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

Answer:
$7.20
Step-by-step explanation:
We'll need to find out 40% of 12 then subtract that amount because we're still paying 60% of the original price.
Change the percent to a decimal: 0.4
Multiply the sale price and the decimal
12 · 0.4 = 4.8
Subtract 40% of the price from 12
12 - 4.8 = 7.2
