Answer:

Step-by-step explanation:

2y + 100 +6x-10=180(in a cyclic quadrilateral opposite angles are supplementary)

2y+6x+90 =180

2y + 6x = 90

dividing each side by 2

y+3x = 45 ........1

7x+1+2y+74 =180 ( same reason)

7x + 2y =105 ............2

multiplying 1 by 2

2y +6x =90........ 3

subtracting 3 from 2

7x+2y-2y-6x = 105-90

x = 15

substituting x=15 in 1

y+45 =45

y= 0

please mark me as the brainliest

After 50 soccer games, the ratio of wins to losses is 3:7. How many games did the team win? Explain how you found your answer

zalisa [80]

Answer:The team won 15 games

Step-by-step explanation:

Given no of soccer games =50

Ratio of wins to losses =3:7

Let no of wins = $3x$

and no of losses = $7x$

Now

$3x+7x=50$

$10x=50$

Dividing both sides by 10

x=5

So no of wins =3x = $3\times5$

=15

We found the answer as 10 parts equals 50

So 3 parts equals 15
