Question

A baseball 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 help since I wasn't in class to go over this.

Answer 1

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
