I think the answer is (-13, -3) but I am not completely sure!
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
<u>Given</u>:
The sum of 5 consecutive integers is 110.
Let the sequence be x, x + 1, x + 2, x + 3, x + 4
We need to determine the fourth number in the sequence.
<u>Value of x:</u>
Since, the sum of 5 consecutive integers is 110.
Thus, we have;
Adding the like terms, we have;
Thus, the value of x is 20.
<u>Fourth term:</u>
The fourth term of the sequence is x + 3
Substituting x = 20 in the term, we get;
Fourth term = 20 + 3 = 23
Thus, the fourth term of the sequence is 23.
Hey!
-----------------------------------------------------
The x-term has a coefficient of 2: 2x
The z-term has a coefficient of -1: -z
Together: 2x - z
The expression has a constant less than zero = 5 + 2z² (When it says a constant term less than zero you can assume that it can be any number being subtract by z).
Final Answer: 2x - z - 5 + 2z²

Hope This Helped! Good Luck!
Answer:
x = - 1, x = 8
Step-by-step explanation:
Given
8 + 7x - x² = 0 ( multiply through by - 1 and arrange into standard form )
x² - 7x - 8 = 0 ← in standard form
(x - 8)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
x - 8 = 0 ⇒ x = 8
