6(x-6)+4=-32+6x solve please?????

Answers

Step-by-step explanation:

first distribute

6x - 36 + 4 = 32 + 6x

combine like terms

6x - 32 = 32+ 6x

subtract 6x from both sides and add 32

0 = 64

therefore no solutions to this problem

Answer:

x = 1/3

Step-by-step explanation:

use the distributive property

6 - 36 + 4 = -32 + 6x

-30 = 4 = -32 + 6x

+32         +32      

2 = 4 + 6x

-4   -4      

-2 = 6x

divide by 6

Answers

Answer:

10.8

Step-by-step explanation:

By sine rule:

[tex] \frac{x}{ \sin 81 \degree} = \frac{7}{ \sin 40 \degree} \\ \\ x = \frac{7 \sin 81 \degree}{ \sin 40 \degree} \\ \\ x = \frac{7 \times0.9876883406 }{0.6427876097} \\ \\ x = \frac{6.91381838}{0.6427876097} \\ \\ x = 10.755992 \\ \\ x \approx 10.8[/tex]

Using the tangent formula we can write as,

Tan 40° = 7 / x

Tan 40 = 0.84

The value of x is 8.3 cm

What are trigonometric identities?

There are three commonly used trigonometric identities.

Sin x = 1/ cosec x

Cos x = 1/ sec x

Tan x = 1/ cot x or sin x / cos x

Cot x = cos x / sin x

We have,

A triangle with angle 40° angle 81° and 7 cm on on side of the triangle.

Using the tangent formula we can write as,

Tan 40° = 7 / x _____(1)

Now,

Tan 40 = 0.84

From (1) we get,

0.84 = 7 / x

x = 7 / 0.84

x = 8.3 cm

Thus,

The value of x is 8.3 cm

Step-by-step explanation:

Given: P= $10000, r = 5% t = 18 years.

given f(x)=50+30x, find f(1), f(2), and f(3)
Please help

Answers

The numbers inside the parentheses are the x values. Replace x with each number and solve.

F(1) = 50 + 30(1)= 50+ 30 = 80

F(2) = 50 + 30(2)= 50 + 60 = 110

F(3) =!50 + 30(3)= 50 + 90 =140

The value of the function f(x) = 50 + 30x at x = 1, 2, and 3 will be 80, 110, and 140.

What is a function?

A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.

The function is given below.

f(x) = 50 + 30x

The value of the function at x = 1, will be

f(1) = 50 + 30 × 1

f(1) = 50 + 30

f(1) = 80

The value of the function at x = 2, will be

f(2) = 50 + 30 × 2

f(2) = 50 + 60

f(2) = 110

The value of the function at x = 3, will be

f(3) = 50 + 30 × 3

f(3) = 50 + 90

f(3) = 140

Thus, the value of the function f(x) = 50 + 30x at x = 1, 2, and 3 will be 80, 110, and 140.

Answers

Answer:

650 gallons after 1 hour

Unit rate:650gallons/hour

Step-by-step explanation:

We are given that

Total capacity of pool=3185 gallon

In 2.5 hours water pool fill=1625 gallon

We have to find how many gallons of water fill in the pool after 1 hour and unit rate.

Using unitary method

1625 gallons of water takes time to fill the pool=2.5 hours

1 gallon of  water takes time to fill pool=[tex]\frac{2.5}{1625}[/tex]hours

3185 gallon of water takes time to fill the pool=[tex]\frac{2.5}{1625}\times 3185[/tex] hours

A chess club plans to sell water bottles to raise $425
they already have $175
if they sell water bottles for $8 each, at least how many bottles do they need to sell in order raise enough money
which inequality represents the situation

Answers

Answer:

31

Step-by-step explanation:

I rounded it down thats it

The equality for this equation is

175 + 8b >/=  425

B = number of bottles required to sell. Now, I don't want to give you the answer but I can assist you in easily finding it. Subtract 175 from both sides

8b >/= 250

Now, divide at from both sides and remove the greater than mark which should mean that in the end it should look like it says

**edited** I mean divide 8 from both sides.

b = ?  

That is the number of bottles they must sell, if it is a decimal, round it up because there is no such thing as a decimal number for selling water bottles.

Matt has 3 different colored T-shirts and 2 different colored shorts

How many outfits can Matt make with these clothes?

Answers

Answer:

Step-by-step explanation:

3 x 2 = 6

Matt can make 6 different outfits with these clothes.

What are the Combinations?

Combinations are the procedures used in mathematics to pick k things from n different items without replacement.

The following formula computes the combinations of k items from n:

(n, k) = n! / k!×(n-k)!

Given that Matt has 3 different colored T-shirts and 2 different colored shorts.

Matt can make 3 x 2 = 6 different outfits with these clothes.

This is because for each T-shirt color, he has 2 options for shorts, and he has 3 different T-shirt colors.

So for each T-shirt color, the number of outfit combinations is 2. And since he has 3 T-shirt colors, the total number of outfits is 3 x 2 = 6.

A new car is purchased for 22300 dollars. The value of the car depreciates at 7.5% per year. To the nearest year, how long will it be until the value of the car is 7700 dollars?

Answers

Answer:

13, i think.

Step-by-step explanation:

use the equation: p( 1 - 7.5/100)^r

p= original amount

r = years

sub in numbers

22300 ( 1- 7.5/100)^r

just sub in different numbers for r till you get closest to your answer

After 13 years the value of the car would be $7700

What is an exponential decay?

"It describes the decrease in an amount by a consistent percentage rate over a period of time."

What is exponential decay formula?

"f(t) = a(1 - r)^t , where t is time, a is the initial value and r is the rate"

For given example,

initial value of the car (a) = 22300

The value of the car depreciates at 7.5% per year.

So, the rate (r) = 7.5%

We can write 7.5 percent as,

7.5% = 7.5/100

        = 0.075

So, r = 0.075

Let 't' represents the number of years

We need to find the number of years when the car value is 7700 dollars.

y = $7700

Using the formula of exponential decay,

⇒ y(t) = a × (1 - r)^t

⇒ 7700 = 22300 × (1 - 0.075)^t

⇒ 0.3453 = (0.925)^t

⇒ t = 13.63

⇒ t ≈ 13

Therefore, after 13 years the value of the car would be $7700

factoring trinomials 6n^2-56n-40

Answers

Answer:

Step-by-step explanation:

Use the Quadratic Formula to find the roots, i.e., the values of n for which 6n²-56n-40 = 0.

Answer:

2(n - 10)(3n + 2)

Step-by-step explanation:

Given

6n² - 56n - 40 ← factor out 2 from each term

= 2(3n² - 28n - 20) ← factor the quadratic

Consider the factors of the product of the n² term and the constant term which sum to give the coefficient of the n- term.

product = 3 × - 20 = - 60 and sum = - 28

The factors are - 30 and + 2

Use these factors to split the n- term

3n² - 30n + 2n - 20 ( factor the first/second and third/fourth terms )

= 3n(n - 10) + 2(n - 10) ← factor out (n - 10) from each term

= (n - 10)(3n + 2)

Thus

6n² - 56n - 40 = 2(n - 10)(3n + 2)

The Capulet's are building a horse stall for their horse, Shaggy. The length, y, of the stall must be more than twice the width, x. However, they only have enough material to build 50 feet of fencing. Write the system of equations or inequalities used to solve it. Identify one option that would meet the criteria.

Answers

Answer:

y = 18

x = 7

Step-by-step explanation:

Since the Capulet's only have a total of 50 feet of fencing then that will also be the maximum perimeter of the fence and cannot exceed that value. Therefore, using the information provided we can conclude the following

y > 2x

y + y + x + x <= 50ft

2x + 2x + x + x <= 50ft

Now that we have these equations we can first solve for x and then solve for y

2x + 2x + x + x <= 50ft

6x <= 50ft   ... divide by 6

x <= 8.33

y > 2 * 8.33

y > 16.66

Therefore, one possible value would be
