Answer: Choice C![a-7 \le 5](https://tex.z-dn.net/?f=a-7%20%5Cle%205)
(a-7 is less than or equal to 5)
and
![a-7 \ge -5](https://tex.z-dn.net/?f=a-7%20%5Cge%20-5)
(a-7 is greater than or equal to -5)
----------------------------------------------------
Explanation:
![|a-7| \le 5](https://tex.z-dn.net/?f=%7Ca-7%7C%20%5Cle%205)
is the same as
![-5 \le a-7 \le 5](https://tex.z-dn.net/?f=-5%20%5Cle%20a-7%20%5Cle%205)
We can use the rule that if
![|x| \le k](https://tex.z-dn.net/?f=%7Cx%7C%20%5Cle%20k)
then
![-k \le x \le k](https://tex.z-dn.net/?f=-k%20%5Cle%20x%20%5Cle%20k)
where k is any positive number
After we get
![-5 \le a-7 \le 5](https://tex.z-dn.net/?f=-5%20%5Cle%20a-7%20%5Cle%205)
, we break it down into two pieces. The first piece is
![-5 \le a-7](https://tex.z-dn.net/?f=-5%20%5Cle%20a-7%20)
while the second piece is
![a-7 \le 5](https://tex.z-dn.net/?f=a-7%20%5Cle%205)
Flip the two sides of
![-5 \le a-7](https://tex.z-dn.net/?f=-5%20%5Cle%20a-7%20)
to get
![a-7 \ge -5](https://tex.z-dn.net/?f=a-7%20%5Cge%20-5)
So we have
![a-7 \le 5](https://tex.z-dn.net/?f=a-7%20%5Cle%205)
and
![a-7 \ge -5](https://tex.z-dn.net/?f=a-7%20%5Cge%20-5)
That's why
the answer is choice CSide Note: we must use the connector "and" instead of "or". Both parts of
![a-7 \le 5](https://tex.z-dn.net/?f=a-7%20%5Cle%205)
and
![a-7 \ge -5](https://tex.z-dn.net/?f=a-7%20%5Cge%20-5)
need to be true, instead of just one part only. This is why we can rule out choice B due to the "or" connector.
4,003 is the correct answer sorry. If I have it wrong 943.000
Answer:
So in each high-school has a first, second and third, and so as the question says, they give 10 points for the first, so get the first and times it by 10 so for example Rosewood high-school had 3 firsts so 3x10=30 and thts the solution to all of them so after getting the 3 answers for each high-school add each school up and find ur answer.Washington high school is 142 points Johnson high school is 159 points
Roosevelt high school is 116
Lewis high school 66. I know u want the full answer but u should figure out which is the most to the least.
P.S.Please check the answer I'm not a professional
