6=x

Step-by-step explanation:

Step-by-step explanation:

-3/8 × 1 × -9/10 × -8/3

we know

- × - = +

+ × - = -

therefore, since we have 3 negative factors we get a negative result.

we can ignore the completely neutral multiplication by 1.

-3/8 × -9/10 × -8/3 = -(3×9×8)/(8×10×3) = -9/10

Rewriting the whole as an Equivalent Fraction

4.1   Adding a whole to a fraction

Rewrite the whole as a fraction using  (x-8)  as the denominator :

         -2     -2 • (x - 8)

   -2 =  ——  =  ————————————

         1        (x - 8)  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

4.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

3x2 + -2 • (x-8)     3x2 - 2x + 16

————————————————  =  —————————————

   1 • (x-8)          1 • (x - 8)

Trying to factor by splitting the middle term

4.3     Factoring  3x2 - 2x + 16

The first term is,  3x2  its coefficient is  3 .

The middle term is,  -2x  its coefficient is  -2 .

The last term, "the constant", is  +16

Step-1 : Multiply the coefficient of the first term by the constant   3 • 16 = 48

Step-2 : Find two factors of  48  whose sum equals the coefficient of the middle term, which is   -2 .

     -48    +    -1    =    -49

     -24    +    -2    =    -26

     -16    +    -3    =    -19

     -12    +    -4    =    -16

     -8    +    -6    =    -14

     -6    +    -8    =    -14

Step-by-step explanation:

I might be wrong but i rlly hope this helps u in some way :)

Answer:

[tex]3c > -26[/tex]

Step-by-step explanation:

"The product of c and 3" means to multiply c with 3: [tex]c * 3[/tex] or [tex]3c[/tex]

"is greater than": [tex]>[/tex]

"-26": -26

Put the terms together:

Step-by-step explanation:

Answer:

B) 0.42

Step-by-step explanation:

population density=number of people/square units

we plug in 2,100 for the first one but we don't know the second one for that we need the area which is A=π[tex]r^{2}[/tex] so the radius is 40 millimeters so [tex]40^{2}[/tex] =1600 1600*π=5024

2,100/5024=0.417 round it up and it is 0.42

so B) 0.42 is the answer

Step-by-step explanation:

By using the quadratic formula, we can conclude that the golf ball will hit the ground at x = 0.5 seconds.

What is the quadratic formula?

The quadratic formula is a formula that gives the solutions of a quadratic equation in the form [tex]ax^2 + bx + c = 0[/tex], where a, b, and c are constants and x is the variable. The formula is:

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

This formula can be used to find the values of x that satisfy the quadratic equation.

To find when the golf ball will hit the ground, we need to find the value of x when the height of the golf ball is equal to zero. We can do this by solving the quadratic equation [tex]-16x^2 + 11x + 6 = 0[/tex] using the quadratic formula:

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

where a = -16, b = 11, and c = 6. Substituting these values, we get:

x = (-11 ± [tex]\sqrt{11^2 - 4(-16)(6)}[/tex] ) / 2(-16)

x = (-11 ±  [tex]\sqrt{361}[/tex])/ (-32)

Simplifying this expression, we get:

x = (-11 ± 19) / (-32)

So the two possible values of x are:

x = 8/16 = 0.5 and x = 30/16 = 1.88

Since the height of the golf ball is equal to zero when it hits the ground, we can conclude that the golf ball will hit the ground at x = 0.5 seconds (rounded to the nearest hundredth).

Answer: x=3

Step-by-step explanation:

Explicación paso a paso:

Dado

an = n + 3

bn = 5n-1

a) an-bn = n + 3- (5n-1)

= n + 3-5n + 1

= n-5n + 3 + 1

= -4n + 4

an-bn = 4-4n

b) an + 3bn = (n + 3) +3 (5n-1)

= n + 3 + 3 (5n) +3 (-1)

= n + 3 + 15n-3

= n + 15n + 3-3

= 16n + 0

= 16n

an + 3bn = 16n

3) Dado a1 = 1, a2 = 1

an = an-1 + an-2

Debemos escribir los primeros ocho términos de la secuencia.

a3 = a3-1 + a3-2

a3 = a2 + a1

a3 = 1 + 1

a3 = 2

a4 = a3 + a2

a4 = 2 + 1

a4 = 3

a5 = a4 + a3

a5 = 3 + 2

a5 = 5

a6 = a5 + a4

a6 = 5 + 3

a6 = 8

a7 = a6-a5

a7 = 8 + 5

a7 = 13

a8 = a7 + a6

a8 = 13 + 8

a8 = 21

Por tanto, los primeros ocho términos de la secuencia son 1, 1, 2, 3, 5, 8, 13 y 21

Part B: (3,4)

Explain: (3,4) is the place where the lines intersect.

Answer:

C

Step-by-step explanation:

supplementary angles sum to 180° , then

3x + 15 + 60 = 180 , that is

3x + 75 = 180 ( subtract 75 from both sides )

3x = 105 ( divide both sides by 3 )

x = 35

Answer: 160 miles

Step-by-step explanation: From 10:20 to 12:20 is 2 hours which is 120 minutes and it is 60mph so it is 1 mile per minute. 12:20 to 1:00 is 40 minutes so you add 40 to 120 which makes it 160. So the answer is 160 miles

Answer:

  5x + 12 = 5x - 7

Step-by-step explanation:

There will be no solution when the coefficients of x are the same on both sides of the equal sign and the constants are different. That is the case for ...

  5x + 12 = 5x - 7

This reduces to ...

  19 = 0 . . . . . no value of x will make this be true: NO SOLUTION

Answer:

The blue and yellow macaw is 33 inches long.

Step-by-step explanation:

If the toucan is 22 inches long and it's two thirds the length of the macaw you can divide by two to find what one third is.

22 ÷ 2 = 11

So then you have to multiply by 3 to find what the full length is.

3 x 11 = 33 inches

Hope that helps and have a great day!

Answer:
