The keyword is "sum" which tells you x, y, and z are being added. One half of the sum means that the sum of the three numbers is going to be divided by 2.
x + y + z

x = # of games playing.
4.75x + 3 = 42
4.75x = 39
x = 39 /4.75
x = 8.21
Answer:
Shakira played about 8 games
Answer:
3.38
Step-by-step explanation:
x + y + z = 16.9
x = 2y
y = z
y=y
2y (x) + y(y) + y(z) = 16.0
5y = 16.9
y = 3.38
X= 4y+4/3yz this is they solution
Answer: The slope is 4x.
Step-by-step explanation: First, subtract 4y from both sides to get 16x-4y=1. Next, subtract 16x from both sides to get -4y=-16x+1. Finally, divide all terms by -4 to get y=4x-0.25. The slope is represented by 4x.
