The value of the digit 2 in the number 32,000 is greater than the value of the digit 2 in the number 26,000 by a factor of 10.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The value of a digit in a number depends on its place value.

In the number 32,000, the digit 2 is in the ten thousands place, which has a value of 20,000.

In the number 26,000, the digit 2 is in the thousands place, which has a value of 2,000.

Therefore,

The value of the digit 2 in the number 32,000 is 10 times greater than the value of the digit 2 in the number 26,000.

This is because the ten thousands place is 10 times greater than the thousands place.

In other words,

The digit 2 in the number 32,000 represents 20,000 while the digit 2 in the number 26,000 represents only 2,000.

Thus,

The value of the digit 2 in the number 32,000 is greater than the value of the digit 2 in the number 26,000 by a factor of 10.

Answer:

Emily can deduct $1975 for medical expenses.

Step-by-step explanation:

Emily is itemizing deductions on her federal income tax return and had $5200. Her AGI was $43,000.

We have:

The AGI is =$43,000

Medical expenses amount = $5200

If medical expenses are deductible to the extent that they exceed 7.5% or 0.075  of a taxpayer’s AGI, means  = 43,000 * 0.075 = $3225

Now the deductible amount is  = $5200 - $3225 =  $ 1975

Hence,Emily can deduct $1975 for medical expenses.

Answer:

Emily can deduct the $1,975 in medical expenses from her adjusted gross income.

Step-by-step explanation:

Before an individual could deduct medical expenses as long as they exceeded 7.5% of their adjusted gross income (currently it's 10%).

If Emily's AGI = $43,000, then she will be able to deduct medical expenses that exceed $3,225 (= $43,000 x 7.5%).

Emily's medical expense deductions = $5,200 - $3,225 = $1,975.

If this situation happened this year, Emily would have only been able to deduct $900  [= $5,200 - ($43,000 x 10%)]

Answer:

Katie can bake 48 muffins in 90 minutes.

Step-by-step explanation:

So, as you can see, it says she can bake 24 muffins in 45 mins. Some you make that a fraction:

24/45. The question asks how many muffins she can bake in 90 mins. So, next to the first fraction (proportion) write x/90.

Why x? Because you don't know how many muffins she made, so you'll use that to replace the number for now. X is the numerator because on the last proportion, you put the number of minutes as the denominator. X= how many muffins Katie baked.

So, you cross multiply. Multiply one numerator by the others denominator. Like this: 24×90 and 45×X. Write the answers under the denominator (Ex: 24 X

45 90

-----------

45x = 2160

Now, separate the variable (x) and the constant (45). To do something you must divide. Divide it by 45 to get x. Then, place your equal sign on the right side of that. Now, whatever you do to one side of the equal sign you must do to the other. So, divide 2160 by 45. If done coorectly, you should've gotten 48. X=48 muffins. Therefore, Katie baked 48 muffins.

Final answer:

The perimeter of the rectangle is calculated using the formula P = 2l + 2w, converting the height from millimeters to centimeters and then applying the values to get a perimeter of 70.6 cm.

Explanation:

To calculate the perimeter of a rectangle, we use the formula P = 2l + 2w, where l is the length and w is the width of the rectangle. In this case, the rectangle's length is given as 30 cm, but the height (which can be considered as the width in the context of the perimeter) is given in millimeters. First, we need to convert the height to centimeters by dividing the number of millimeters by 10, because there are 10 millimeters in a centimeter. So, 53 mm is equivalent to 5.3 cm. Now, we apply the formula to find the perimeter:

P = 2 × 30 cm + 2 × 5.3 cm = 60 cm + 10.6 cm = 70.6 cm.

Therefore, the perimeter of the rectangle is 70.6 cm.

Answer:2

Step-by-step explanation:

A solution would be:

[tex](1,32)[/tex]

This is a linear equation written in Slope-Intercept form. Recall that this form, in general, is written as follows:

[tex]y=mx+b \\ \\ \\ Where: \\ \\ m:slope \\ \\ b:y-intercept[/tex]

In this case, we have the following equation:

[tex]y=-4x+36 \\ \\ \\ Where: \\ \\ m=-4 \\ \\ b=36[/tex]

In order to find a solution, let's set [tex]x=1[/tex], so the y-value will be:

[tex]y=-4(1)+36 \\ \\ y=-4+36 \\ \\ y=32[/tex]

So, a  solution to the linear equation is the point [tex](1,32)[/tex]

Final answer:

The solutions to y = -4x + 36 are x = 3 resulting in y = 24, and x = -7 resulting in y = 64, both of which have been verified to be correct by substitution back into the original equation.

Explanation:

To find a solution to the linear equation y = -4x + 36, we can substitute any value for x and solve for y, or vice versa. Let's use the given solutions x = 3 and x = -7 to find the corresponding values for y.

Substitute x = 3 into the equation: y = -4(3) + 36, which simplifies to y = -12 + 36, resulting in y = 24.

Substitute x = -7 into the equation: y = -4(-7) + 36, which simplifies to y = 28 + 36, resulting in y = 64.

To check the validity of these solutions, we back-substitute them into the original equation. For x = 3, the equation becomes 24 = -4(3) + 36, which simplifies to 24 = 24, confirming the first solution. Similarly, for x = -7, the equation becomes 64 = -4(-7) + 36, simplifying to 64 = 64, confirming the second solution. Both substitutions lead to an identity, verifying the correctness of the solutions.

Step-by-step explanation:

The shorter piece is 37 cm

The longer piece is 48 cm:

Step-by-step explanation:

Divide 85 cm by 2 = 42.5

Divide 11 cm by 2 = 5.5

Add them together = 48 cm

85 cm - 48 cm = 37 cm

Length of 1st piece = 37 cm

Length of 2nd piece = x + 11 = 37 + 11 = 48 cm

Now -

Length of smaller piece = 37 cm

Length of larger piece = 48 cm

We have a board which is 85cm in length and must be cut so that one piece is 11cm longer than the other piece.

We have to find the length of each piece, length of the smaller piece, length of the larger piece.

Now -

x + (x + n) + (x + 2n) = 100

3x + 3n = 99

x + n = 33

n = 33 - x

According to the question, we have -

Length of board = 85cm.

Assume that the length of first piece be x. Then -

x + ( x + 11 ) = 85

2x + 11 = 85

2x = 74

x = 37

Hence -

Length of 1st piece = 37 cm

Length of 2nd piece = x + 11 = 37 + 11 = 48 cm

Now -

Length of smaller piece = 37 cm

Length of larger piece = 48 cm

To represent Isiah's age, the variable expression is I = 2J - 3. To represent Kaleb's age, the variable expression is K = 4I.

To write a variable expression for Isiah's age, we start by defining a variable. Let's call Isiah's age 'I'. We are given that Isiah is 3 years younger than twice Jack's age, which can be written as 2J - 3. So, the variable expression for Isiah's age is I = 2J - 3.

To write a variable expression for Kaleb's age, we know that Kaleb is 4 times Isiah's age. Therefore, Kaleb's age can be represented by the variable expression K = 4I, where 'K' represents Kaleb's age and 'I' represents Isiah's age.

Let Jack's age be represented by a variable, let's say j. To express Isiah's age in terms of Jack's age, we use the information given in the question. Isiah is 3 years younger than twice Jack's age, so we can write the expression for Isiah's age as 2j - 3. Following that, we can represent Kaleb's age as being 4 times Isiah's age, which can be expressed as 4(2j - 3).

Answer:

Part a) The number of boxes needed will be 4

part b) The fraction of the box that is empty is [tex]\frac{1}{2}[/tex]

Part c) Are needed 2 cupcakes to fill the last box

Step-by-step explanation:

Part a) How many boxes will be needed for Polly to bring all the cupcakes to the party?

To find out the number of boxes needed, divide the total number of cupcakes by 4 (maximum number of cupcakes that fit in each box).

so

[tex]\frac{14}{4}=3.5\ box[/tex]

Round up

The number of boxes needed will be 4

Part b) If the bakery completely fills as many boxes as possible, what fraction of the last box is empty?

we know that

The maximum number of cupcakes per box is 4

The first three boxes have 4 cupcakes

The last box has

[tex]14-3(4)=2\ cupcakes[/tex]

The fraction of the box that is empty is equal to the number of cupcakes missing to fill the box divided by the cupcake capacity of the box

[tex]\frac{2}{4}=\frac{1}{2}[/tex]

Part c) How many more cupcakes are needed to fill this box

Subtract the number of cupcakes in the box from the cupcake capacity of the box

The last box has 2 cupcakes

The cupcake capacity of the box is 4

so

[tex]4-2=2\ cupcakes[/tex]

therefore

Are needed 2 cupcakes to fill the last box
