Question in the picture

The correct solution are:  ( − 6 ) ( − 2 ) = 12 and  ( − 6 ) ( − 6 ) = 36 .

Here it is important to remember the rules for the  addition of integers numbers:

+  +   Add  Final result (+) - Final result (+)  

-   -   Add  Final result (-) - Final result (-)  

+  -   Subtract - Final result (the sign of the integer having a greater value)

-   +  Subtract - Final result (the sign of the integer having a greater value)

The rules for multiplication of numbers are:

The result presents a positive sign (+) because the signs are the same.

  +  - or   -   +

The result presents a negative sign (-) because the signs are different.

For solving this question, you should apply the rules presented previously. And after that check, if your result is the same that the question gives.

        ( − 6 ) 2 − ( 6 ) ( 6 ) = 36

        -12 -(36) = -12 -36 = -48 -> It is not the solution given in the exercise because  -48 ≠ 36.

        ( − 6 ) ( − 2 ) =12

                12=12 -> It is the solution given in the exercise because  12=12.

      ( − 6 ) ( − 6 ) = 36

               36=36-> It is the solution given in the exercise because  36=36.

       ( − 6 ) ( − 6 ) = − 36

            36≠ -36 -> It is not the solution given in the exercise because  36 ≠ -36.

Answer:

x = 92/11

Step-by-step explanation:

10x + 1 + 12x - 5 = 180

*group the like terms*

(10x + 12x) + (1-5) = 180

*simplify*

22x - 4 = 180

*add four on both sides to cancel out -4*

+4. +4

*simplify*

22x = 184

*divide both sides by 22 to cancel out the quantity and solve for x*

÷22 ÷22

*simplify*

x = 92/11

Answer:

x = 92/11, x = 8.36 repeating the .36, or x = 8 4/11

Answer:

After 5 hours.

35 bacteria cells.

Step-by-step explanation:

Andy’s population is represented by [tex]B=6x+5.[/tex]

Samantha’s population is represented by [tex]B=2^x+3[/tex]

Where B represents the total population given the number of hours x.

We want to find at what hour will their population be the same. We are told to use graphing technology.

Graphing them, we will get the graphs below.

Graphically, their population will be the same where the two graphs intersect.

So, we can see that they intersect at (5, 35).

Therefore, after 5 hours, the total number of bacteria cells for both experiments will be the same.

And the total number of bacteria at that time will be 35 bacteria cell.

1/8k + 80 = 1/2k + 120

Step 1: Subtract 1/2k from both sides.

1/8k + 80 - 1/2k = 1/2k + 120 - 1/2k

-3/8k + 80 = 120

Step 2: Subtract 80 from both sides.

-3/8k + 80 - 80 = 120 - 80

-3/8k = 40

Step 3: Multiply both sides by 8/(-3).

(8/-3) x (-3/8k) = (8/-3) x (40)

Answer: k = -320/3 or −106.667

If the number is the same for the numerator and denominator it adds up to 1.

More examples:

6/10 + 4/10 = 10/10 = 1

9/15 + 6/15 = 15/15 = 1

Answer:

Step-by-step explanation:

in this problem we are looking at an alternative expression to the given expression for the total earning which is

Given data

T=11.50x + 125 + 11.50y + 153

let us collect like terms we have

T=11.50x + 11.50y + 153+ 125

T=11.50x + 11.50y +278

we can factor out 11.5 since it is common

T=11.50(x +y) + 278

The alternative expression the girls could use is

T=11.50(x +y) + 278

Answer:

[tex]a_{n}[/tex] = 4n - 2

Step-by-step explanation:

There is a common difference d between consecutive terms in the sequence, that is

6 - 2 = 10 - 6 = 14 - 10 = 18 - 14 = 4

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 2 and d = 4 , thus

[tex]a_{n}[/tex] = 2 + 4(n - 1) = 2 + 4n - 4 = 4n - 2

Answer:

t = 17

Step-by-step explanation:

Plug in 46 for H(t) into the above equation and solve for t.

46 = 3t - 5 (add 5 to both sides)

51 = 3t (divide both sides by 3 to isolate t)

17 = t or t = 17

Answer:

108.9

Step-by-step explanation:

30.3 + 40.8= 71.1

180 - 71.1= 108.9

The measure of unknown ∠m is equal to 108.9°.

According to the triangle inequality theorem the sum of the length of any two sides will always be greater than the third side. Mathematically -

(a + b) > c

Given is a triangle with its angle measurements.

We know that the sum of the angles of a triangle is equal to 180 degrees.

Therefore, we can write -

∠m + 30.3° + 40.8° = 180°

∠m = 180° - 71.1°

∠m = 108.9°

Therefore, the measure of unknown ∠m is equal to 108.9°.

Answer:

Answer is -24/25.

Step-by-step explanation:

Got it right on egde2020

The value of cos (t) is - (24/25), as per  the relation between the sine and cosine of an angle.

For any angle 'Ф',  the relation between the sine and cosine of an angle is:

sin² (Ф) + cos² (Ф) = 1, when 0 < Ф < (π/2)

Given equation,

sin (t) = (7/25), for (π/2) < t < π

Here, 't' is in the second quadrant.

Therefore, sine is positive here.

However, cosine is negative there.

Therefore, the value of cos (t) is

= - √[1 - sin² (t)]

= - √[1 - (7/25)²]

= - √[1 - (49/625)]

= - √(576/625)

= - (24/25)
