i don’t know how much she need to make

Answer: Unknown...Well, just simplify.

Step-by-step explanation:

Since it says x and y, that is NOT a number. So the real question is, how can we solve the problem without numbers? Well that's pretty simple and easy. Since we don't know the number, we will just have to simplify. With no actual number, simplifying is basically the answer. Unless, you can find out the answer.

Dan has the amount of money left would be 10 - xy which is the form of an expression.

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

We have to determine the amount of money Dan has left.

We must only generalize since we don't know the exact quantity. Having no method of solving,

Dan had $10. He bought x pencils, each costing y cents which are given in the question.

quantity of pencils = x and cost of pencil = y

As per the given condition, the required solution would be:

⇒ remaining amount = 10 - quantity of pencils × cost of pencil

⇒  remaining amount = 10 - (x) × (y)

⇒  remaining amount = 10 - xy

Therefore, Dan has the amount of money left would be 10 - xy which is the form of an expression.

Answer:

There are 3 DVD s that can be bought with under $100.

Step-by-step explanation:

Since we have given that

Cost of DVD = $15.99

Cost of Shipping = $ 9.99

Total cost per DVD would be

$15.99 + $9.99 = $ 25.98

Amount he has to spend no more than $ 100.

So, number of DVDs would be

100 ÷ 25.98 = 3.84

Hence, there are 3 DVD s that can be bought with under $100.

Answer:

Step-by-step explanation:

Let the submarine's speed be x km/h

the time taken by the submarine is given as 5 hours

the aircraft travels 10km/h faster than the submarine= 15km/h

time taken by the aircraft is 2hours

therefore the distance covered by both vehicles can be described using the expression below

we know that distance=velocity*time, so equating the two vehicles distance to 110km we have

5*x+15*2=110

5x+30=110

solving for x we have

5x=110-30

5x=80

divide both sides by 5 we have

x=80/5

x=40km/h

The submarine's speed is 40km/h

Answer:

2016

Step-by-step explanation:

To solve this problem, let us find the prime factors of the given numbers:

             96

        8   x    12

  2 x 2 x 2      2 x 2 x 3

              2⁵ x 3

             144

       12     x      12

  2 x 2 x 3       2 x 2 x 3

              2⁴  x 3²

                126

        2       x       63

      2                  7 x 9

     2                 3 x 3 x 7

            2 x 3² x 7

So, the lowest common multiple  =  2⁵ x 3² x 7  = 2016

Answer:

B. No, Jill is not correct, the fraction is equivalent to 0.023.

Step-by-step explanation:

The given fraction is [tex]\frac{23}{1000}[/tex]

Observe that in the denominator there is 1000, which has three zeros after 1.

In changing the given fraction to decimal, there must be 3 significant digits after the decimal.

According to this option (b) is correct.

Moreover, when 23 is divided by 1000, we have

[tex]\frac{23}{1000}=0.023[/tex]

But Jill says that 23/1000 can be written as 0.23, so, Jill is not correct.

Hence option (b) is correct,

Answer:

34

Step-by-step explanation:

10+2=12

12 on both sides=24

5 on both sides=10

10+24=34

The perimeter of the rectangle is 34 for the given sides.

The rectangle is defined as a quadrilateral having four sides and the angle suspended by all the sides is equal to 360 degrees. The perimeter is the sum of all the sides of the rectangle.

Given that the two sides of the rectangle are 5 and x + 2. The value of x is 10.

The perimeter of the rectangle will be calculated as:-

L = 10+2=12

12 on both sides=24

5 on both sides=10

Perimeter = 10+24=34

Therefore, the perimeter of the rectangle is 34 for the given sides.

Answer:

m = 7

Step-by-step explanation:

The 3 given angles lie on a straight line, thus sum to 180° , then

8m - 4 + 90 + 5m + 3 = 180, that is

13m + 89 = 180 ( subtract 89 from both sides )

13m = 91 ( divide both sides by 13 )

m = 7

Here are the elasticities of demand in the following situations :

The demand for flat-screen is elastic.

The demand for bread is inelastic.

The demand for drug is perfectly inelastic.

Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.

Price elasticity of demand = percentage change in quantity demanded / percentage change in price  

Types of elasticity of demand are :

1. Elastic demand : If the absolute value of price elasticity is greater than one, it means demand is elastic. Elastic demand means that quantity demanded is sensitive to price changes.  

If demand is elastic and price is decreased, quantity demanded would increase. The increase in quantity demanded would be greater than the decrease in demand and this would lead to an increase in revenue.

2. Inelastic demand : Demand is inelastic if a small change in price has little or no effect on quantity demanded. The absolute value of elasticity would be less than one.

3. Unit elastic demand : Demand is unit elastic if a small change in price has an equal and proportionate effect on quantity demanded.

4. Perfectly elastic demand : when demand is perfectly elastic, demand falls to zero when price increases

5.Perfectly inelastic demand :  demand is perfectly inelastic when there is no change in the quantity demanded regardless of changes in price.

The demand for flat-screen is elastic. This is because when the price of the television was decreased, demand increased significantly

The demand for bread is inelastic. This is because the fall in quantity demanded was less than than the decrease in the price of bread

The demand for drug is perfectly inelastic. This is because there is no change in the quantity demanded when the price of the drugs was increased.

Answer:

y = -1/2x +6

Step-by-step explanation:

We can use the slope intercept form of a line

y = mx+b where m is the slope and b is the y intercept

y = -1/2x +b

Substitute the point into the equation

9 = -1/2 (-6) +b

9 = 3+b

9-3 =b

6 =b

y = -1/2x +6
