Mr. Green paid $7.50 for a set of dry erase markers. He used a $2.00 coupon for his purchase. Write AND solve an equation that represents the difference between d, the original price of the markers and the coupon. Solve for d.

Answers

Answer 1

Answer:

[tex]d - 2 = 7.50[/tex]

$9.50

Step-by-step explanation:

Given that:

Money paid by Mr. Green for a set of dry erase markers = $7.50

Coupon used for the purchase = $2.00

To find:

The equation and solution to represent the difference the original price [tex]d[/tex] of the markers and the coupon.

Solution:

Given that, the original price of the dry erase markers = $[tex]d[/tex]

Coupon amount = $2.00

Amount paid = $7.50

The equation can be made by subtracting the coupon amount from the original price and comparing it with the amount paid by Mr. Green for the purchase.

Original price = $([tex]d[/tex] - 2)

[tex]d - 2 = 7.50[/tex]

Solving the above equation by adding 2 on both the sides:

[tex]d -2+2= 7.50+2\\\Rightarrow d = \$9.50[/tex]

Step-by-step explanation:

Slope formula:

[tex]m = \frac{y_{2}-y_{1} }{x_{2}- x_{1} }[/tex]

[tex]m = \frac{17 - (-11) }{-1 -(-8) }[/tex]

Answer:

x = 4

Step-by-step explanation:

7x + 16/11 = 4

11 x 7x + 16/11 = 4 x 11

7x + 16 = 44

7x + 16 - 16 = 44 - 16

7x = 28

7x/7 = 28/7

x = 4

Check:

7x + 16/11 = 4

7(4) + 16/11 = 4

28 + 16/11 = 4

44/11 = 4

4 = 4 (note that this number is not the answer, just to check if each side is balanced, the actual answer is 4)

Equality Properties

Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtract Property of Equality

Step-by-step explanation:

Step 1: Define

[tex]\displaystyle \frac{7x + 16}{11} = 4[/tex]

Step 2: Solve for x

Multiply 11 on both sides:                    [tex]\displaystyle 7x + 16 = 44[/tex]Subtract 16 on both sides:                  [tex]\displaystyle 7x = 28[/tex]Divide 7 on both sides:                       [tex]\displaystyle x = 4[/tex]

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x:                    [tex]\displaystyle \frac{7(4) + 16}{11} = 4[/tex][Frac] Multiply:                    [tex]\displaystyle \frac{28 + 16}{11} = 4[/tex][Frac] Add:                          [tex]\displaystyle \frac{44}{11} = 4[/tex][Frac] Divide:                      [tex]\displaystyle 4 = 4[/tex]

Here we see that 4 does indeed equal 4.

∴ x = 4 is the solution to the equation.

A house worth £80,000 in January 2012 is set to decrease in value by 7% per year.

A more optimistic forecast suggests that the value of the house will increase by 4% per year. According to this forecast, how much will the house be worth in January 2015?

Answers

Answer:

The house would be worth £89989.12 in January 2015.

Step-by-step explanation:

With respect to the optimistic forecast, the value of the house will increase by 4% per year.

For the first year (January 2012 to January 2013),

4% of £80000 = 0.04 x £80000

                      = £3200

The cost of the house = £80,000 + £3200

                                     = £83200

For the second year (January 2013 to January 2014), we have;

4% of £83200 = 0.04 x £83200

                        = £3328

The cost of the house = £83200 + £3328

                                    = £86528

For the third year (January 2014 to January 2015), we have;

4% of £86528 = 0.04 x £86528

                        = £3461.12

The cost of the house = £86528 + £3461.12

                                     = £89989.12

According to the forecast, the house would be worth £89989.12 in January 2015.

Answer:

x = 2

Step-by-step explanation:

In the given figure

∵ ABC is a triangle

D is a point on side AB

E is a point on side BC

∵ DE // AC

∵ AC is the third side of the triangle

→ That means DE divides the sides AB, BC into parts that have the same ratio

∴ [tex]\frac{BD}{DA}[/tex] = [tex]\frac{BE}{EC}[/tex]

∵ BD = 6 and DA = 4

∵ BE = x + 1 and EC = x

→ Substitute them in the ratio above

∴ [tex]\frac{6}{4}[/tex] = [tex]\frac{x+1}{x}[/tex]

→ By using the cross multiplication

6 × x = 4 × (x + 1)

∴ 6x = 4(x + 1)

∴ 6x = 4(x) + 4(1)

6x = 4x + 4

→ Subtract 4x from both sides

∵ 6x - 4x = 4x - 4x + 4

∴ 2x = 4

→ Divide both sides by 2 to find x

x = 2

At a lemonade stand, pink lemonade costs $2.50 and sweet tea lemonade costs $4. In one morning, the stand sells 21 drinks for $67.50. How many pink lemonades were sold?

Answers

Answer:

lemonade = 11

Step-by-step explanation:

let p = pink lemonade

let t = sweet tea

create a system of equations -- one with quantity, one with associate costs

p + t = 21      

2.5p + 4t = 67.5

substitution method:  let t = 21 - p

2.5p + 4(21 - p) = 67.5

2.5p + 84 - 4p = 67.5

-1.5 p = -16.5

p = 11

t = 21 - 11

t = 10

amir rented a dvd and it was due to be returned on 28 march he actually returned it to the shop on 16 april the rental shop applies 7p for everyday the dvd is overdue. Work out the total fine paid by amir give your answer in £

Answers

Answer:

£133

Step-by-step explanation:

March had 31 days

Extra days used in March = March 31 - March 28

= 3 days

Extra days used in April = 16 days

Total extra days used = Extra days used in March + Extra days used in April

= 3 days + 16 days

= 19 days

Cost per extra days = £7

Total fine for 19 extra days = £7 × 19

= £133

Total fine paid = £133

The total fine paid by amir should be  £133.

The calculation is as follows:

March had 31 days

Extra days used in March should be

= March 31 - March 28

= 3 days

Now

Extra days used in April = 16 days

And,  

Total extra days used = Extra days used in March + Extra days used in April

= 3 days + 16 days

= 19 days

Cost per extra days = £7

Total fine for 19 extra days = £7 × 19

= £133

Answers

Answer:

Step-by-step explanation:

Change the divisor 3.75 to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend the same, 2 places to the right.

We then have the equations:

5250 ÷ 375 = 14

and therefore:

52.5 ÷ 3.75 = 14

Both calculated to 0 decimal places.

What is m<3? Thank you

Answers

Answer:  143 degrees

===================================================

Explanation:

Let

x = the measure of angle 2y = the measure of angle 3

The goal is to find y

For now, focus on the interior angles of triangle DEF. We have these three angles:

D = 90 (due to the square angle marker)E = angle 1 = 53F = angle 2 = x

Those interior three angles add to 180. This is true for any triangle.

D+E+F = 180

90+53+x = 180

143+x = 180

x = 180-143

x = 37

angle 2 = 37 degrees

Now we can find y.

Focus on angles 2 and 3, which are x and y respectively. These two angles add to 180 because they form a straight line. Note: the triangle's angles summing to 180 is closely related to this idea where angle 2 and angle 3 are a linear pair.

So this means,

(angle2)+(angle3) = 180

x+y = 180

37+y = 180

y = 180-37

y = 143

angle 3 = 143 degrees

It's not a coincidence that we ended up with a previously calculated value of 143. It turns out that adding the remote interior angles D and E leads to the exterior angle EFG.

D+E = 90+53 = 143 = angle EFG

I'm using the remote interior angle theorem. Some textbooks may call this the exterior angle theorem. In my opinion, the phrasing "remote interior angle theorem" is more descriptive.

Answers

Answer:

24= 2*2*2*3= 2^3*3

Step-by-step explanation:

Answer:

prime factorization of 24 = 2 * 2 * 2 * 3 = 2^3 * 3

Step-by-step explanation:

List the first several prime numbers: 2, 3, 5, 7, 11, 13, ...

Now start with 2. Divide 24 by 2 as many times as possible. Then move on to 3, to 5, etc. until you end up with 1.

Divide only by prime numbers.

Start by dividing 24 by 2:

24/2 = 12     12 is divisible by 2, so divide 12 by 2.

12/2 = 6       6 is also divisible by 2, so divide 6 by 2.

6/2 = 3    Since 3 is not divisible by 2, move onto 3.

3/3 = 1      When you get to 1, stop. The prime factors are all the prime numbers in boldface that you divided by.

prime factorization of 24 = 2 * 2 * 2 * 3 = 2^3 * 3
