earns 2 points for each correct answer
loses 0.5 points for each incorrect answer
13 correct answers
2 incorrect answers
13 (2)-2(0.5) = 26-1 = 25
Score = 25 points
A and B are equivalent and C and D are equivalent
To find k, divide both sides by 1/4
K = 2/3 / 1/4
When dividing by a fraction flip the second fraction over then multiply:
K = 2/3 x 4/1 = (2 x 4) / (3 x 1) = 8/3
K = 8/3 = 2 and 2/3
If it is 63 in across, and each part is equal, the equation so solve this is: 63=3x
So, you take 63=3x and divide each side by 3
63/3=3x/3
Then simplify
21=x
This means each panel is 21 inches wide.
