Answer:
First you need to make 3 1/2 into a improper fraction so you multiply 3 x 2 and then add 1 which is 7/2. Next you need to divide it by 5/8. So to divide fraction you have to do K.C.F. (Keep, change, flip). So you keep the 7/2 change the division symbol to a multiplication symbol. and then flip the 5/8 into 8/5. So the whole problem would be 7/2 x 8/5. next you just multiply.
7 x 8 = 56
2 x 5 = 10
next you just need to simplify into the smallest fraction and you can simplify both by 2. So 56 / 2 = 28 and 10 / 2 = 5. That's how the solution is 28/5.
Also, the value of the expression 5 x 8/5 is 25/8.
Answer:
make 3 1/2 into a improper fraction by multiplying the 3 and the 2 in the denominator together and then add 1 in the numerator to get 7 then make it 7/2 since the 2 was the denominator in the mixed fraction. Then keep the 7/2 the same turn the division symbol to a multiplication symbol then turn the 5/8 into 8/5 by flipping it then multiply. 7×8= 56 2×5=10 now you have 56/10 so you need to simplify. 2 is common between 56 and 10 so you multiply 56/10 and 2 together. 56÷2= 28 and 10÷2= 5 so now it is 28/5.

Step-by-step explanation:
So basically when you have to calculate the quarters you need to first of all the data. So this modern number first and then so in this case will be 000 and so on. Then you have to find the position. So in this case you have Around 40 value. So In this case for example the first one will be the 10th value in this case. Day 20th In this case the 30th. So for example 25% of the data of the first party will be until six. So you know 25% of the others will be six or below six. 50% of the data will be in the 20th position. So it will be below nine Or nine and 75% of data will be below or equal to 16. 16. Anything couple of 16 will be in the top 25% and those are dancers. So this is a quick summary. Remember that you find these values When you calculate the 75% position. That in this case because you have 40 values that will be 30%. For the second quarter will be the 50% and for the first quarter will be the 25%. How do you know that? 1st? You need to sort all the data. So the first smallest bodies will be here from smaller to larger and then you find the relative position paid on this percentage.
Gabriels spent $83.97 on three jackets. Each jacket costs the same amount. Write an algebraic equation to show the cost of one
jacket.
Answers
Total cost = number of jackets bought x price per jacket.
83.97 = 3x
Divide both sides by 3
X= 83.97/3

To add fractions, we have to find the common denominator between the two fractions. For this one, it is 15; 5 has the least common multiple of 15 which shares with 3. So in order to make the first fraction have the denominator of 15, we have to multiply the numerator and the denominator by 3. We get 3/15. For the second, we have to multiply the numerator and denominator by 5. We get 10/15. Now that we have fractions with the same denominators, we just add the numerators together and then simplify. 3 + 10 = 13.
1/5 + 2/3 = 13/15

What are the rules of trichotomy???
Answers
Answer:
Step-by-step explanation:
The answer is in the attachment.
Besides this, there are more rules of trichotomy.
Answer:
Let us consider any two numbers 6 and 9 then we have the relation.
[tex] \gray{ \frak{9 > 6 \: \: \: or \: \: \: 6 < 9}}[/tex]
Rule 1.
Adding 2 on both sides then;
[tex] \frak{ \gray{9 + 2 > 6 + 2 \: \: \: or \: \: \: 6 + 2 < 9 + 2}}[/tex]
[tex]\frak{ \gray{ \therefore \: 11 > 8 \: \: \: or \: \: \: 8 < 11}}[/tex]
Both are true for addition.
Thus,when equal number is added to both sides of trichotomy symbol,the symbol remains the same.
Rule 2.
Subtracting 2 on the both sides then,
[tex]\frak{ \gray{9 - 2 > 6 - 2 \: \: \: or \: \: \: 6 - 2 < 9 - 2}}[/tex]
[tex]\frak{ \gray{\therefore \: 7 > 4 \: \: \: or \: \: \: 4 < 7}}[/tex]
Both are true for subtraction.
Thus,when equal number is subtracted to both sides of trichotomy symbol,the symbol remains the same.
Rule 3.
Multiplying both sides by 2 then,
[tex]\frak{ \gray{9 \times 2 > 6 \times 2 \: \: \: or \: \: \: 6 \times 2 < 9 \times 2}}[/tex]
[tex]\frak{ \gray{ \therefore \: 18 > 12 \: \: \: or \: \: \: 12 < 18}}[/tex]
Both are true for multiplication by positive numbers.
But if we multiplied by -2 then there will be,
[tex]\frak{ \gray{ - 18 > - 12 \: \: \: or \: \: \: - 12 < - 18}}[/tex]
These are not true.
To be true,there must be:
[tex]\frak{ \gray{ - 18 < - 12 \: \: \: and \: \: \: - 12 > - 18}}[/tex]
Thus,when both sides of trichotomy symbol are multiplied by equal positive number then the symbol remains the same.When both sides of trichotomy symbols are multiplied by equal negative numbers then the symbol changes as follows:
'<' Changes to'>' and '>' Changes to'<'.
Similarly check for division then get the same result as in multiplication.
Thus,when both sides of trichotomy symbol are divided by an equal positive number, the symbol remains the same.When both sides of trichotomy symbol are divided by an equal negative number,the symbol '<' is changed to'>' or '>' is changed to'<'.

8(2x – 10) = 28
What is the steps to complete?
Answers
Answer:
6.75
Step-by-step explanation:
first let's simplify whatever is inside the parantheses
8(2x-10)=28
8*2(x-5)=28
16(x-5)=28
now we divide both sides by 16 to get rid 16
x-5 = 28/16
now move -5 to the right side
x = 28/16 + 5
x = 28/16 + 80/16 = 108/16 = 6.75
16x - 80 = 28
Then, get x to be the only value on its side
16x = 108
Next, divide
x = 108/16
Finally, simplify
x = 27/4
