PLS HELP 75 POINTSSSSSSSSS WILL MARK BRAINLIEST!!!!!!

Mathematics
1 answer:
Julli [10]3 years ago
4 0

Answer:

Step-by-step explanation:

3x - 4y = 9...........(1)

2x + 8y = 6..........(2)

Multiply (1) by 2 and (2) by 3

6x - 8y = 18.........(3)

6x + 24y = 18......(4)

Subtracting (3) from (4)

24y - (-8y) = 18 - 18

24y + 8y = 0

32y = 0

y = 0/32

y = 0

Substituting y = 0 into (1)

3y - 4y = 9

3y - 4(0) = 9

3y = 9

y = 9/3

y = 3

Hi,

\sqrt{163} = 12.76

There are no other simple steps to reduce the square root of one hundred and sixty-three.

The actual square root value is ≈12.767145334803704

But we have taken only significant figures and it is as 12.76.


Hope it helps! :)

The larger of two numbers is four times the smaller number, and their difference is 18. Find the two numbers.
podryga [215]

Answer:

x = 12 , y = 10

Step-by-step explanation:

Let x , y are two numbers.

x > y

1 ) Three times the greater is 18 times their

difference

3x = 18( x - y )

x = 6( x - y )

x = 6x - 6y

6y = 5x

y = 5x/6 ——-( 1 )

2 ) 4 times the smaller is 4 less than twice

the sum of the two

4y + 4 = 2 ( x + y )

2y + 2 = x + y

y = x -2 ——( 2 )

From ( 1 ) and ( 2 ) ,

5x/6 = x -2

( 5x /6 ) - x = -2

( 5x - 6x ) /6 = -2

-x = -12

x = 12

Put x = 12 in equation ( 2 ) , we get

y = 12 - 2

y = 10

Therefore ,

x = 12 , y = 10
