answer:
Simplifying Y2 + -20X + -6y + -51 = 0
Reorder the terms: -51 + -20X + Y2 + -6y = 0
Solving -51 + -20X + Y2 + -6y = 0
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '51' to each side of the equation. -51 + -20X + Y2 + 51 + -6y = 0 + 51
Reorder the terms: -51 + 51 + -20X + Y2 + -6y = 0 + 51 Combine like terms: -51 + 51 = 0 0 + -20X + Y2 + -6y = 0 + 51 -20X + Y2 + -6y = 0 + 51
Combine like terms: 0 + 51 = 51 -20X + Y2 + -6y = 51
Add '-1Y2' to each side of the equation. -20X + Y2 + -1Y2 + -6y = 51 + -1Y2
Combine like terms: Y2 + -1Y2 = 0 -20X + 0 + -6y = 51 + -1Y2 -20X + -6y = 51 + -1Y2 Add '6y' to each side of the equation. -20X + -6y + 6y = 51 + -1Y2 + 6y Combine like terms: -6y + 6y = 0 -20X + 0 = 51 + -1Y2 + 6y -20X = 51 + -1Y2 + 6y Divide each side by '-20'. X = -2.55 + 0.05Y2 + -0.3y Simplifying X = -2.55 + 0.05Y2 + -0.3y
Answer:
(-1)(-3)
Step-by-step explanation:
When two negatives are multiplied it always equals a positive making it the only one that equals positive 3.
Answer:
Solution not exists.
Step-by-step explanation:
Since in a certain step a certain amount divided by zero, an that stage the quentity is undefined. That is if,
Then, at the next stage, 
is not exists, wheather after it divided by 1 or not. Thus required solution is not exists.
Answer:
6 questions
Step-by-step explanation:
<u>First</u>, you divide the total score of 100 by the 64 questions to get 1.5625 points per question. <u>Next</u>, you divide the lowest score to qualify of 90 by the 1.5625 to get 57.6 questions correct to qualify. <u>Then</u>, you round 57.6 questions correct up to 58 questions correct because a fraction of a question correct doesn't make sense. <u>Finally</u>, you subtract the total number of questions (64) by the required correct answers (58) to get 6 questions you can miss to still qualify for the scholarship.
