Given: Gia got some books from the library yesterday. She got 5 books today after returning 3. Gia now has 6 books.

To Find: How many library books did gia begin with.

Solution:

Let the number of library books gia begin with [tex]=\text{x}[/tex]

Number of books gia got today [tex]=5[/tex]

Number of books gia returned  [tex]=3[/tex]

Total number of books Gia has [tex]=(\text{Total number of books is started with})+(\text{number of books gia got})-(\text{books gia returned})[/tex]

                                        [tex]\text{x}+5-3[/tex]

                                         [tex]\text{x}+2[/tex]

Total number of books gia has [tex]=6[/tex]

now,

                 [tex]\text{x}+2=6[/tex]

                 [tex]\text{x}=6-2[/tex]

                 [tex]\text{x}=4[/tex]

Hence number of books gia started with is 4

The number of books Gia started with is 4

Let the number of books she got yesterday = x

Total Number of books she has gotten = 6

Books she got today = 3

Number of books she returned = 5

Expressing this as an equation :

Total books gotten = (x + 5 - 3)

6 = x + 5 - 3

6 = x + 2

6 - 2 = x

x = 4

The number of books Gia started with is 4.

[tex]\frac{0.7}{100}\times119.90=x[/tex]

[tex]x=0.83[/tex]

Hence, Gayle has saved $0.83 so far.

Answer:

She has saved $83.93.

Step-by-step explanation:

Gayle is saving to buy a bicycle.

The cost of bicycle = $119.90

She has saved = 0.7 of $119.90

                        = 0.7 × 119.90

                        = $83.93

The amount she needs more = 119.90 - 83.93

Final answer:

To define the variable in mathematics means to assign symbols to represent quantities that can take various values, either as numerical variables measurable in the same units or as categorical variables for classification purposes. This allows for the exploration of relationships and predictions of outcomes.

Explanation:

In mathematics, the term 'define the variable' refers to the process of assigning a symbol, typically a letter such as X or Y, to represent a quantity that can take on various values. Variables can be of different types, such as numerical variables which represent values measurable in the same units like time in hours or weight in pounds, and categorical variables which classify individuals or items into categories, such as political affiliation.

For example, in the equation of a line y=mx+b, x and y are variables with x usually representing the independent variable plotted along the horizontal axis, and y as the dependent variable plotted on the vertical axis. The variable m represents the slope of the line, and b represents the y-intercept, or the point where the line crosses the y-axis. By defining each variable, a mathematician or an economist can explore the relationship between quantities and predict outcomes.

An example in statistics would be letting X represent the number of children in a family, making it a numerical variable, where each specific number of children would be represented by a lowercase x (0, 1, 2, 3, etc.). Conversely, if Y represents someone's political party, each category (Republican, Democrat, Independent, etc.) is an example of a categorical variable, which does not make sense to average mathematically like numerical variables.

32 rose arrangements and 8 tulip arrangements

8 times 4 = 32

8 + 32 = 40

Heidi's mom made 8 tulip arrangements and 32 rose arrangements. This was determined by setting up equations based on the given information and solving for the number of each type of arrangement.

With 4 times as many rose arrangements as tulip arrangements. Let's denote the number of tulip arrangements as T and the number of rose arrangements as R. According to the information, R = 4T and R + T = 40.

Substituting R in the second equation gives 4T + T = 40, which simplifies to 5T = 40. Solving for T, we find T = 8. Therefore, the number of tulip arrangements is 8. Substituting T = 8 into the equation R = 4T gives R = 32, meaning that there are 32 rose arrangements. Thus, Heidi's mom made 8 tulip arrangements and 32 rose arrangements for the party.

Final answer:

The algebraic equation based on the statement '5 times a number, subtracted from six, is triple the number' is 6 - 5x = 3x. Solving for 'x' gives us x = 3/4.

Explanation:

The student's question involves creating an algebraic equation based on a verbal statement. To translate the statement '5 times a number, subtracted from six, is triple the number' into an equation, let's use 'x' to represent the unknown number. The statement can be written as: 6 - 5x = 3x. To solve for 'x', we need to get all terms involving 'x' on one side and constants on the other. Here's how you can do it:

Add 5x to both sides of the equation to get: 6 = 3x + 5x

Combine like terms: 6 = 8x

Divide both sides by 8 to get the value of x: x = 6/8

Simplify the fraction: x = 3/4

Therefore, the number in question is 3/4.

Answer: Transitive property of Equality.

Therefore if ∠XYZ≅∠PDQ and ∠PDQ≅∠ABC then by transitive property of equality we have ∠XYZ≅∠ABC.

The law of transitivity tells that if a equals to b and b equals to c then a equals to c.

For example If Jane has same height of Susan and Susan has same height of Tina then Jane has same height of Tina.

The statement "∠XYZ ≅ ∠PDQ and ∠PDQ ≅ ∠ABC, so ∠XYZ ≅ ∠ABC" is justified by the Transitive Property of Equality, which indicates that the congruence of the first and third angle is established through their mutual congruence to the second angle.

The property that justifies the statement "∠XYZ ≅ ∠PDQ and ∠PDQ ≅ ∠ABC, so ∠XYZ ≅ ∠ABC" is the Transitive Property of Equality. This property states that if a first thing is equal to a second thing, and the second thing is equal to a third thing, then the first thing is also equal to the third thing.

In the context of angles, if ∠XYZ is congruent to ∠PDQ, and ∠PDQ is congruent to ∠ABC, then by the Transitive Property, ∠XYZ must be congruent to ∠ABC.

As there are 4 different sites so we have 4! possible arrangements to choose from so it becomes = [tex]4\times3\times2\times1=24[/tex]

And there will be only 1 shortest route out of these.

So the probability that the route selected is the shortest route becomes = [tex]\frac{1}{24}[/tex]

The question involves finding the probability of randomly arranging deliveries to four sites such that the arrangement corresponds to the shortest route. With 24 possible arrangements, only one of which constitutes the shortest route, the probability is 1/24.

This question involves the concept of permutations in probability. If delivery sites are being randomly selected, there are 4! (4 factorial) possible sequences for the deliveries, i.e., 4*3*2*1 = 24 different routes.

Assuming that only one of these combinations constitutes the shortest route, the probability of randomly selecting the shortest route is therefore 1 out of 24. To obtain this, you divide the number of favorable outcomes (1 - because there's only one shortest route) by the total outcomes (24 - from 4 factorial).

So, "the probability of selecting the shortest route randomly is 1/24".

Step-by-step explanation:

In 63, 6 is in the tenths place, meaning it represrents the number 60.

In 46, 6 is in the ones place, meaning it represents the number 6.

So, given that, in the first example 6 is x times the value of 6 in the second example:

x = 60 / 6

x = 10

Hope it helped,
