Abaseball team played 154 regular season games. the ratio of the number of games they won to the number of games they lost was 5/2. how many games did they lose? also, the lengths of the sides of a triangle are in the extended ratio 6: 7: 9. the perimiter of the triangle is 88cm. what are the lengths of the sides? ireally need since i wasn't in class to go over this.

A.
Let
5x = number of games won
2x = number of games lost
The total number of win and lose is 154. So
5x + 2x = 154
Solving for x,
7x = 154
x = 22

Therefore, the number of games won is 5*22=110 and the number of games lost is 2*22 is 44.

b.
Let
6x = first side of the triangle
7x = second side of the triangle
9x = third side of the triangle
The perimeter of a triangle is the total of all sides. So,
6x + 7x + 9x = 88
22x = 88
x = 4
Therefore, the three lengths of the side are 6*4=24, 7*4=28, and 9*4 = 36

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
