I will put an equation to the corresponding number.
1) Seven more than 2 times a number is 23 => 2n + 7 = 23
2) The difference of 2 times a number and 7 is 23 => 2n - 7 = 23
3) The sum of 7 times a number and 2 is 23 => 7n + 2 = 23
4) Seven less than 2 times a number is 23 => 2n - 7 = 23
Based on the choices. The equation that matches sentences 2 & 4 is letter b. 2n - 7 = 23
Though both sentences are structured differently and used different terms, they both refer to subtraction of 7 from the product of 2 and n to get the difference of 23.
Answer:
The answer to |4a|=20 is a=5 or a=-5.
Step-by-step explanation:
Hi!
This is definitely a trapezoid, as it has two equal sides and two inequal sides. It's not a parallelogram, because two sides eventually intersect. It is a quadrilateral, because it has four sides.
None of the others apply here.

Step-by-step explanation:
1. The level of education as high school diploma (31% area).
Therefore the most frequent education level is High school Diploma.
2. Suppose there are 200 people in random sample. Pie diagram shows the percentage of people with Bachelor's degree is 19%
Therefore the number of people having Bachelor's degree among 200 people = 200×19% = 38
Therefore the answer is 38 .
3. Now the population size given is 6000. The percentage of individuals who have some collage but no degree is 17%
Therefore the number of individuals among 6000 individuals who have some collage but no degree = 6000×17% = 1020
Thereforethe answer is 1020 .
4. The percentage of individuals who have an associate's degree is 9% as per the pie diagram. The above pie diagram is based on a random sample of individuals. If we take another sample then also we may get different result. Therefore if we considere the entire population of U.S.A. the percentage of individuals who have an associate's degree may differ from 9% .
