-4x - 12 = 8

     + 12  +12

<u>-4x </u>=<u> 20</u>

-4     -4

<em>x = -5</em>

To ensure that x equals -5, let's substitute the negative integer with x.

-4 x -5 - 12 = 8

-20 - 12 = 8

8 = 8

Therefore, the answer is x = -5 because we confirmed our answer by substituting x with -5 and solving the equation and got the both sides of the equation equal.

-4x-12=8
Add12 to both sides
-4x= 20
Divide both sides by -4
X= -5

Sloan [31]

The number of bats that there would be in 2021 would be 768,000.

<h3>What would be the number of bats in 2021?</h3>

The formula that can be used to determine the future value of bats in 2021 is:

FV = P (1 + r)^n

Where:

  • FV = Future value
  • P = Present value = 3000
  • R = interest rate = 300%
  • N = number of years = 4

3000(1 + 3)^4

3000 x 4^4 = 768,000

A frog has fallen into a pit that is 30m deep. Each day the frog climbs 3m but falls 2m at night. How many days those it takes t
lions [1.4K]

Answer:

28 days

Step-by-step explanation:

because the frog climbs 3m in the day, but falls 2m at night, it technically climbs 1m every 24 hours. this means after the 1st day, it will have climbed a total of 1m, on the second, it will have climbed a total of 2m, and so on. however, when it gets nearer to the top, that's when things start to change. after the 26th day, it will have climbed 26m. on the 27th day, it will be 27m, but then when it jumps 3m the next day, it will reach 30m total before it falls during the night and it will be able to get out of the hole.

i hope this helps! :)

So,

1. Tawni swam a 50-m Freestyle in 40.8 secs.
2. Pepita swam a 100-m Butterfly in 60.2 secs.
3. Susana swam a 200-m Medley in 112.4 secs.

Manipulate the distances so that they are the same.

Tawni would swim a 200-m in 163.2 secs.
Pepita would swim a 200-m in 120.4 secs.
Susana woulld swim a 200-m in 112.4 secs.

Susana swam the fastest.

Quadrilateral TRAM is rotated -90 degrees about the origin. Draw the image of this rotation.
SpyIntel [72]

Answer:

Please find attached the image of the quadrilateral TRAM after a rotation of -90 degrees, created with MS Excel

Step-by-step explanation:

The given coordinates of the vertices of the quadrilateral TRAM are;

T(-5, 1), R(-7, 7), A(-1, 7), M(-5, 4)

By a rotation of -90 degrees = Rotation of 90 degrees clockwise, we get;

The coordinates of the preimage before rotation = (x, y)

The coordinates of the image after rotation = (y, -x)

Therefore, we get for the the quadrilateral T'R'A'M', by rotating TRAM -90 degrees as follows;

T(-5, 1) → T'(1, 5)

R(-7, 7) → R'(7, 7)

A(-1, 7) → A'(7, 1)

M(-5, 4) → M'(4, 5)

The image of TRAM after -90 degrees rotation is created by plotting the derived points of the quadrilateral T'R'A'M' on MS Excel and joining the corresponding points as presented in the attached diagram.

Jean bought a bag of candy that contained red candies, green candies, and brown candies. Some candies are marked with a smile an
lana66690 [7]
                   | Red    |Green  | Brown   Total
<span>Smile         |0.100  | .300    | .10           0.50</span>
<span>No smile   |0.200  | .150    | .15            0.50
Total           0.30       0.45      0.25         1.00

The probability of choosing red candy is 0.10
The probability of choosing no smile candy is 0.50

The probability of choosing red or no smile = 0.10 + 0.50 = 0.60

I did not use 0.30 as the probability of red because it included the no smile candy. It should only be red candy that has a smile.</span>
