Answer:

1/6+−2/9=−1/18

Step-by-step explanation:

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(16×33)+(−29×22)=?

Complete the multiplication and the equation becomes

318+−418=?

The two fractions now have like denominators so you can add the numerators.

Then:

3+−418=−118

This fraction cannot be reduced.

Therefore:

16+−29=−118

LCM is 3 (x + 1)(x - 5)(x + 2)

Step-by-step explanation:

Given polynomials are:

x2 - 4x – 5 and x2 – 3x – 10.

Factorizing x^2-4x-5

[tex]x^2-4x-5\\= x^2-5x+x-5\\=x(x-5)+1(x-5)\\=(x+1)(x-5)[/tex]

Factorizing  x^2 – 3x – 10

[tex]x^2 -3x -10\\=x^2-5x+2x-10\\=x(x-5)+2(x-5)\\=(x+2)(x-5)[/tex]

Looking at the fators of both polynomials we can see:

The LCM will be the combination of all factors of polynomials. The factor that occurs in both factorization will be written only once

Hence,

LCM is 3 (x + 1)(x - 5)(x + 2)

Answer:

E

Step-by-step explanation:

You just multiply 16 by 4.

There are 16 ounces in one pound.

So, 64 ounces in 4 pounds.

The correct option is E.

Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

Given:

There are 16 ounces in one pound.

In 4 pounds,

= 16 x 4 ounces.

= 64 ounces.

Step-by-step explanation:

2/3 se converte en 10/15

y 1/5 se converte en 3/15

Entonces le va a quedar 10/15-3/15 = 7/15 de la tablilla de chocolate.

Answer:

2/3 - 1/5 = 7/15

Step-by-step explanation:

tienes que obtener denominadores iguales para restar las fracciones para obtener una respuesta. El denominador que tiene 3 y 5 igual es 15. así que tienes que multiplicar 3 por 5 y 5 por 3 y todo lo que hagas abajo deberías hacerlo al number de arriba.

Answer:

Part 1)  [tex]x^{2} -2x-2=(x-1-\sqrt{3})(x-1+\sqrt{3})[/tex]

Part 2)  [tex]x^{2} -6x+4=(x-3-\sqrt{5})(x-3+\sqrt{5})[/tex]

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form

[tex]ax^{2} +bx+c=0[/tex]

is equal to

[tex]x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}[/tex]

Part 1)

in this problem we have

[tex]x^{2} -2x-2=0[/tex]

so

[tex]a=1\\b=-2\\c=-2[/tex]

substitute in the formula

[tex]x=\frac{-(-2)(+/-)\sqrt{-2^{2}-4(1)(-2)}} {2(1)}\\\\x=\frac{2(+/-)\sqrt{12}} {2}\\\\x=\frac{2(+/-)2\sqrt{3}} {2}\\\\x_1=\frac{2(+)2\sqrt{3}} {2}=1+\sqrt{3}\\\\x_2=\frac{2(-)2\sqrt{3}} {2}=1-\sqrt{3}[/tex]

therefore

[tex]x^{2} -2x-2=(x-(1+\sqrt{3}))(x-(1-\sqrt{3}))[/tex]

[tex]x^{2} -2x-2=(x-1-\sqrt{3})(x-1+\sqrt{3})[/tex]

Part 2)

in this problem we have

[tex]x^{2} -6x+4=0[/tex]

so

[tex]a=1\\b=-6\\c=4[/tex]

substitute in the formula

[tex]x=\frac{-(-6)(+/-)\sqrt{-6^{2}-4(1)(4)}} {2(1)}[/tex]

[tex]x=\frac{6(+/-)\sqrt{20}} {2}[/tex]

[tex]x=\frac{6(+/-)2\sqrt{5}} {2}[/tex]

[tex]x_1=\frac{6(+)2\sqrt{5}}{2}=3+\sqrt{5}[/tex]

[tex]x_2=\frac{6(-)2\sqrt{5}}{2}=3-\sqrt{5}[/tex]

therefore

[tex]x^{2} -6x+4=(x-(3+\sqrt{5}))(x-(3-\sqrt{5}))[/tex]

[tex]x^{2} -6x+4=(x-3-\sqrt{5})(x-3+\sqrt{5})[/tex]

Answer:

the number of candy bars they have is not affected by the other factors like the budget or the student council

Final answer:

The number of candy bars is the independent variable because it can be manipulated or changed by the student council to affect the amount of money they earn.

Explanation:

The number of candy bars is considered the independent variable in this scenario. The independent variable is the one that is manipulated or changed in an experiment, and its value does not depend on any other variable.

In this case, the student council is selling candy bars to earn money for their budget, and the number of candy bars they sell is the variable that they have control over.

By increasing or decreasing the number of candy bars sold, they can affect the amount of money they earn for their budget.

Answer:

Rob is 76 cm tall.

Step-by-step explanation:

Let b = height of bill.

Let m = height of Mary.

Let r = height of Rob.

"the total heigh of bill mary and rob is 180 cm"

b + m + r = 180         Equation 1

"bob* is twice as tall as bill"

*I think you meant Rob is twice as tall as Bill.

r = 2b

"mary is 28 cm taller than bill"

m = b + 28

Substitue r = 2b and m = b + 28 into Equation 1.

b + b + 28 + 2b = 180

4b + 28 = 180

4b = 152

b = 38

r = 2b

r = 2(38) = 76

Rob is 76 cm tall.

Rob height is 76cm.

Given that,

According to the given data, computation of the data are as follows,

Let Bill height be X, then Rob height is 2X and Mary height is X + 28.

So, X + 2X + X + 28 = 180cm

4X = 180 - 28

X = 152 [tex]\div[/tex] 4

X = 38

Hence, Bill height = X = 38cm

Rob height = 2X = 76cm

Mary height = X + 28 = 66cm

Answer:

95 nickels 19 dimes

Step-by-step explanation:

d=dimes

5d=nickels

0.05(5d) + 0.10(d) = 6.65

0.25d + 0.10d = 6.65

0.35d=6.65

Divide by 0.35

d= 19 (19 coins)

19 dimes =$1.9

6.65-1.9= $4.75

Nickels=$4.75

4.75/0.05 = 95 coins

19*5=95

  114 coins in total

19*0.10 = 1.9

95*0.05=4.74

4.75+1.9= 6.65

Answer:

There are 19 dimes and 95 nickels

Step-by-step explanation:

Represent the numbers of nickels and dimes by n and d.  Then n = 5d.

The value of the nickels is $0.05n and that of the dimes is $0.10d.  Together these two amounts come to $6.65:

$0.05n + $0.10d = $6.65.

But n = 5d.

Substituting 5d for n, we get:

$0.05(5d) + $0.10d = $6.65

Combining the two terms on the left, we get:

0.25d + 0.10d = 6.65, or

0.35d = 6.65.

Solving for d, we get d = 6.65/0.35, or d = 19.  Since n = 5d, n = 5(19) = 95.

There are 19 dimes and 95 nickels.

Answer:

Spending will be more than $59 billion more than 4 years after 2000.

Step-by-step explanation:

Given:

[tex]y=11.3x + 13.8[/tex]

x is the number of years.

Business spending is $59 billion.

Hence we can say that y = $59.

Now Substituting the value of y in above equation we will find the value of x in number of years.

[tex]11.3x+13.8=59\\11.3x=59-13.8\\ 11.3x= 45.2\\\\x=\frac{45.2}{11.3} = 4 years.[/tex]

Hence we can say that,

After 4 years after 2000 the spending will be more than $59 billion.

or

Spending will be more than $59 billion more than 4 years after 2000.

The equation demonstrates that the spending will exceed $59 billion more than 4 years after 2000.

To solve the problem, we first need to set the equation y = 11.3x + 13.8 to greater than 59, as we are trying to find out when the spending will be more than $59 billion. The equation will therefore be, 11.3x + 13.8 > 59.

Then, we subtract 13.8 from both sides of the equation to isolate the term with x, resulting in 11.3x > 45.2.

Finally, we divide each side by 11.3 to solve for x, which will give us x > 4. Consequently, the spending will be more than $59 billion more than 4 years after 2000.
