We first take the absolute value of -7, making 7. This simplifies the equation to 12=w-7. Adding 7 to both sides finds us w=19.

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.
Given:
DE contains the points D(1, -2) and E(3, 4).
FG contains the points F(-1, 2) and G(4, 0).
To find:
Is DE perpendicular to FG.
Solution:
Slope of DE:
Here 
m = 3
Slope of FG:
Here 
<em>Two lines are perpendicular if product their slopes are -1.</em>
Slope of DE × Slope of FG
≠ -1
The solution is no, because the product of the slopes is not -1.
Answer:
5 1/2.
Step-by-step explanation:
11 divided by 2 is 5 with a remainder of 1.
So the mixed number is 5 1/2.
