Answer: 0=0

Step-by-step explanation:

4(2x-15) = 2(4x-30)

Simplify

8x-60=8x-60

Add 60 to both sides

8x=8x

Answer: 0=0

So the answer is infinite. Theres an infinite about of answers for x.

Answer:

The result of your question would equal: 0 = 0

Step-by-step explanation:

First lets distribute them!

4(2x - 15) = 2(4x - 30)

8x - 60 = 2(4x - 30)

8x - 60 = 2(4x - 30)

8x - 60 = 8x - 60. :

4(2x - 15 = (4x - 30)

8x - 60 = 8x - 60.

Add:

8x - 60 = 8x - 60

8x - 60 + 60 = 8x - 60 + 60

Simplifying:

8x - 60 + 60 = 8x - 60 + 60

8x = 8x - 60 + 60

Again:

8x = 8x - 60 + 60

8x = 8x  =

8x - 60 + 60 = 8x - 60 + 60

8x = 86

Subtracting:

8x = 8x

8x - 8x = 8x - 8x

Simplifying again...

Combining like terms

8x - 8x = 8x - 8x

0 = 8x - 8x

0 = 8x - 8x

0 = 0

The answer equals:

0 = 0

The angle 4 is equal to 98degree.

Two angels whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two-two angles are two pairs of supplementary angles. That means, if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.

Given;

m∠3=82

Now

m∠3+m∠4=180      (since the angles are supplementary)

82+m∠4=180

m∠4=180-82

m∠4=98degree

Therefore, the angle 4 will be 98degrees.

Step-by-step explanation:

The value of θ from the triangle ABC is θ = 6.213°

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let the triangle be represented as ABC

Now , the opposite side of the triangle AB = 2,000 feet

The hypotenuse of the triangle AC = 3.5 miles

The hypotenuse of the triangle AC = 3.5 x 5,280

The hypotenuse of the triangle AC = 18,480 feet

Now , from the trigonometric relations ,

sin θ = opposite / hypotenuse

Substituting the values in the equation , we get

sin θ = 2000 / 18480

On simplifying the equation , we get

sin θ = 0.108225

Taking inverse on both sides of the equation , we get

θ = sin⁻¹ ( 0.108225 )

θ = 6.213°

Hence , the value of θ is 6.213°

Answer: A: 3/10 of the school has blonde hair. B: there are 120 students

Step-by-step explanation: I might have done this wrong but anyway, I multiplied 2/5 by 1/4 and got 1/10, meaning 1/10 of the boys have blonde hair. I multiplied 3/5 (because 5/5 - 2/5 = 3/5) by 1/3 and got that 2/10 of the girls are blonde. I added these, and got that 3/10 of the school are blondes. That's A. Then, I set up the equation 3/10 = 36/x (x equals the total number of students in the school). When I solved it I got x = 120, meaning there are 120 students in the school.

a. The average cost per ton is increasing as the size of the load increases.

b. For a 9-ton truck, the average cost per ton is $45. For a 16-ton truck, the average cost per ton is $60. For an 18-ton truck, the average cost per ton is $65.

This question uses the concept of linear functions.

The equation A(n) = 15n+30 is an example of a linear function, as it is a function of the form f(x) = mx + b, where m is the slope and b is the y-intercept.

The graph of this equation is a straight line, which shows that the average cost per ton is increasing as the size of the load increases.

a. To determine whether the average cost per ton is increasing or decreasing as the size of the load increases, we can look at the graph provided.

The graph shows that as the size of the load increases, the average cost per ton increases.

Therefore, the average cost per ton is increasing as the size of the load increases.

b. To calculate the average cost per ton for each truck, we can use the equation A(n) = 15n+30. For a 9-ton truck, we plug in n = 9 and calculate A(9) = 15(9) + 30 = 135 + 30 = 165. Therefore, the average cost per ton for a 9-ton truck is $45.

For a 16-ton truck, we plug in n = 16 to calculate A(16) = 15(16) + 30 = 240 + 30 = 270.

Therefore, the average cost per ton for a 16-ton truck is $60.

For an 18-ton truck, we plug in n = 18 to calculate A(18) = 15(18) + 30 = 270 + 30 = 300.

Therefore, the average cost per ton for an 18-ton truck is $65.

Answer:

A. The original value of the gift card is 75 dollars, which is the y-intercept of the function.

B. The student spent 2.5 dollars each day at the coffee shop, which is the coefficient of n in the function.

C. After 20 days, the remaining value of the gift card is -2.5 * 20 + 75 = 25 dollars.

D. To find the total number of days until the gift card was used up, we need to find when f(n) = 0. Setting the function equal to 0 and solving for n, we get: 0 = -2.5n + 75, so n = (75)/(-2.5) = 30 days.

Answer:

x = - 5/9

Step-by-step explanatiion:

8x-8+3(2x+2) = -4(x+3) is the original equation

Consider each term and simplify

3(2x+2) = 6x + 6

-4(x + 3) = -4x - 12

Therefore the original expression becomes:
8x - 8 + 6x + 6 = -4x - 12

Move -4x to the left side; becomes + 4x
4x + 8x - 8 + 6x = -12

Group like terms on left side and simplify
(4x + 8x + 6x) (-8 +6) = -12

18x - 2  = - 12

Move -2 to right side -> becomes +2

18x = 2 - 12 = - 10

x = -10/18 = - 5/9

The values will be Loan amount=$186900, When simple interest is 6% then monthly payment=$1453.66 per month, When simple interest is 7% monthly payment=$1609.4 per month

Simple Interest is an easy method of calculating the interest for a loan/principal amount. Simple interest is a concept that is used in many sectors such as banking, finance, automobile, and so on. When you make a payment for a loan, first it goes to the monthly interest and the remaining goes towards the principal amount.

Simple interest formula is given as:

SI=P*R*T/100

Where SI = simple interest

P = principal

R = interest rate (in percentage)

T = time duration (in years)

In order to calculate the total amount, the following formula is used:

Amount (A) = Principal (P) + Simple Interest (SI)

Now,

Initial amount=$237000

Down-payment=20%=20/100*237000=$47400

Amount left=237000-47400=$186900

So, Loan amount=$186900

For interest rate=6%

Total amount=186900+186900*6*30/100

=186900+336420

Total amount=$523320

Therefore, monthly payment=523320/360

monthly payment=$1453.66 per month

For interest rate=7%

Total amount=186900+186900*7*30/100

=186900+392490

Total amount=$579390

Therefore, monthly payment=579390/360

monthly payment=$1609.4 per month

Answer: 2x+10

same expression, just simplified

The monthly payment  for a 30-year loan with a fixed rate of 5% is $702.

Divide the number of payments you make annually by 30, the length of the loan. For instance, 30 x 12 equals 360. Over the course of the loan, you will make 360 payments.

The following equation is used to determine the down payment: down payment = down payment percentage times purchase price. For the sake of this calculation, the down payment percentage must be converted to a decimal.

Purchase price for a house is $210,600

Down payment is 20%.

remaining payment  80% of total price = $210,600*80/100= $168480.

$168480 payment for a 30-year loan with a fixed rate of 5%

then interest will be

interest = 168480 *5*30/100=  $84240

total amount to be paid 30 yr=  168480+ 84240= $252720

Step-by-step explanation:

Step-by-step explanation:

first step : convert both terms into real fractions (not mixed numbers).

second step : bring both fractions to the same denominator (bottom part).

third step : perform the addition.

1.

2 2/3 = (2×3 + 2)/3 = 8/3

2 1/6 = (2×6 + 1)/6 = 13/6

2.

we bring both fractions to .../6.

remember, we need to do the same multiplication for the numerator and the denominator to keep the overall value of the fraction unchanged.

to get from 3 to 6 we need to multiply by 2.

so,

8/3 = 8/3 × 2/2 = 16/6

3.

16/6 + 13/6 = 29/6

if you want to convert this to mixed numbers, this would be
