Step-by-step explanation:

x = number of weeks

so, we need to see, what is the number of weeks it takes for both to have the same balance.

it takes both the same amount of weeks, of course.

so,

250 + 15x = 750 + 10x

15x = 500 + 10x

5x = 500

x = 100

it takes them 100 weeks to have the same amount of money in their accounts.

The similarities between the expressions in all the three problems is that after opening brackets both of the expressions are the same.

Two expressions are similar if their values after solving are equal.

12. -3 and -(3)

Here, when we open the bracket for -(3), we obtain -3 which is the same as the first expression.

13. -1(7) and -(7)

Solving for the first expression, we get -1×7 = -7 and

-(7) = -7.

We can see that both expressions are similar.

14. -2(4) and -(2•4)

Solving -2(4), we get -2×4 = -8

And, -(2·4) = -(8) which is the same as -8

2304 times 3 goes into 6912 and gives the remainder as 0.

The numerator number in the given division number 6912 by 3 is known as a dividend, and the denominator number is known as a divisor. As a result, 6912 is the dividend number and 3 is the divisor number.

Division is one of the four fundamental mathematical operations, along with addition, subtraction, and multiplication. Division is defined as the splitting of a large group into smaller groups so that each group has an equal number of items. In mathematics, it is an operation used for equal grouping and equal sharing.

Division is a basic arithmetic operation in which a larger number is divided into smaller groups with the same number of items. For example, how many total groups will be formed if 30 students must be divided into groups of 5 students for a sporting event? Such problems are easily solved by using the division operation. Here, we must divide 30 by 5. 30 5 = 6 will be the result. As a result, there will be six groups of five students each.

The speed of the fast plane is 490 mph while the speed of the slow plane is 400 mph

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represent the speed of the fast plane and y represent the speed of the slow plane.

Their speeds differ by 90mph, hence:

x - y = 90      (1)

The planes meet after 3 hours, hence:

3x + 3y = 2670    (2)

From both equations:

x = 490, y = 400

Answer:

She scored 12

therefor she did pass

Step-by-step explanation:

The measures of the angles are <1 = 85, <2 = 105, <3 = 85 and <4 = 105

The diagram that completes the question is added as an attachment

From the diagram, we have

<1 + <2 = 180 degrees --- supplementary angles

Given that

<2 - <1 = 30 degrees

Add the above equations

So, we have

2<2 = 210

Divide both sides by 2

<2 = 105

Substitute <2 = 105 in <2 - <1 = 30

So, we have

105 - <1 = 30

Evaluate

<1 = 85

Also, we have

<3 = <1

<4 = <2

This means that

<3 = 85

<4 = 105

Hence, the measures of the angles are <1 = 85, <2 = 105, <3 = 85 and <4 = 105

Find the horizontal asymptotes by comparing the degrees of the numerator and denominator.

Vertical Asymptotes:

x=−2,2Horizontal Asymptotes:

y=1

No Oblique Asymptotes

Full Explanation

The line x=L is a vertical asymptote of the function [tex] y=\frac{x^{2} + 3 x + 6}{x^{2} - 4}[/tex] if the limit of the function (one-sided) at this point is infinite.

In other words, it means that possible points are points where the denominator equals 0 or doesn't exist.

So, find the points where the denominator equals 0 and check them.

x=−2, check: [tex] \lim_{x \to -2^+}\left(\frac{x^{2} + 3 x + 6}{x^{2} - 4}\right)=-\infty [/tex]

Since the limit is infinite, then x=−2 is a vertical asymptote.

x=2, check: [tex]\lim_{x \to 2^+}\left(\frac{x^{2} + 3 x + 6}{x^{2} - 4}\right)=\infty[/tex]

Since the limit is infinite, then x=2 is a vertical asymptote.

Step-by-step explanation:

this is an exercise to take the logical definition of an operation and apply it.

we have first a triangle operation that simply stands for the sum of the 3 included values divided by 3.

in other words, FYI, it creates the mean value of 3 given numbers.

so, we need to calculate

mean value (7, 4, 4) + mean value (8, 2, 11).

(7 + 4 + 4)/3 + (8 + 2 + 11)/3 = 15/3 + 21/3 = 36/3 = 12

the second calculation is based on a table defining a new operation Delta :

2 Delta 2 = 20

2 Delta 5 = 5

2 Delta 3 = 5

5 Delta 2 = 3

5 Delta 5 = 10

5 Delta 3 = 23

3 Delta 2 = 3

3 Delta 5 = 2

3 Delta 3 = 50

so, now we need to use this to calculate

(5 Delta 2) Delta (2 Delta 3)

3 Delta 5

2

the result is 2.
