3/x+2 = 2/x−1 pleasee help

Answers

Answer 1

So you have:
[tex] \frac{3}{x} + 2 = \frac{2}{x} - 1 [/tex]

1) Start off by multiplying both sides by x to simplify the problem:
[tex]\frac{3}{x} + 2 = \frac{2}{x} - 1 \\ x(\frac{3}{x} + 2) = (\frac{2}{x} - 1)x\\ 3 + 2x = 2 - x [/tex]

2) Now isolate the x by moving all terms with x onto one side and all other terms onto the other side:
[tex]3 + 2x = 2 - x\\ 3x = -1[/tex]

3) Finally, divide by 3 on both sides to find the value of x:
[tex]3x = -1\\ x = \frac{-1}{3} [/tex]

Answer: x = [tex]\frac{-1}{3}[/tex]

Alexander is riding his bicycle to school. After one mile he is a third of the way there. How much more does he have to ride

Answers

If the question unit is miles, then he has 2 miles to go, the trip total is 3 miles.

You are given
1 mile = (1/3)*(distance to school)
Multiply this equation by 3 and you have
3 mile = (distance to school)

You also know that
(distance ridden so far) +(remaining distance) = (distance to school)
Subsituting given information, this is
1 mile + (remaining distance) = 3 mile
Subtracting 1 mile from this equation gives
(remaining distance) = 2 miles

Alexander has 2 miles more to ride.

but what's the numerator?

Answers

Since there are only 2/15 red marbles in the jar, to draw the first marble it would be a 2/15 chance, the next draw would only have 14 marbles, and only 1 red marble, giving you a 1/14 chance. Then you would just need to multiply those two together giving you 2/210, which you can simplify to 1/110

A car tire has a radius of 15 inches. Suppose the car is traveling at 60 miles per hour (1 mile = 5,280 feet). What is the approximate rate of spin, in revolutions per minute, of the tire? Round the answer to the nearest whole number.

Answers

Radius = r = 15 inches
Speed of the car = v = 60 miles per hour
= 60 x 5280 feet per hour
= 316800 feet per hour
= 316800 x 12 inches per hour
= 3801600 inches per hour
= 3801600/60 inches per minute
= 63360 inches per minute

Angular velocity = w = ?

v = r w
w = v/r

So,

w = 63360/15
= 4224 radians per minute
= 4224/2π revolutions per minute
= 672 revolutions per minute

So, the angular velocity of the tire is 672 revolutions per minute

First find the distance covered in 1 revolution,
Circumference = 2π×15/12 = 7.85398 feet. (1 foot=12 inches)

7.85398 feet = 7.85398/5280 = 0.001487496522 miles

In 1 hour, it travels 60 miles. This means it travels (60/60) miles in 1 minute.

So, it travels 1 mile in 1 minute.

The rate of rotation = 1/0.001487496522
= 672.27rpm

To the nearest whole number = 672 rpm

Answers

There are 50 total patrons. 16 like lattes, 12 like espressos, and 8 like both drinks.

Add the two totals for patrons that like either lattes or espressos:

[tex] 16 + 12 = 28 [/tex]

8 patrons like both drinks, so subtract this from the amount of patrons that like either drink:

[tex] 28 - 8 = 20 [/tex]

20 patrons like at least one drink.

Subtract the amount of patrons that like a drink from the total amount of patrons:

[tex] 50 - 20 = \boxed{30} [/tex]

30 patrons like neither drink.

First we need to find the number of Patrons who like either Latte or Espresso.

n(L) = 16
n(E) = 12
n(L and E) = 8

n(L or E) = n(L) + n(E) - n(L and E)

n(L or E) = 16 + 12 - 8 = 20

Thus 20 like Either of the coffee drinks.

The patrons don't like either of the drinks will be = 50 - 20 = 30

Centennial park is evaluating the capacity of the park and have determined that 15 people can comfortably stand in a section that is 5ft by 8ft , the park has dimensions that are 400yds by 200 yds estimate the number of people who can fit in the park

Answers

If you multiply all those numbers you will get 5.76e9 yds

We have been given that 15 people can comfortably stand in a section that is 5ft by 8ft .

Hence, the area of this section is given by

[tex]A=5\times 8\\ A=40 ft^2[/tex]

Hence, we can say that 15 people can comfortably stand in an area 40 square feet.

Now, we know that 1 yard is equal to 3 feet.

Hence, the area of the section 400yds by 200 yds is equal to

[tex]400\times 3 \times 200 \times 3\\ =720000 ft^2[/tex]

Now, in 40ft^2, 15 people can stand comfortably.

Hence, in 720000 ft^2, number of people can stand comfortably is

[tex]\frac{15}{40} \times 720000\\ \\ =270000[/tex]

Therefore, 270000 people can stand in the park of dimension 400 yds by 200 yds

We can determine the type of triangle from the length of the sides. The length of the sides can be found using the distance formula.

[tex]AB= \sqrt{ (2+3)^{2} + (1-6)^{2} } =5 \sqrt{2} \\ \\ BC= \sqrt{ (9-2)^{2} + (5-1)^{2} } =\sqrt{65} \\ \\ CA = \sqrt{ (-3-9)^{2} + (6-5)^{2} } = \sqrt{145} \\ \\ [/tex]

None of the side lengths are equal, so the triangle formed by the given vertices is a Scalene Triangle. Moreover, the Pythagorean theorem is also not satisfied with given side lengths, so the triangle is NOT a Right Angled Triangle.

If we observe the graph of F(x) and G(x), F(x) can be obtained by shifting the graph of G(x) 4 units down.

Shifting 4 units down means subtracting 4 from the function value.

Thus,

F(x) = G(x) - 4
F(x) = 4 - x² - 4 = - x²

Therefore, the correct answer is option B

Tree a lived for 6 decades and 5 years. Tree b lived for 58 years. Which tree lived longer

Answers

Final answer:

Tree A, which lived for 65 years (6 decades and 5 years), lived longer than Tree B, which lived for 58 years.

Explanation:

To answer which tree lived longer, we can calculate the age of both trees. Tree A lived for 6 decades and 5 years. Since one decade is equal to 10 years, 6 decades would be 6 x 10 years, which is 60 years. Adding the additional 5 years, Tree A lived for a total of 60 + 5 = 65 years.

Tree B lived for 58 years. Comparing both ages, Tree A lived for 65 years while Tree B lived for 58 years. Therefore, Tree A lived longer than Tree B.

Factors of 108 are:
1, 108; 2, 54; 4, 27; 6, 18; 9, 12

Factors of 132 are:
1, 132; 2, 66; 3, 44; 4, 33; 6, 22; 11, 12

As can be observed, the largest number they have in common is 12. Therefore the GCF of 108 and 132 is 12.

A cat and a dog have a race. The cat’s strides are 30% shorter than the dog’s but it makes 30% more strides than the dog. Which of them will win the race?

Answers

The cat travels 0.7 times as far as the dog on each stride, but it takes 1.3 times as many strides in a given time interval. Hence the cat's distance relative to the dog's is 0.7*1.3 = 0.91. This is less distance than the 1 unit the dog covers in the same time.

The dog will win the race.

the answer would be 90% because when you multiply 30% x 30% =90% its the same as 3 x 3 = 9

Simplify (3x+8)(x+1) using a table, the Distributive Property, and the FOIL
method. Which method is most efficient? Explain.

Answers

Foil method:
FOIL stands for
first-multiply the first term in each set of parenthesis
outer-multiply the outer term in each of the perenthesis
inner- multiply the inner term in each of the parenthesis
last- multiply the last term in each of the parenthesis
(3x+8)(x+1)
(3x*x)=3x^2
(3x*1)=3x
8*x=8x
8*1=8
thus we shall have:
3x^2+3x+8x+8
=3x^2+11x+8

Distributive property:

(3x+8)(x+1)
3x(x+1)+8(x+1)
3x^2+3x+8x+8
=3x^2+11x+8

Both methods are efficient, it all depends with the users preference

Final answer:

To simplify (3x+8)(x+1), we can use the FOIL method, the Distributive Property, or a multiplication table, all leading to the same simplified expression: 3x² + 11x + 8. The FOIL method is typically the most efficient for binomials.

Explanation:

The question asks to simplify the expression (3x+8)(x+1) using a table, the Distributive Property, and the FOIL method and to determine which method is most efficient.

Using the FOIL Method

FOIL stands for First, Outer, Inner, Last and represents a quick way to multiply two binomials:

First: Multiply the first terms in each binomial (3x×x = 3x²).

Outer: Multiply the outer terms (3x×1 = 3x).

Inner: Multiply the inner terms (8×x = 8x).

Last: Multiply the last terms in each binomial (8×1 = 8).

Adding these products together, we get 3x² + 3x + 8x + 8, which simplifies to 3x² + 11x + 8.

Using the Distributive Property

This involves expanding the expression by multiplying each term in the first polynomial by each term in the second: (3x+8)(x) + (3x+8)(1), which also simplifies to 3x² + 11x + 8.

Using a Table

Create a table where you list each term of the first polynomial in the first row and the terms of the second polynomial in the first column, and then fill in the table with the products of the intersecting terms. The sum of these products will also yield 3x² + 11x + 8.

While all three methods will give the correct answer, the FOIL method is generally seen as the most efficient for this particular problem, as it provides a straightforward, step-by-step process that is easy to follow and remember for multiplying two binomials.

Daisies cost $0.99 each and tulips cost $1.15 each. Maria bought a boquet of daisies and tulips. It contained 12 flowers and cost $12.52. Find the number of daisies and the number tulips in the bouquet

Answers

Final answer:

Maria bought 8 daisies and 4 tulips in the bouquet.

Explanation:

Let's assume that Maria bought x daisies and y tulips. Since the total number of flowers in the bouquet is 12, we can write the equation: x + y = 12.

Also, the total cost of the bouquet is $12.52. Using the cost per flower, we can write another equation: 0.99x + 1.15y = 12.52.

Now we have a system of equations that we can solve. Multiplying the first equation by 0.99, we get 0.99x + 0.99y = 11.88. Subtracting this equation from the second equation eliminates the x term, giving us 0.16y = 0.64. Dividing both sides by 0.16, we find that y = 4.

Substituting this value back into the first equation, we can solve for x: x + 4 = 12, x = 8.

Therefore, Maria bought 8 daisies and 4 tulips in the bouquet.
