Step-by-step explanation:
fred got a score of 84 on the test. write a division sentence using negative integers where the quotient represents the number of questions fred answered incorrectly
We are given that:
>perfect score- 100
>number of questions of the test- 25
>worth of each question- 4 points
>Fred's score- 84
Let us say that n- number of questions Fred answered wrong
The solution:
let us solve for n
>division sentence: (100 ÷ 4 ) - ( 84 ÷ 4 ) = n
(100 ÷ 4 ) - ( 84 ÷ 4 ) = n
25 - 21 = n
4= n
Therefore Fred answered 4 test questions incorrectly.
Final answer:
To create a division sentence expressing the number of incorrect answers as a negative integer, you would divide the total number of questions by -0.16. This implies that Fred answered 16% of the questions incorrectly.
Explanation:
To write a division sentence using negative integers where the quotient represents the number of questions Fred answered incorrectly, we need to first determine the total number of questions on the test. We can assume that a perfect score is 100%. If Fred scored an 84, that implies he got 84% of the questions correct. We do not know the total number of questions, so let's denote the total number as x.
Since Fred got 84 out of 100 percent, that means he answered 16% of the questions incorrectly. In terms of the total number of questions x, he answered 0.16x questions incorrectly. Since he answered these questions incorrectly, and incorrect answers are considered as losses or negatives, we can multiply the total number of questions x by -0.16 to find the number of questions he answered incorrectly. Therefore, the division sentence could be -x/(-0.16) = y, where y represents the number of questions Fred answered incorrectly.

I lost the little piece of paper that had my locker combination written on it! It takes me 10 seconds to try each of the combinations I can think of, and I have tried a total of 15 combinations so far! Looks like I am going to be late for class ...
Define a unit for the length of time spent trying combinations. Then enter a variable for the number of additional combinations tried and use this variable to write an expression for the length of time spent trying combinations.
The unit of time spent trying locker combinations is seconds, with the student already having spent 150 seconds. Introducing a variable x for additional combinations, the total time is expressed as 10x + 150 seconds.
Explanation:Let's define the unit for the length of time spent trying combinations as seconds. Since the student spends 10 seconds on each try, and has tried 15 combinations, that's already 150 seconds spent. Now, let's introduce the variable x to represent the number of additional combinations the student will try. If each additional combination takes 10 seconds to try, then the total length of time spent trying combinations would be 10x seconds for the additional tries. Add this to the initial 150 seconds, and we get an expression for the total time spent as 10x + 150 seconds.

TJ, Max, and Misha are all the same age. The sum of their ages is s years. How old was TJ eight years ago?
Thanks!
Final answer:
TJ's age eight years ago is found by dividing the sum of their current ages, s, by 3 to find each person's age and then subtracting 8. Hence, TJ's age eight years ago is (s/3) - 8.
Explanation:
If TJ, Max, and Misha are all the same age and the sum of their ages is s years, we can establish that the age of each one of them is s/3. To determine how old TJ was eight years ago, we simply subtract eight from his current age.
So TJ's age eight years ago can be calculated as follows:
Find TJ's current age: TJ's age = s/3.
Subtract eight years to find his age at that time: Age eight years ago = TJ's age - 8
Therefore, TJ's age eight years ago = (s/3) - 8.

PLZ HELP The drama teacher wants to estimate how many tickets to sell for a show. The auditorium has 56 rows of seats. There are 32 seats in each row. Which explains whether it makes more sense to find an overestimate or an underestimate to decide how many tickets to sell?
A. It makes more sense to find an underestimate so that some people can enter the auditorium without buying a ticket.
B. It makes more sense to find an underestimate to make sure there are enough seats for everybody who buys a ticket to the show.
C. It makes more sense to find an overestimate to make sure every seat in the auditorium is filled.
D. It makes more sense to find an overestimate so that the show makes the most amount of money it can.
Answer:
The answer is
B. It makes more sense to find an underestimate to make sure there are enough seats for everybody who buys a ticket to the show.

Mariana graphs the function ƒ(x) = x3 − 4x2 − 3x + 18 and sees two zeros: −2 and 3. Since this is a polynomial of degree 3 and she only sees two zeros, she determines that the Fundamental Theorem of Algebra does not apply to this equation. Is Mariana correct? Why or why not?
Answer:
No, the root 3 has multiplicity of 2.
Final answer:
Mariana is incorrect because the Fundamental Theorem of Algebra states that a third-degree polynomial must have three complex roots, and she has found only two real zeros.
Explanation:
Mariana is not correct in her assumption that the Fundamental Theorem of Algebra does not apply to the function ƒ(x) = x^3 − 4x^2 − 3x + 18. The Fundamental Theorem of Algebra states that every non-constant single-variable polynomial with complex coefficients has at least one complex root. This theorem guarantees that a polynomial of degree n has exactly n complex roots, though some of the roots may be repeated and not all of them may be real. In Mariana's case, the polynomial is of the third degree, so it should have three complex roots. She has found two real zeros, −2 and 3. There must be another root, which could also be real or complex. If all roots were real, she would see all three zeros on the graph. If the third root is complex, it will not appear on the real number graph that Mariana is using.
