(1) One number exceeds the other by 9 and theirsum is 49. (Take one number as x)

Answer»

Answer:

x=20

Step-by-step EXPLANATION:

let the number be x

so other number be x+9

their SUM = 49

so,

x+x+9 = 49

2x +9 = 49

2x = 40

x = 40/2

x = 20

so other number will be

x+9 = 20+9

= 29

so two numbers are

20 & 29

Verify that (x+y)-1x-1+y-1 by taking x=4/9and y=-3/5.

Answer»

ANSWER:

firstly SOLVE (x+y) - 1

put the value

{(5/9)+(-4/3)} - 1

(5/9-4/3)-1

LCM=9

(5/9-12/9)-1

-7/9-1=-7/9-9/9=-16/9

then solve x-1 + y-1

(5/9-1)+(-4/3-1)

(5/9-9/9)+(-4/3-3/3)

(-4/9)+(-7/3)

-4/9-21/9

-17/9

-16/9 is not equal to -17/9

Hence proved

Answer»

Answer:

let the side AC be HYPOTENUSE of trinagle ∆ ABC

let the side BC be base of TRIANGLE of ∆ ABC

GIVEN : side AC = 17 and side BC = 10.5

Applying Pythagoras theorem

Hyp² = base² + height²

(17)² = (10.5)² + (HEIGHT)²

289 = 110.25 + height²

height² = 289 - 110.25

= 178.75

taking √ both side

height² = √178.75

height = 13.36

I think this is the answer. if it is not perfect for you then can report me.
