Answer:
yes it is!!
Step-by-step explanation:
8 - 4(x - y) = 2x + 6
8 - 4x + 4y = 2x + 6
-4x - 2x + 4y = 6 - 8
-6x + 4y = -2
6x - 4y = 2 <====
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
