Se distribuyen 400 bolsas en tres urnas sabiendo que la primera tiene 80 menos que la segunda y esta tiene 60 menos que la tercera, averigua cuántas bolsas tiene cada una.

Answers

Answer 1

Answer:

Primeras urnas = 60 bolsas

Segundas urnas = 140 bolsas

Terceras urnas = 200 bolsas

Step-by-step explanation:

Deje que las urnas se representen de la siguiente manera

Primeras urnas = a

Segundas urnas = b

Terceras urnas = c

Se nos dice en la pregunta

400 bolsas se distribuyen en tres urnas

Por lo tanto,

a + b + c = 400 bolsas ......... Ecuación 1

Por la pregunta sabemos que

1) El primero tiene 80 menos que el segundo

a = b - 80

2) Y este segundo tiene 60 menos que el tercero

b = c - 60

Por tanto, c = b + 60

Por lo tanto, sustituimos b - 80 por ayb + 60 por c en la Ecuación 1

a + b + c = 400 bolsas ......... Ecuación 1

b - 80 + b + b + 60 = 400 bolsas

Recopilar términos similares

b + b + b - 80 + 60 = 400 bolsas

3b = 400 + 80 - 60

3b = 420

b = 420/3

b = 140 bolsas

Por lo tanto, el número de bolsas en la segunda urna = 140 bolsas

Dado que a = b - 80

a = 140 bolsas - 80

a = 60 bolsas

Por lo tanto, el número de bolsas en la primera urna = 60 bolsas

Dado que c = b + 60

b = 140 bolsas

c = 140 + 60

c = 200 bolsas.

El número de bolsas en las terceras urnas = 200 bolsas.

- 0.75p - 2 =0.25p​

Answers

Answer: p = -2

Step-by-step explanation:

- 0.75p - 2 =0.25p​                           add .75p on both sides

-2 = p                                                  That's the same thing at p = -2

Answer:

p = -2

Step-by-step explanation:

-0.75p - 2 = 0.25p Subtract 0.25p from both sides

-1p - 2 = 0 Add 2 to both sides

-1p = 2 Divide by -1 on both sides

p = -2

OD. 25°, 50°
O E
E. 35º, 70°

Answers

Answer:

E. 35°, 70°

Step-by-step explanation:

Sum of angles add up to 180° in every triangle.

Step 1: Set up equation

a + 2a + 75 = 180

Step 2: Combine like terms

3a + 75 = 180

Step 3: Subtract 75 on both sides

3a = 105

Step 4: Divide both sides by 3

a = 35

So 1 angle is 35°

Step 5: Plug in a to find last angle

2(35) = 70°

On a vertical line segment, point A is located at 50. Point B is located at 104. Point P is a point that divides segment AB in a ratio of 1:5 from A to B. Where is point P located?

Answers

Answer:

Step-by-step explanation:

Let the initial point on the line segment be O. If point A is located at 50 and point B is located at 104, then OA = 50 and OB = 104. Using the vector notation;

AO+OB = AB

(-OA)+OB = AB

-50+104 = AB

AB = 54

If point P divides the segment AB in a ratio 1:5, them AP:PB = 1:5

AP = 54/6

AP = 9

PB = 54-9

PB = 45

Hence the point P is located at 9 units from A and 45 units from B

Step-by-step explanation:

x * x - x + 4x - 4

x^2 - x + 4x - 4

x^2 + 3x - 4

Answer: x^2+3x-4

=============================================

Explanation:

You can use the FOIL rule to expand out (x+4)(x-1), but here's another way you could do it.

Let y = x+4

This means we replace (x+4) with y to get y(x-1)

Distribute the y term through to get yx-y which can be written as x(y) - 1(y)

After this, replace y with x+4 getting x(x+4)-1(x+4)

Distribute a second time and simplify like so

x(x+4)-1(x+4)

x^2+4x-1x-4

x^2+3x-4

100 trout are seeded into a lake. Absent constraint, their population will grow by 70% a year. The lake can sustain a maximum of 2000 trout. How many trout will be in the lake after 2 years.

Answers

After 2 years, the population of trout in the lake will be 2000 trout.

Given:

Initial population = 100

Growth rate = 70%

Time= 2 years

After the first year:

Population after 1 year = Initial population + (70% of the initial population)

                                      = 100 + (0.7 * 100)

                                      = 100 + 70

                                      = 170 trout

After the second year:

Population after 2 years = Population after 1 year + (70% of the population after 1 year)

                                       = 170 + (0.7 * 170)

                                       = 170 + 119

                                       = 289 trout

Since the calculated population exceeds this limit, the population will be limited to the maximum capacity of 2000 trout.

Therefore, the population of trout in the lake will be 2000 trout.

if the width is 8 less than the length of a rectangle and the perimeter is 48 find the width

Answers

Answer:

Widyh = 8 units

Step-by-step explanation:

Perimeter = 2/width+length)

then:

48 = 2(W+L)

W = L-8

W = Width

L = Length

then:

48 = 2((L-8)+L)

48 = 2(2L88)

48 = 2*2L - 2*8

48 = 4L - 16

48 + 16 = 4L

64 = 4L

L = 64/4

L = 16

W = L-8

W = 16-8

W = 8

Check:

48 = 2(16+8)

48 = 2*24

Nora took 10 bottles of water to a picnic. Of these bottles of water, she and her friends opened a certain number of bottles, b. What expression can be used to determine the number of unopened bottles at the end of the picnic?

Answers

Answer:

10 - B = U

Step-by-step explanation:

U stands for the unopened bottles

for example if they opened 3 bottles it would be 10 - 3 = U (unopened bottles)

The value of U is 7 because the 10 bottles of water minus the 3 bottles they opened it would equal 7.

therefore the equation 10 - B = U shows the amount of unopened bottles

Answers

Answer:

24x-15

Step-by-step explanation:

Let's do this together with a step-by-step explanation!

First we need to make sure we remember that there are appropriate ways on how to solve these. LIKE PEMDAS.

6x + 3 (2x) - 7 - 2³

Let's multiply the 3 and 2x together.

6x + 6x - 7 - 2³

Now let's do the exponent

6x + 6x - 7 - 8

Now let's add everything together! But remember only common variables can be added together.

24x - 15 is the answer.

You can no longer break anything down.

I really hope this helped you!

Answer:

12x - 15

Step-by-step explanation:

so you would have to do the order of operations. so your exponent would be first. so 2×2×2=8.

6x + 3 (2x) -7 + 8

Now you can look at your parentacese which is (2x) so you need to do 3(2x) which gets you 6x.

6x + 6x -7 + 8

So you need to combine like terms.

so starting with the x

6x + 6x = 12x

Now your equation looks like this

12x + -7 +8

now you need to add like terms. (numbers)

-7 -8

so your answer is

12x -15

The parameter given are;

To 12 × 15 by changing the numbers into friendlier numbers

The product in 12 × 15 written with friendlier numbers (or in a simplified format can be given as follows;

12 × 15 = (10 + 2) × (10 + 5)

Which gives;

(10 + 2) × (10 + 5) = 10² + 10 × 5 + 2 × 10 + 2 × 5

From which we have;

10² + 10 × 5 + 2 × 10 + 2 × 5 = 100 + 50 + 20 + 10 = 180

Therefore;

12 × 15 = 180.
