Long division
Answer:
x= 3/23
Step-by-step explanation:
10×2+24x-20=x+3
multiply the numbers
20+24-20=x+3
eleminate the opposites
24x=x+3
move the variable to the left
24x-x=3
collect like terms
23x=3
devide both side by 23

Mrs. MaryAnn is giving treat sacks out for Valentines Day. She has 30 pencils and 42 smiley face stickers. Mrs. Maryann wants each treat sack to be identical with no leftovers Whats the greatest number of treat sacks she can make? How many pencils will be in each treat sack? How many smiley face stickers will be in each treat sack?
Answer:
6 number treat sacks and
each sack having 5 pencils and 7 smiley face stickers.
Step-by-step explanation:
Given that:
Number of pencils = 30
Number of smiley face stickers = 42
Mrs. MaryAnn wants to divide everything in identical treat sacks so that there are no leftovers.
To find:
The number of greatest number of treat sacks.
Solution:
First of all, we need to find the Highest Common Factor of the two numbers.
Factorization method:
[tex]30 = \underline2\times \underline3\times 5[/tex]
[tex]42 = \underline2\times \underline3 \times 7[/tex]
Here, the common numbers 2 and 3.
So, highest common factor is [tex]2\times 3 = 6[/tex]
If we divide 30 by 6, we get 5 and
If we divide 42 by 6, we get 7
So, if we take 5 pencils and 7 smiley face stickers in one treat sack and if we make 6 such treat sacks then there will be equal division and no leftovers.
Therefore, the answer is:
6 number treat sacks and
each sack having 5 pencils and 7 smiley face stickers.
A car dealer has 20 Toyota Corollas and 35 Honda Accords left in the parking lot. The dealer wants to arrange the cars in rows so that each row has the same number of vehicles and the same number of vehicles of each type. What is the greatest number of rows that can be formed?
Answer: 5
Step-by-step explanation:
Given: A car dealer has 20 Toyota Corollas and 35 Honda Accords left in the parking lot.
The dealer wants to arrange the cars in rows so that each row has the same number of vehicles and the same number of vehicles of each type
The greatest number of rows that can be formed = GCD(20,35) [GCD= Greatest common divisor]
Since 20 = 2 x 2 x 5
35= 7 x 5
GCD(20,35)=5
The greatest number of rows that can be formed = 5
Sonia wanted to purchase a raincoat that cost 12.00 if there would be an 8% sales tax for the purchase ,how much would the sales tax be (round your answer to the nearest cent )
Answer:
i thing is 1
Step-by-step explanation:
Answer:
$1
Step-by-step explanation:
In order to get the sales tax, you have to perform the multiplication operation by multiplying $12 by 8%.
Let x be the sales tax.
x = $12 x 8%
x = 12 x 0.08
x = 0.96
To round off the answer to the nearest cent, you have to look for the last number in the cents' place. If the number is 5 or above, you have to add 1 to the number next to it. If it's below 5, you just have to copy the values.
In the case above, the last number in the cents' place is 6. This is above 5, so we have to add 1 to 9, which will make it 100 cents or $1.
So, the sales tax is $1.

The wholesale cost of a pair of sandals at a shoe store is $22.60. The markup for the sandals is 45%. What is the selling price of the sandals?
Answer:
The selling price of sandals is: $32.77
Step-by-step explanation:
Mark up is the price that is added to the cost price of a product for profit.
Given
Price of sandals = $22.60
Mark up = 45%
To find the price with mark up, we will find the amount of mark up and then add it to the cost price of sandals.
[tex]Mark\ up = 45\%\ of\ 22.60\\= 0.45*22.60\\=10.17[/tex]
The mark up is $10.17
Now,
[tex]Selling\ price = Cost + mark\ up\\= 22.60+10.17\\=32.77[/tex]
Hence,
The selling price of sandals is: $32.77

how to find the median ?? and explain one problem
Answer:
It's quite simple, let me explain..
Step-by-step explanation:
The median is the middle of a data set, so you would need to find the exact middle of your data set.
If your data set is odd, and has an odd amount of numbers, just get the number exactly in the middle, and that would be your median. But when your data set has an even amount of numbers, it is a bit tricky.
Here's an example:
85, 78, 96, 83, 77
As you can see, this set has an odd amount of numbers, 5 numbers to be exact. The median would be 96 because it is exactly in the middle.
An example of a data set with even numbers would be this:
1, 2, 3, 4
What you would do is add the two numbers in the middle, and divide by two.
In this case, 2 and three are in the middle, so you would add 2 and 3, which is 5. Then you would divide 5 by two which is 2.5
2.5 Would be your median.
Hopefully this made sense, please ask questions if you have any.

Answer:

Step-by-step explanation:
I am not entirely sure because you put an x without any spaces soo I don't know if that supposed to be a variable or multiplication sign. If its a multiplication sign then its 8411 because 36+65=99. 99 x 85=8415. 8415 - 4 = 8411.

Santiago receives $251 Per year and simple interest from three investments. Part is invested at 2% part at 3% and part at 4%. There is $500 more invested at 3% then at 2%. The amount invested at 4% is six times the amount invested at 3%. Find the amount invested at each rate.
Answer:
2% : $400
3% : $900
4% : $5400
Step-by-step explanation:
Given that :
Total interest received = 251
Let investment at 2% = x
At 3% = 500 + x
At 4% = 6(500 + x) = 3000 + 6x
Simple interest :
Principal * rate * time
At 2%:
Simple interest = 0.02x
At 3%:
Simple interest = 0.03 * (500 + x) = 15 + 0.03x
At 4%:
Simple interest = 0.04 * (3000 + 6x) = 120 + 0.24x
0.02x + 15 + 0.03x + 120 + 0.24x = 251
0.29x + 135 = 251
0.29x = 116
x = 116 / 0.29
x = 400
Amount invested at 2% = x = $400
Amount invested at 3% = $500 + x = 500 + 400 = 900
Amount invested at 4% = 3000 + 6x = $3000 + 6(400) = $3000 + $2400 = $5400
