Help!! I Have No Clue What To Do. Im Struggling And Stuck On This Whole Problem. Can You Please Explain

Answers

Answer 1
First one: Add -3x to each side
Explanation 5x-3x will leave you with 2x on one side and only 7 on the other side of the equal sign
Second one: Multiply each side by 1/3
Explanation: Multiplying by a fraction is the equivalent to dividing. If you divide each number by 3 you are left with
4x + 1 = 2
Third one: Add -3 to each side
Explanation: Since -3 has no variable you can only subtract from the real numbers giving you 7 - 6x = 1 + 5x
Fourth: Multiple each side by -3
Explanation: Multiplication reverses division so multiplying 5x/-3 by -3 eliminates the -3 leaving you with 5x. the other side is just 12, and 12 • -3 = -36
Last one: Multiply by -1/3
Explanation: Like I said earlier, multiplication and division eliminate each other so on the first side it eliminates -3 and on the other side you just preform normal division.
Hope this helps! :)

15. The total mass of 6 similar bags of salt is 4.5 kg. What is the mass of each bag of salt rounded to 1 decimal place? Give the answer in kilograms.

Answers

Answer:

0.7kg

Step-by-step explanation:

Total mass of the bags of salt = 4.5kgnumber of bags of salt = 6

To find the mass of each bag of salt, we divide the total mass by the number of salt bags we have which is 6

Therefore 4.5 ÷ 6 = 0.75 KgMass of each bag of salt = 0.75 Kg

0.75Kg rounded to ONE decimal place = 0.7 Kg

Hope this helps.Good luck ✅.

0.7 kg
6 divided by 4.5 is 0.7 kg

8.3.4 Karl bought five folders from Pay-A-Lot at a cost of $2.50 each. Pay-A-Lot had a 20% -off sale the following day. How much could Karl have saved on the purchase by waiting a day?

Answers

Answer:

Karl could have saved $2.50

Step-by-step explanation:

Cost of folders without the sale: 2.5*5 = $12.50

Cost of folders with the sale: 0.8*2.5 = $2 per folder * 5 folders = $10.00

Difference between prices: 12.5-10 = $2.50

Answer:

2.50$ Karl could have saved on the purchase by waiting a day.

Step-by-step explanation:

Given: total number of folders Karl bought is 5 .

The cost of each folder is 2.50$.

20% off sale the following day at Pay-A-Lot.

we have to find the 20% of each folder and then add them to get the final saving of Karl if he had waited for a day.

Step 1 of 2

20% of 2.50$ is equal to

[tex]$$\begin{aligned}&=2.50 \cdot 20 \% \\&=2.50 \cdot \frac{20}{100} \\&=0.50 \$\end{aligned}$$[/tex]

this is the amount Karl would save on each folder if waited for a day or this is the discount on the amount of 2.50$ that the shopkeeper will give the next day on each

Step 2 of 2

Karl bought 5 folders

so, total savings would be equal to

[tex]$$\begin{aligned}&=5 \cdot 0.50 \\&=2.50 \$\end{aligned}$$[/tex]

HELPPPPPPPP: A car stero that regularly sells for $109 is in sale at a 15% discount. How much is the discount?

Answers

Answer:

Step-by-step explanation:

the discount is $16.35

Answer:

15% = $16.35

Step-by-step explanation:

To find the amount, lets find 10% first. To do so, move the decimal one place to the left.

10%= $10.90

Now, lets find half of 10% value to add it up to deal, 15% off.

10.90/2= 5.45

5%= 5.45

Now, we must add the values of 10% and 5% to find the discount off of the stereo.

10.90 + 5.45 = 16.35

15% = $16.35

Your discounted amount will be $16.35.

Answers

Answer:

x=12

Step-by-step explanation:

[tex]16+20+2x=60\\36+2x=60\\2x=24\\x=12[/tex]

the perimeter is the side lengths added together meaning it is

[tex]16+20+x+x=60[/tex]. x+x can be simplified to 2x. now solve for x

Answer:

x = 12 ft

Step-by-step explanation:

We know that by adding up all of the values of the sides, we will get the value of the perimeter. Using this information, we can set up an equation and simplify to find the variable.

16 + 20 + x + x = 60                         <----- The sum of the sides is the perimeter

16 + 20 + 2x = 60                            <------ Combine variables (x + x = 2x)

36 + 2x = 60                                    <----- Add 16 and 20

2x = 24                                            <----- Subtract 36 from both sides

x = 12                                               <----- Divide both sides by 2

8.37 Sale prices at the Ajax Outlet Store are 50% below original prices. On Saturdays, an additional discount of 20% off the sale price is given. What is the Saturday price of a coat whose original price is $180?

Answers

Answer:

Given:

Sale prices at the Ajax Outlet Store are 50% below the original prices. On Saturdays, an additional discount of 20% off the sale price is given.

To find:

The Saturday price of a coat whose original price is $180.

The formula used to calculate the percentage is (value/total value)*100%.

Step-by-step explanation:

Step 1 of 2

The original price of coat = $180



Ajax always sells at 50% discount

So their sale price = $90

Step 2 of 2

On Saturdays they sell 20% less

Which implies-

1/5*90 = 18

90-18=72

They sell at $72 on Saturday.

180*50=9000
9000/100=90
90*20=1800
1800/100=18
90-18=72
The Saturday sale price of the coat would be $72.

how the poll may be conducted in such a way that the sample is skewed in favor of reversing the prohibition

Explanation:

A reasonable sample is
● selected at random,
● representative of the population, and
● large enough to provide accurate data.

While taking the sample, the number of people who are not favoring the ban on skateboarding should be increased in comparison to the number of people who are in favor of the ban. Doing so will result in a biased sample indicating that majoring of people do not want to ban skateboarding as the sample is projecting a majority who are against the ban instead of favor the ban.

8.45 At some point in the season, the Unicorns had won 60% of their basketball games. After that point, they won 8 more games and lost 2 , to finish the season having won 65% of their games. How many games did the Unicorns play during the season?
Hint: Assign a variable.

Answers

Answer:

The total number of games won by Unicorn is 40.

Step-by-step explanation:

We are given with a word problemWe are asked to find the number of unicorns played during the seasonWe can do this in two steps

         Step 1: Finding the win percentage

         Step 2: Finding the number of unicorns played during the season

Step 1 of 2

Let the number of games played by unicorn be x.The unicorn won 60% of the first x-10 games That is [tex]$\frac{60}{100} \times(x-10)$[/tex]

Combining the 8 games we get,

[tex]$$\begin{gathered}\frac{60}{100}(x-10)+8=\frac{60}{100} \times x-\frac{60}{100} \times 10+8 \\0.6 x-6+8=0.6 x+2\end{gathered}$$[/tex]

Step 2 of 2

The unicorn totally won 65% of the games played.

That is [tex]$\frac{65}{100} \times x=0.65 x$[/tex]

Equating both the equation gives

[tex]$$\begin{gathered}0.6 x+2=0.65 x \\2=0.65 x-0.6 x \\2=0.05 x \\\frac{2}{0.05}=x \\40=x\end{gathered}$$[/tex]

The total number of games won by the unicorn is 40
