Answer:
The answer to your question is: 32 x + 2y - 107
Step-by-step explanation:
Simplify 5+2{y-4[3x+7(2-x)]}
5 + 2 { y - 4[ 3x + 14 - 7x ]}
5 + 2 { y - 12x -56 +28x }
5 + 2y - 24 x - 112 + 56x like terms
32 x + 2y - 107
Isolate the z. Note the equal sign. Subtract 1/7z to both sides
1/7z (-1/7z) + 2 = -6/7z (-1/7z)
2 = -6/7z - 1/7z
Simplify. Combine like terms
2 = -7/7z
2 = -1z
Isolate the z. Divide -1 from both sides
(2)/-1 = (-1z)/-1
z = 2/-1
z = -2
-2 is your answer

Answer: 639
Step-by-step explanation:
Answer: 24 points
Work Shown:
k = amount of points Katrina scored
k = 8
s = amount of points Sarah scored
s = 3k, since she scored three times as many
s = 3*8
s = 24 points
