 31.5 g = 418 . 5 g
Hence the actual mass of the book is between 481 . 5 g and 418 . 5 g.

Answer:
600
Step-by-step explanation:
30 = 2 x <u>3</u> x 5
40 =<u>2 x 2 x 2</u> x 5
75 = <u>5 x 5</u> x 3
L.C.M =<u> 2 x 2 x 2</u> x <u>5 x 5 </u>x <u><em>3 </em></u>
=600
