Answer:

4

Step-by-step explanation:

First you have to analyze the word equations. Let x equal to Annabell's age and y equal her mother's age

3x + y = 42

6 + 6x = y

Then you use substitution to find x

3x + 6 + 6x = 42

9x = 36

x = 4

Answer:

a) 3n + 2 and b) multiply by 4 and add 5

Step-by-step explanation:

a) 3 x n = 3n
3n + 2 = 3n + 2

b) You can see that the 4 has an x next to it, indicating that you need to multiply the x by 4. Then it also has "+ 5" so you also need to add 5 to the 4x. Finally, you get 4x + 5.

Answer:

Cupcakes     Prices

   5               $7.50

   12              $18

   18              $27

Step-by-step explanation:

Given:

The double number line shows the price of 1 cupcake.

To Find:

Complete the table to show the same information as the double number line.

Solve:

Base on the 1st image:

1 cupcake costs $1.5.

Therefore, we can use the rule of three to complete the table.

If 1 cupcake costs $1.5 then 5 cupcakes would be $1.5 × =$7.50

And 18 cupcakes would be $1.5 × 18 =$27.

Then, 18  ÷ 1.5 = 12

As a result,  12 cupcakes costs $18.

Final Table:

Cupcakes     Prices

   5               $7.50

   12              $18

   18              $27

Kavinsky

The solution is

The price of 5 cupcakes = $ 7.50

The number of cupcakes for $ 18 = 12 cupcakes

The price of 18 cupcakes = $ 27

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is given by

The number line shows the price of one cupcake

The price of 1 cupcake = $ 1.50

So ,

The price of 5 cupcakes = 5 x price of 1 cupcake

Substituting the values in the equation , we get

The price of 5 cupcakes = 5 x 1.50

The price of 5 cupcakes = $ 7.50

And , the number of cupcakes that can be bought for $ 18 is

Number of cupcakes for $ 18 = 18 /  price of 1 cupcake

Substituting the values in the equation , we get

Number of cupcakes for $ 18 = 18 / 1.5

Number of cupcakes for $ 18 = 12 cupcakes

And , the price of 18 cupcakes is = 18 x price of 1 cupcake

Substituting the values in the equation , we get

The price of 18 cupcakes = 18 x 1.5

The price of 18 cupcakes = $ 27

Hence , The price of 5 cupcakes = $ 7.50

The number of cupcakes for $ 18 = 12 cupcakes

The price of 18 cupcakes = $ 27

The perimeter of the larger hexagon, where the smaller hexagon is increased by a factor of 5:7 is: 84 units.

If two shapes are similar, the ratio of their perimeter equals the ratio of their respective sides.

Since the smaller hexagon is increased by a factor of 5:7, therefore:

Length of the larger hexagon = 7/5 × 10 = 14 units.

Perimeter of the larger hexagon = 6(14) = 84 units.

Using translation concepts, the graph of g(x) = |x + 2| is given at the end of the answer.

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, we have that:

f(x) = |x|, h = -2, g(x) = f(x - h)

Hence, the equation of g(x) is:

g(x) = f(x + 2) = |x + 2|.

Answer:

Radius is how far the middle of the circle is from the edge of the circle.  For example, we know that a circle has a middle point and we know that we have a line around it in the shape of a circle.  The radius would be the distance from the middle point to the outer line of the circle.

The cash value of Jim's policy at 15 years and 25 years are equal to $9,000 and $51,000 respectively.

From the table shown in the image attached below, we can deduce that the cash value per unit for 15 years is given as:

15 years = $160.00 per unit.

Next, we would divide the face value of the policy by 1000:

Number of units = 150,000/1000

Number of units = 150.

Now, we can determine the cash value:

Cash value = 150 × 160

Cash value = $9,000.

The cash value per unit for 25 years is given as:

25 years = $340.00 per unit.

Next, we would divide the face value of the policy by 1000:

Number of units = 150,000/1000

Number of units = 150.

Now, we can determine the cash value:

Cash value = 150 × 340

Cash value = $51,000.

Answer:

15 years = 24,000.00

25 years = 51,000.00

Step-by-step explanation:

Hey, I'll explain how you solve these.

Since the value is 150,000, this has to be divided by 1,000.

That gives us 150.

Now you multiply 150 by the 15 yr cash value, which is 160.  

This results in 24,000.00.

Since you have 150, you next need to multiply that by the 25 yr cash value, 340.

That gives us 51,000.00.

Two possible lengths of ribbon (In inches) are 25 and 133  3/4

Step-by-step explanation

Okay, so- First, You need to find out how much ribbon is there before the two additional ones are added. Like this:

12 + 14  2/4 + 14  3/4 = 41  1/4

Next, subtract that amount from 200 to get the number of inches of ribbon that are needed to get 200 inches of ribbon. Like this:

(I changed it to a decimal to make it easier, so don't mind that)

200 - 41.25 = 158.75

So, 158.75 inches of ribbon are needed to get 200 inches. You can subtract any number less than 158.75 from that to get two seperate ribbon measurements.

(This might sound confusing so here)

For example:

158.75 - 25 = 133.75 (The bolded numbers are the two measurements)

158.75 - 65 = 93.75

So, Two possible lengths (in inches) of ribbon that kelly could have added are "25" and "133.75 "

Two possible lengths (in inches) of ribbon that kelly could have added are also "65" and "93.75"
