The answer to 8a. is 17, the answer to 8b. is 3.9, the answer to 8c. is 1 / 2, the answer to 8d. is 7 7 / 8, the answer to 9a. is commutative property, the answer to 9b. is multiplicative identity property, the answer to 9c. is associative property, and the answer to 9d. is additive inverse property.

Regarding the whole "explain using mental math" thing, I pretty much just used the fact that 8a. and 8b. both had the same number of decimal places.

At Anne’s Fabric Emporium, a yard of chiffon fabric cost $7.85. Lee plans to purchase 0.8 yard for a craft or project. How much money will Lee spend on chiffon fabric?

Answers

Okay. So Lee is buying 0.8 yard of fabric from Anne’s and a whole yard costs $7.85. To find out how much it would cost, multiply 7.85 * 0.8. When you do that, you get 6.28. Lee will spend $6.28 on chiffon fabric.

Which statement about the ordered pairs (−9, 3) and (2, −4) is true for the equation 6x−y2=14 ?

(2, −4) is a solution to the equation.
Both ordered pairs are solutions.
Neither ordered pair is a solution.
(−9, 3) is a solution to the equation.

Answers

Neither ordered pair is a solution.
If you solve y^2-6y + 14 = 0 you'll see by the discriminate b^2-4ac
that it is not a perfect square, i.e = -20, so the solutions are imaginary numbers, i.e. no real solutions.

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!

Answers

Let x = TJ's current age.
Therefore each of the three has the same age.
Because the sum of their ages is s, therefore
3x = s
x = s/3

TJ's age 8 years ago is s/3 - 8

Answer: s/3 - 8

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.

My use of distributive is that you have 3 cows and 6 lambs then you have to kill them for meat. But the problem is you have to get twice the meat you usually get. So what do you do? You just cut the meat half the thickness you usually cut. It goes like this 2(3+6)= 18. First add the 3 and 6 together get 9 then multiply 9 by 2 and get 18.

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

Answers

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.

Solve for x: one over eight(8x + 15) = 24

Answers

1/8(8x + 15) = 24

First step is to distribute.
(1/8)*8x + (1/8)*15 = 24
8/8x + 15/8 = 24

Now subtract 15/8 from both sides.
x = 24 - (15/8)
x = (192/8) - (15/8)
x = 177/8
x = 22.125

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.

Answers

Final answer:

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.

One week, the music store sold 2 trumpets, 3 clarinets, and 5 violins for $1240. the next week, they sold 3 trumpets, 1 clarinet, and 4 violins for $1027. the following week, they sold 5 trumpets, 7 clarinets, and 2 violins for $2091. find the cost of a trumpet, a clarinet would, and a violin.

Answers

Trumpet = $174  Clarinet = $149  Violin = $89    Let's write some equations to express what we know.  2t + 3c + 5v = 1240  3t + 1c + 4v = 1027  5t + 7c + 2v = 2091    So we have 3 unknowns and 3 equations. The 2t and 3t are rather interesting in the 1st 2 equations since the 3rd equation has 5t. So if we subtract the 1st and 2nd equations, we can cancel out the t values. So   5t + 7c + 2v = 2091  -( 3t + 1c + 4v = 1027)  = 2t + 6c - 2v = 1064  -(2t + 3c + 5v = 1240)  = 3c - 7v = -176    Now we can express c in terms of v.  3c - 7v = -176  3c = 7v - 176  c = (7/3)v - 58 2/3    Substitute the expression (7/3)v - 58 2/3 for c in the expression 2t + 3c + 5v = 1240 giving  2t + 3((7/3)v - 58 2/3) + 5v = 1240    and solve for t, first distribute the 3  2t + 7v - 176 + 5v = 1240    Merge the v terms  2t + 12v - 176 = 1240    Add 176 to both sides  2t + 12v = 1240 + 176 = 1416    Subtract 12 v from both sides  2t = 1416 - 12v    Divide both sides by 2  t = 708 - 6v    Now substitute both 708 - 6v for t and (7/3)v - 58 2/3 for c in 3t + 1c + 4v = 1027 and solve for v  3t + 1c + 4v = 1027  3(708 - 6v) + (7/3)v - 58 2/3 + 4v = 1027    Distribute the 3  3(708 - 6v) + (7/3)v - 58 2/3 + 4v = 1027  2124 - 18v + (7/3)v - 58 2/3 + 4v = 1027    Combine terms  2065 1/3 - (11 2/3)v = 1027    Subtract 2065 1/3 from both sides   -(11 2/3)v = 1027 - 2065 1/3 = -1038 1/3    Divide both sides by -11 2/3  v = 89    So we know the violins cost $89 each.  Plugging that value into the formula t = 708 - 6v which we created earlier  t = 708 - 6v  t = 708 - 6 * 89 = 708 - 534 = 174    So we know that a trumpet costs $174  Now plug the price of a violin into the formula c = (7/3)v - 58 2/3 to get the cost of a clarinet.  c = (7/3)v - 58 2/3  c = (7/3)89 - 58 2/3 = 207 2/3 - 58 2/3 = 149    And a clarinet is $149    Let's verify  2t + 3c + 5v = 2*174 + 3*149 + 5*89 = 348 + 447 + 445 = 1240  3t + 1c + 4v = 3*174 + 1*149 + 4*89 = 522 + 149 + 356 = 1027  5t + 7c + 2v = 5*174 + 7*149 + 2*89 = 870 + 1043 + 178 = 2091    All the expressions match what was given, so the prices are  Trumpet = $174  Clarinet = $149  Violin = $89

Mr Nemo has 5 desks while Mr Benn has 2 desks

We can say the following
number of desks Mr Benn has = (2/5)*(number of desks Mr Nemo has)
2 = (2/5)*(5)
2 = 2

Which basically is the math translation of "Mr Benn has 2/5 as many desks as Mr Nemo", so that's why choice C is one of the answers.

-----------------

Flip things around and we get

number of desks Mr Nemo has = (5/2)*(number of desks Mr Benn has)
5 = (5/2)*(2)
5 = 5

Note: 5/2 = 2 & 1/2

This is a translation from "there are 2 & 1/2 times as many desks in Mr Nemo's room as in Mr Benn's room" pointing to choice B as the other answer.
