Answer:

11x-4

Step-by-step explanation:

f(x)=-3x

g(x) = 2x-1

4g(x) - f(x)

4(2x-1) - ( -3x)

Distribute

8x -4 +3x

Combine like terms

11x-4

Here, we are provided with two polynomials f(x) and g(x),and we need to find 4g(x) - f(x).

Given,

Now,we need to find 4g(x) - f(x). We will simply substitute the given value of polynomials to get the answer.

[tex]4g(x) - f(x)[/tex]

[tex]4(2x - 1) - ( - 3x)[/tex]

Opening the parentheses,

[tex]8x - 4 + 3x[/tex]

Now combing the like terms, and adding them,

[tex]8x + 3x - 4[/tex]

[tex] \boxed{11x - 4}[/tex]

This is our final result.

Answer:

10,800

Step-by-step explanation:

9*2= 18

18*600=10,800

10,800 is the stadium's maximum ingress throughput.

The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.

Given, Woodley Stadium has nine gates with two ticket booths at each gate.

So, the total number of booth's at Woodley stadium = 9*2

the total number of booth's at Woodley stadium = 18

Since each ticket booth can process 600 fans per hour

Thus,

the stadium's maximum ingress throughput = 18 *600

the stadium's maximum ingress throughput =  10,800

Therefore, 10,800 is the stadium's maximum ingress throughput.

Answer:

10 blocks

Step-by-step explanation:

The distance of Becky from the school is 10 blocks.

Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

We have been given that Becky leaves school to go home. She walks 6 blocks North and then 8 blocks west.

According to the given situation, we can plot the diagram which has been attached below.

As per the figure, we have a right triangle that has :

AB = 8 blocks, and BC = 6 blocks

The distance of Becky from the school is equal to the length of AC.

By Pythagoras's theorem,

AC² = AB² + BC²

AC² = 8² + 6²

AC² = 64 + 36

AC² = 100

AC = 10 blocks

Therefore, the distance of Becky from the school is 10 blocks.

Answer:

5:2

Step-by-step explanation:

In centimetres

convert 2 m to cm which will be 200 cm

then simplify 200 cm:80 cm --> 5:2

(we cancelled out the zero --> 20:8 then divide 20/2= 10 and 8/2= 4

again the same --> 10/2= 5 and 4/2= 2.

5 and 2 are prime numbers which have no other factor except for 1 and themselves so it cannot be simplified further.

Therefore your answer is 5:2

In metres

convert 80 cm to m which will be 0.8 m

the same steps: simplify 2:0.8

to remove the decimal move the decimal place one to the right --> 8

so you also have to move the decimal place to the right for the numerator: 20

20/8 = 5/2

Explication étape par étape:

Vitesse = Distance / Temps

Distance donnée = 200 km

Durée = 2 h 30

Convertir le temps en heures

Depuis 60 minutes = 1h

2 heures 30 minutes = 2+ (30/60)

2h30 = 2 + 1/2 hors

2 heures 30 minutes = 2,5 heures

Vitesse en km / h = 200 km / 2,5 h

Vitesse en km / h = 80 km / h

D'où sa vitesse moyenne en km / h est de 80 km / h

a) Distance = Vitesse * Temps

Vitesse donnée = 80 km / h

Durée = 3h15

Temps = 3 15/60 h

Durée = 3,25 h

Distance = 80 * 3,25

Distance parcourue en 3h15 = 260 km

b) Distance = Vitesse * Temps

Vitesse donnée = 80 km / h

Durée = 42 minutes

Durée = 42/60 h

Distance = 80 * 42/60

Distance = 3360/60

Distance = 56 km

Distance parcourue en 42 minutes = 56 km

c) Distance = Vitesse * Temps

Vitesse donnée = 80 km / h

Durée = 3 h 36 minutes

Temps = 3 36/60 h

Durée = 3,6 h

Distance = 80 * 3,6

Distance = 288 km

Distance parcourue en 3 h 36 min = 288 km

d) Distance donnée = 540 km

Vitesse = 80 km / h

Temps = Distance / Vitesse

Heure = 540/80

Temps = 6,75 heures

Par conséquent, le temps nécessaire pour parcourir 540 km est de 6,75 heures

Answer:

the answer is C: eleven and forty two ninetieths pounds

Step-by-step explanation:

The total number of pounds of fruit that Frankie bought is 11 + 42/90 pounds, which is the same as option (C), eleven and forty-two ninetieth pounds.

The addition operation in mathematics adds values on each side of the operator.

For example 4 + 2 = 6

To find the total number of pounds of fruit that Frankie bought. Since both amounts are already given in pounds, we don't need to convert them.

Next, we need to add the two amounts together. Six and twelve fifteenth pounds can be written as 6 + 12/15 pounds, and four and four-sixths pounds can be written as 4 + 4/6 pounds. Adding these two amounts together, we get 6 + 12/15 + 4 + 4/6 pounds = 11 + 42/90 pounds.

Therefore, the total number of pounds of fruit that Frankie bought is 11 + 42/90 pounds, which is the same as option (C), eleven and forty-two ninetieth pounds.

Answer:

The answer is 14. Not -14.

Step-by-step explanation:

The value of x for the given triangle will be 14.

The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

Given that the perimeter of the equilateral triangle shown is 67.5 inches. One side of the triangle is 1.75x - 2.

Perimeter = 3 ( 1.75x - 2 )

67.5 = 5.25x -6

x = ( 73.5 / 5.25 )

x = 14

Therefore, the value of x for the given triangle will be 14.

Answer:

[tex]A\approx\$880.68[/tex]

Step-by-step explanation:

So, we know that Jolene bought an initial $750.

We also know that the purchase is increasing at an average rate of 5 1/2 %or 5.5%. In other words, this is being compounded.

So, we can use the compound interest formula, which is:

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]

Where A is the total amount, P is the principal value, r is the rate and n is the number of times compounded per year, and t is the amount of years.

So, substitute 750 for P. 5 1/2% is the same as 5.5% or 0.055 (you move the decimal two places to the left and remove the percent symbol) so substitute this for r. Since it's increasing yearly, n is 1. So, our formula is:

[tex]A=750(1+0.055)^t[/tex]

Add:

[tex]A=750(1.055)^t[/tex]

Since the stock was bought 3 years ago, the value now is t=3. So, substitute 3 for t and evaluate:

[tex]A=750(1.055)^3[/tex]

Evaluate. Use a calculator:

[tex]A\approx\$880.68[/tex]

And we're done!

Formula: A = P(1 + r/n)^t

We have these variables:

P = 750

r/n = 0.055

t = 3

Substitute and simplify:

A = 750(1 + 0.055)^3

A = 750(1.055)^3

A = 880.68

Best of Luck!
