B. 23/5 simplified to 4 3/5

Answer:

B. 23/5

Step-by-step explanation:

4 (whole number) ×5 (denominator) =20

20 + 3 (numerator) = 23

Ans = 23/5

Answer:

-4

Step-by-step explanation:

The order in which you do this addition and subtraction doesn't matter.

Step by step:

12 – 10 + 5 - 11       becomes 2 + 5 - 11, and

2 + 5 - 11 becomes 7 - 11, and

7 - 11 becomes -4

The value of the expression is -44 and thus does not depend on the value of x

An algebraic expression can be described as a mathematical expression made up of variables, terms, factors, coefficients and constants.

They are also made up of mathematical or arithmetic operations, which includes;

From the information given, we have that;

(x-5)(x+8)-(x+4)(x-1)

expand the bracket

x² + 8x - 5x - 40 - (x² -x + 4x - 4)

x² + 8x - 5x - 40 - x² + x - 4x + 4

collect like terms

3x - 3x - 40 - 4

add or subtract like terms

0 - 44

Hence, the expression does not depend o x

Step-by-step explanation:

assuming Lamar didn't buy any other cupcakes outside of the chocolate and vanilla ones mentioned, the expression that gives you the total amount of cupcakes bought for the party is 8 + v. since you don't know the number of vanilla cupcakes Lamar bought, it is represented as the variable v in this problem.

Answer:

52.5

Step-by-step explanation:

Since ABCD is a parallelogram, we know that angle ABC and angle ADC are congruent, and since angle ABC is 105, angle ADC is also 105. Since ADC lies on a line, which is 180 degrees, we can calculate ADE by doing 180 - 105 = 75

Next, we must realize that since ED is equal to AD, then angle AED is congruent to DAE. So now we have the three angles for triangle ADE

x (angle AED), x(angle DAE) and 75(angle ADE)

Since we know that a triangle has 180 degrees, we just formulate the following:

2x + 75 = 180

2x = 105

x = 52.5

The difference of the two polynomials (9x² + 8x) - (2x² + 3x) is 7x² + 5x.

To find the difference of these two polynomials, we need to subtract the second polynomial from the first. This is done by subtracting each term of the second polynomial from the corresponding term of the first polynomial. In this case, we have:

So, the difference of the two polynomials (9x² + 8x) - (2x² + 3x) is 7x² + 5x.

The terms that are being subtracted are the terms that have the same degree, meaning the same exponent of the variable.

It's worth noting that the order of subtraction doesn't change the result and that we can subtract polynomials of any degree and size, and it will work the same way.

Answer:

14 and 16

Step-by-step explanation:

Answer:

There was a discount of 20% on the pair of pants.

Step-by-step explanation:

10% of $34 would be $3.40 meaning 20% would be double, which is $6.80.

If we subtract 20% or $6.80 from the original price $34, we get 34 - 6.80 = 27.20

To solve for x, we need to get x by itself on one side of the equation. To do this, we can start by subtracting 1.4x from both sides of the equation. This gives us:

3 1/2 - 1.4x ≥ 0

Next, we can simplify the left side of the equation to get:

7/2 - 7/5x ≥ 0

Now we can divide both sides of the equation by -7/5 to get:

-5/2x ≤ -7/2

Finally, we can multiply both sides of the equation by -2/5 to get:

x ≥ 4 9/10

Therefore, the solution is x ≥ 4 9/10, which corresponds to answer choice C.

Answer:
x ≥ 4 9/10 C:)

Step-by-step explanation:

The total amount withheld from the student's pay last year in federal tax, state tax, and FICA is $667.50 + $201.25 = $868.75

Percentage is a way of expressing a number as a fraction of 100. It is often denoted using the symbol "%" (percent sign). Percentages are used to express how much of something there is in relation to the whole. For example, if a student answers 80% of the questions correctly on a test, it means they answered 80 out of 100 questions correctly.

A tax is a financial charge imposed by a government on individuals, businesses, or other entities to raise revenue for government spending. Taxes are typically based on a percentage of income or sales, and can be levied on various forms of income, including wages, salaries, and profits. The purpose of taxation is to fund government programs and services, such as roads, schools, and national defense. Taxes can also be used to redistribute wealth and influence economic behavior.

The amount withheld from the student's pay last year in federal tax is $6675 x 0.1 = $667.50

The amount withheld from the student's pay last year in state tax is $6675 x 0.03 = $201.25

The total amount withheld from the student's pay last year in federal tax, state tax, and FICA is $667.50 + $201.25 = $868.75

So the answer is A. 867.75

========================================================

Explanation:

Let's define the following

There are 30 students in the class total. This must mean A+B+C+D = 30.

We know that "There were 7 students who failed the test and also did not complete the assignment", meaning we can say D = 7.

We can also say A+B = 21 because this is the entire group of people who passed the test (whether they did the hw or not).

This means:

A+B+C+D = 30

(A+B)+C+D = 30

(21) + C + 7 = 30

C+28 = 30

C = 30-28

C = 2

We have 2 people who failed the test, but did the hw.

Because 20 students did the hw, we know that

A+C = 20

A+2 = 20

A = 20-2

A = 18

We have 18 students who passed the test and did the hw. This is out of 21 students who passed. From here on out, we only focus on this group of students because of the phrasing "given that they passed the test". This means we know 100% that whoever we picked, they passed the test.

The probability we're after is therefore:

18/21 = (3*6)/(3*7) = 6/7

The term that have the greatest value is

The knowledge of negative and positive number is necessary here.

numbers less than zero are negative while numbers greeter than zero are positive

Negative terms in an odd exponent remains negative hence less than zero in even exponent the negative changes to positive and becomes greater than zero

For the expression aₙ = (-1)ⁿ⁺¹(5)ⁿ the teem that determines whether the expression is greater that zero is  (-1)ⁿ⁺¹. therefore

n + 1 must be even

n must be odd for n + 1 to be even hence the greatest number here is aₙ₊₁₅ a(n+15)

A barracuda swam directly toward a coral reef at a speed of 9.6 seconds. It swam 72 meters. so its speed was 7.5m/s.

Speed can be calculated as the ratio of distance traveled to the time taken.

Speed = Distance/ time taken

A barracuda swam directly toward a coral reef at a constant velocity for 9.6 seconds. It swam 72 meters in that time.

Distance = 72 meters

Time taken = 9.6 seconds

So,

Speed = Distance/ time taken

Speed = 72/ 9.6

           = 720/ 96

           = 7.5m/s

Jeremiah average velocity during the drive was 80 km/h while the instantaneous velocity at one point was 105 km/h

An equation is used to show the relationship between numbers and variables.

Average velocity is the ratio of total distance travelled to total time taken. Instantaneous velocity is the velocity at a particular point in time.

Jeremiah completed a straight, 120 km drive in 1.5 hours, hence:

Average velocity = total distance / total time

Average velocity = 120 km / 1.5 hours = 80 km/h

At one point during the drive, he saw that his speedometer read 105 km/h, hence:

Instantaneous velocity = 105 km/h

The average velocity is 80 km/h while the instantaneous velocity is 105 km/h

Answer:

This is not possible.

Step-by-step explanation:

6 m = 600 cm

A triangle with a 600 cm leg and a 10 cm hypotenuse is impossible

If the 6 m should have been 6 cm, then:

Using the Pythagorean theorem:

base² = 10² - 6² = 100 - 36 = 64

base = √64 = 8

d² = 8² + 15² = 64 + 225 = 289

d = √289 = 17 cm , not meters
