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

SOMEONE HELP ME PLEASE

Answer:

<h3>Angle 6 = 101°</h3><h3>Angle 5 = 79°</h3><h3>Angle 7 = 79</h3>

Step-by-step explanation:

Angle 6 will 101°

This is because we can see that Angle 4 is alternate interior angle to Angle 6 and alternate interior angles are always equal.

<h2>So angle 6 will be 101°</h2>

Angle 7 = 79°

Here we can see that Angle 6 and angle 7 are supplementary which means it has a measure of 180°

So the value of Angle 7 will be

$180 - 101 = 79$

<h2>Hence the measure of angle 7 will be 79°</h2>

Angle 5 = 79°

Angle 7 and Angle 5 is vertically opposite to each other and we know that vertically opposite angles are always equal so the measure will be 79°

<h3>Hence the measure of Angle 5 will be 79°</h3>
